The gas sensing layer is sandwiched between a stainless steel washer (counter electrode) and a stainless steel cap (working electrode), together with gas diffusion control stainless film and backing layers. This assembly is placed in the compartment of the stainless steel can. Water is stored in the bottom compartment and a charcoal filter is installed inside the stainless steel cap.1-4 Basic measuring circuitF igure 2 shows the basic measuring circuit of TGS5042. The sensor generates a minute electric current which is converted into sensor output voltage (Vout) by an op-amp/ resistor (R1) combination.Figaro recommends the following electrical parts:R1 : 1MΩC1 : 1µFIC : AD708An additional resistor or F ET is required to prevent polarization of the sensor when circuit voltage is off. NOTE: When voltage is applied to the sensor output terminal, the sensor may be damaged. Voltage applied to the sensor should be strictly limited to less than ±10mV.1-5 Operating conditions & specifications (Table 1)Figure 1 - Sensor structureFigure 2 - Basic measuring circuit(Including equivalent circuit)Cap /Working electrodeVoutNOTE 1: Sensor output in air under operating conditionsNOTE 2:If the water in the reservoir should freeze very rapidly (typically occurs only under artifically created conditions), irreversible change to sensor characteristics would occur. To avoid this risk, the sensor is recommended to be positioned with its cap (working electrode) facing up. NOTE 3: Please contact Figaro for more information if the required temperature range would exceed the specified limits.Table 1 - Operating conditions and specifications1-6 Mechanical strengthThe sensor shall have no abnormal findings in its structure and shall satisfy the above electrical specifications after the following performance tests: Withstand force -withstand force of 10kg (cap from metal can) along a vertical axisVibration - frequency--10~500Hz (equiv. to 10G), duration - 6 hours, x-y-z directionShock - acceleration-100G, repeat 5 times 1-7 Dimensions (see Fig. 3)Figure 3 - DimensionsAll sensor characteristics shown in this brochu re represent typical characteristics. Actu al characteristics vary from sensor to sensor and from production lot to production lot. The only characteristics warranted are those shown in the Specification.NOTE: The sensor can be supplied with lead pins. Please refer to the Appendix for detailsTop viewBottom viewSide view2. Operation PrincipleThe electrolyte of TGS5042 is a very low concentra-tion of mixed/prepared alkaline electrolyteconsisting of KOH, KHCO 3, and K 2CO 3. Themixed alkaline electrolyte acts as a buffer solution with a pH value maintained between 7~10. When CO passes through the backing layer and reaches to the working electrode, electrons are generated resulting from the reaction between CO and anionsin the electrolyte such as OH -, HCO 3-, and CO 32-(see equations 1a~1c ). By creating a short circuitbetween the working and counter electrodes with external wiring, electrons move to the counter electrode through the external wiring. At that point, the consumed anions in the electrolyte at the working electrode are replenished and move to the electrolyte by the reaction of CO 2, water, and electrons as shown in equations 2a~2c. The total reaction is expressed as shown in equation 3.A linear relationship exists between the sensor'selectric current and CO concentration (see equation 4). By calibrating the sensor with a known concentration of CO gas, the output current of the sensor can then be used to quantitatively determine CO concentration.Since, unlike conventional dry batteries, there is no consumption of active materials or of the electrodes, TGS5042 possesses excellent long-term stability for its output signal and enables maintenance-free operation. Furthermore, the sensor's self-generating output current makes it ideal for usage in battery-operated CO detectors.Figure 4 - Operation principleFigure 5 - Schematic diagram of TGS5042operating principleSeparator immersed in liquid alkaline electrolyteWorking electrode (Anodic reaction)CO + 2OH - → CO 2 + H 2O + 2e - (equation 1a )CO + 2HCO 3- → 3CO 2 + H 2O + 2e - (equation 1b )CO + CO 32- → 2CO 2 + 2e - (equation 1c )Counter electrode (Cathodic reaction)1/2O 2 + H 2O + 2e - → 2OH - (equation 2a ) 1/2O 2 + 2CO 2 + H 2O + 2e - → 2HCO 3- (equation 2b ) 1/2O 2 + CO 2 + 2e - → CO 32- (equation 2c )Total reactionCO + 1/2 O 2 → CO 2 (equation 3)Theoretical output current valueI = F x (A/σ) x D x C x n (equation 4) where :F : Faraday constant A: Surface area of diffusion filmD: Gas diffusion co-efficient C: Gas concentration σ: Thickness of diffusion filmn: Number of reaction electrons深圳市深国安电子科技有限公司3. Basic Sensitivity Characteristics 3-1 Sensitivity to various gasesF igure 6 shows the sensor’s sensitivity to various gases. The Y-axis shows output current (Iout/µA) in each gas. The output current is linear to CO concen-tration, with a deviation of less than ±5% in the range of 0~500ppm. Cross sensitivity data for other gases than those in Figure 6 are tabulated in Table Y.3-2 Temperature and humidity dependencyF igure 7a shows the temperature dependency of TGS5042 under a constant humidity of 50%RH. The Y-axis shows the ratio of output current in 400ppm of CO at various temperatures (I) to the output current in 400ppm of CO at 20˚C/50%RH (Io). Temperature dependency is based on the difference in the catalytic reaction rate on the electrodes, and it can be simply compensated by utilizing a thermistor. This linear relationship between I/Io and CO concentration is constant regardless of CO concentration range, according to the sensor's operating principle.F igure 7b shows the humidity dependency of TGS5042 under constant temperatures of 20˚C and 50˚C. The Y-axis shows the ratio of output current in 400ppm of CO at various relative humidities (I) to the output current in 400ppm of CO at 20˚C/50%RH (Io). This data demonstrates that humidity dependency is negligible as temperature varies.Figure 6 - Sensitivity to various gasesFigure 7a - Temperature dependency at 400ppm CO/50%RH(Io=sensor output current at 20˚C)Figure 7b - Humidity dependency at 400ppm CO(Io=sensor output current at 50%RH)0.00.51.01.52.020406080100Relative Humidity (%)Note : The figures in this table are typical values and should not be used as a basis for cross calibration. Cross sensitivity for various gases may not be linear and should not be scaled. All data based on a 4 minute exposure. For some gases, filter saturation and gas breakthrough mayoccur if gas is applied for a longer time period.0.00.51.01.52.0-10102030405060Temperature (˚C)3-3 Gas response patternF igure 8 shows the gas response pattern of the output signal when the sensor is placed into 30, 70, 150 and 400ppm of CO and then returned to normal air. The response time to 90% of the saturated signal level is within 60 seconds, and the recovery of the signal back to 90% of the base level is within 120 seconds. This data demonstrates that TGS5042 possesses sufficient response speed for meeting UL requirements for CO detectors.3-4 RepeatabilityF igure 9 shows the pattern of the output signal when the sensor is repeatedly exposed to 400ppm of CO at a constant interval of 240 seconds. The data demonstrates extremely high reproducibility of the output signal, the deviation being less than ±5%.3-5 Influence of storageF igure 10 shows the initial action of the sensor's output current signal in fresh air. F or the purpose of this test, sensors were stored for more than six months under two separate conditions between the working and counter electrodes: in short-circuited condition, and in open-circuited condition. The chart illustrates the behavior of sensor output current for each group just after installation into the operating circuit. The output current signal of sensors stored in a short-circuited condition reaches its saturated level quickly, while those stored with an open-circuit exhibit much slower behavior. Since sensors are shipped in an open-circuit condition, stabilization time of one hour (typical) is recommended. If an anti-polarization circuit is used (see Item 2-5 in Application Notes for TGS5042), placing the sensor onto the pcb for one hour should be sufficient to stabilize the output. If no anti-polarization circuit is used, placing the sensor into the detector circuit and powering the circuit for about one hour should be sufficient to stabilize sensor output.Figure 8 - Response patternFigure 9 - Repeatability (in 400ppm of CO)0.00.20.40.60.81.00500100015002000Time (sec.)-0.20.00.20.40.60.81.00500100015002000Time (sec.)Figure 10 - Influence of storage(in fresh air)Figure 11a shows the result of the “Normal Operation Test” required by UL2034, Sec. 35.3 where the sensor is exposed to 600ppm of CO for 12 hours at 20˚C/40%RH. Stable output current signal can be seen throughout the exposure.In addition, F igure 11b shows the CO sensitivity characteristics of the sensor before, during, and after the Normal Operation Test, demonstrating that TGS5042 is hardly influenced by exposure to high concentrations of CO.3-7 Sensitivity testFigure 12a shows the results of the “Sensitivity Test” as required by UL2034, Sec. 38. Under this test, the sensor was exposed to 30, 70, 150 and 400ppm of CO at 20˚C/40%RH. The period of exposure was varied by concentration, corresponding with the maximum time in which a CO detector should generate an alarm for the subject concentration. Throughout the test exposures, TGS5042 displayed a reasonable and stable output current signal.Figure 11a - Normal operation test (CO 600±30ppm for 12 hours at 20˚C/40%RH) 0.00.51.01.5Figure 11b - Normal operation test(20˚C/40%RH)0.20.40.60.81Figure 12a - Sensitivity test(20˚C/40%RH)In addition, Figure 12b indicates the CO sensitivity characteristics of the sensor before, during, and after the Sensitivity Test, demonstrating the excellent reproducibility of TGS5042's CO sensitiv-ity characteristics.4. ReliabilityT ests conducted in this section demonstrate that TGS5042 can meet the requirements of various testing standards without incurring adverse long term effects from such tests.4-1 Interference gas testFigure 13a shows the results of testing the TGS5042 sensor for durability against various interference gases as specified by UL2034, Sec. 39. The test was conducted by exposing the sensor to each gas shown in Figure 13a (starting with CO 30ppm) for two hours, then removing the sensor to fresh air for just one hour, and followed by inserting the sensor into the next gas. This procedure was repeated for the full range of gases shown in Figure 13a. Because the sensor is exposed to each of the test gases consecutively, to some small extent the effect of the previous test gas may affect subsequent tests for a short period. However, despite the short-term effects of such gases remaining after exposure, the sensor still shows significantly less sensitivity to each test gas when compared to 30ppm of CO, and CO sensitivity remains unaffected.In addition, F igure 13b shows the CO sensitivity characteristics of the sensor before and after this test, further demonstrating the excellent reproducibility of the CO sensitivity characteristics of TGS5042, demonstrating its durability against the interference gases listed in the requirements of UL2034, Sec. 39.Fig. 12b - Sensitivity test(20˚C/40%RH)Figure 13a - Interference gas test(20˚C/40%RH)-0.020.020.040.060.08AC O30p pM et h an e500ppB ut a ne300p pH ep t an e500ppE th yl ac et a te200p pI P A200ppC O25000ppN H3100p pE th an ol200p pT ol u en e200ppT ri c hl o ro et h an e200ppA ce t on e200ppC O30p p AFigure 13b - Interference gas test(20˚C/40%RH)深圳市深国安电子科技有限公司4-2 Long-term stabilityigure 14 shows long-term stability data for TGS5042. Test samples were stored in natural clean air under a short-circuit condition and measured at various intervals as dictated by the standard test conditions of UL2034, Sec. 38. The Y-axis shows the ratio of output current in 300ppm of CO at any point in time (I) over output current in 300ppm of CO on the first day of the test (Io). This chart demonstrates very stable characteristics with a variation of less than ±15% for more than 7 years.4-3 Corrosion testTo demonstrate the durability of TGS5042 against corrosion, samples were subjected to test conditions called for by UL2034, Sec.58-Corrosion Test. Over a three-week period, a mixture of 100ppb of H2S, 20ppb of Cl2, and 200ppb of NO2 was supplied to the sensors at a rate sufficient to achieve an air exchange rate of five times per hour. Figure 15 shows the CO sensitivity characteristics before and after exposure in the above conditions, demonstrating that TGS5042 is hardly influenced by such corrosive gases. In addition, the sensor's stainless steel housing did not show any sign of corrosion as a result of this test.4-4 Variable ambient temperature testTo demonstrate the ability of TGS5042 to withstand the effects of high and low temperature, the “Variable Ambient Temperature Test” of UL2034, Sec. 45 was conducted.(1) Operation in high and low temperature test Figure 16a shows the results for the “Operation in High and Low Temperature Test” of UL2034, Sec.45.1. The sensor was exposed to environments of 0˚C/15%RH and 49˚C/40%RH for at least three hours each, with measurements taken before and during the exposure in accordance with the test conditions of UL2034, Sec. 38. By plotting the output current values from these test measurements atop the data taken prior to this test at a constant 50%RH (representing standard temperature dependency), it can be seen that the test data are still in line with data taken at a constant RH. The conclusion which can be drawn is that, regardless of exposure to extremes of temperature and humidity, the sensor's output is not affected by humidity. As a result, TGS5042 can meet the requirements of UL2034, Sec. 45.1 by utilizing a simple temperature compensation method.Figure 14 - Long term stabilityFigure 15 - Durability against corrosionFigure 16a - Operation in high and low temperature (all data at 50%RH except Sec. 45.1 test points) 0.00.51.01.52.02.53.0Time (days)(2) Effect of shipping and storageTo verify the effects of shipping and storage, the sensor was tested under the conditions of UL2034, Sec. 45.2. Test samples in a short-circuited condition were subjected to 70˚C for 24 hours, allowed to cool to room temperature for 1 hour, subjected to -40˚C for 3 hours, and then allowed to warm up to room temperature for 3 hours. Figure 16b shows the CO sensitivity characteristics before and after the test, demonstrating that TGS5042 meets the requirement of UL2034, Sec. 45.2.4-5 Humidity testF igure 17a shows the results of testing the sensor under UL2034, Sec. 46A. The sensor was exposed in an atmosphere of 52±3˚C/95±4%RH for a period of 168 hours, returned to normal air for 2 days, then followed by 168 hours exposure at 22±3˚C/10±3%RH. The data demonstrates the stable characteristics in both low and high humidity conditions.Figure 17b shows data taken prior to the above test at a constant relative humidity of 50%. These curves represent the typical temperature dependency of the sensor. When plotting measurements taken at the environmental extremes specified on UL2034, Sec. 46A (52±3˚C/95±4%RH and 22±3˚C/10±3%RH) onto the temperature dependency curves, it can be seen that measurements taken at these extreme conditions still fall in line with the temperature dependency curve derived prior to testing. The conclusion which can be drawn is that, regardless of exposure to extremes of temperature and humidity, the sensor's output is not affected by humidity. As a result, TGS5042 can meet the requirements of UL2034, Sec. 46A by utilizing a simple temperature compensation method.Figure 16b - Effects of shipping and storageFigure 17a - Humidity testFigure 17b - Humidity test(all data at 50%RH except Sec. 46A test points))4-6 Stability test(1) False alarm testTo show the sensor’s behavior under continuous low level exposure to CO, samples were tested against the procedure detailed in UL2034, Sec.41.1(c)-Stability Test. Test samples were exposed to 30ppm of CO continuously for a period of 30 days under standard circuit conditions. Figure 18 shows the CO sensitivity characteristics before and after the exposure test, demonstrating that detectors using TGS5042 will not give a false alarm as a result of continuous low level CO exposure.(2) Temperature cycle testIn accordance with UL2034, Sec. 41.1(e)-Stability Test, test samples were exposed to ten cycles (<1 hour and >15 minutes) of temperature from 0˚C/100%RH to 49˚C/40%RH. F igure 19 shows CO sensitivity characteristics before and after the cycle test, demonstrating that TGS5042 is hardly influenced by the extreme conditions of the temperature cycle test.4-7 Sequential testIn UL2034, Sec. 41.3, a single lot of sample detectors are to be subjected to the following sequence of tests: Section 38, Section 41.1, Section 39, Section 45, and Section 46A. While TGS5042 meets the requirements of each of these test individually (as shown elsewhere in this brochure), this test is designed to demonstrate the sensor's ability to withstand all of these test when conducted in sequence. Figure 20 shows the results of sequentially testing the same lot of sensors. The good stability of the sensor's output signal indicates that TGS5042 can satisfy the requirements of UL2034, Sec. 41.3-Sequential Test.Figure 18 - False alarm testFigure 19 - Temperature cycle testB ef o re te st i ngA ft e rS ec.38t e stA ft e rS ec.41.1t e stA ft e rS ec.39t e stB ef o re Se c.45.1v ar.am bi e nt t em pt e stA ft e rS ec.45.1v ar.am bi e nt t em pt e st(0˚C)A ft e rS ec.45.1v ar.am bi e nt t em pt e st(49˚C)B ef o re Se c.45.2s hi p pi n g/s to r ag et e stA ft e rS ec.45.2s hi p pi n g/s to r ag et e st(-40˚C)A ft e rS ec.45.2s hi p pi n g/s to r ag et e st(70˚C)B ef o re Se c.46Ah i gh hu mi d it yt e st t es tA ft e rS ec.46A hi g hh um id i ty te st t es tA ft e rS ec.46A lo wh um id i ty te st t es tA ft e rs eq ue nt i al t es tA ft e rS ec.35.3t e stFigure 20 - Sequential test4-8 Dust testTo judge the effect of dust contamination on TGS5042, approximately 2 ounces (0.06 kg) of cement dust, capable of passing through a 200 mesh screen, was circulated for 1 hour by means of a blower, enveloping the sensor in the test chamber. Air flow was maintained at an air velocity of approximately 50 fpm (0.25 m/s) at 20˚C/40%RH. Figure 21 shows the sensor's CO sensitivity characteristics before and after the dust exposure test. This data demonstrates that the dust test of UL2034, Sec. 53 has a negligible effect on CO sensitivity.4-9 Water loss testF or evaluating the life expectancy of TGS5042 from the viewpoint of its water reservoir (which prevents the electrolyte from drying up), the weight loss of TGS5042 was periodically measured when stored at 20˚C/40%RH and 70˚C/5%RH respectively. F igure 22 demonstrates that the sensor’s weight decreased linearly with time due to evaporation of the water. The rate of water loss under various temperature was related with the water vapor pressure at each temperature. According to calculations based on this rate of water loss and the differences in water vapor pressure in 20˚C and 70˚C, the water (>4.5g initially) will last more than 10 years under natural residential conditions such as 20˚C/40%RH.5. MarkingThe TGS5042 comes with a sticker attached to the sensor housing which contains important information. The one dimensional bar code indicates the sensor's sensitivity (slope) in numeric value as determined by measuring the sensor's output in 300ppm of CO:xxxx = x.xxx nA/ppmIn user readable format, the sensor's sensitivity per ppm (nA) is printed below the one dimensional bar code and the sensor's Lot Number is printed to the left of the sensitivity data. Please note that three decimal places should be added to the sensitivity reading (e.g. 1827 should be read as 1.827 nA/ppm).-0.10-0.08-0.06-0.04-0.020.00020*********Time (days)Figure 22 - Water loss testFigure 21 - Dust test1827Sensitivity to CO (nA/ppm)FIGAROTGS5042(Ex.1827 = 1.827nA/ ppm)Figure 23 - TGS5042 markings(NOTE:UL Mark may appear on shrink tube)6. Cautions6-1 Situations which must be avoided1) Disassembling the sensorUnder no circumstances should the sensor be disassem-bled, nor should the sensor can and/or cap be deformed.2) Contamination by alkaline metalsSensor characteristics may be significantly changed when the sensor is contaminated by alkaline metals, especially salt water spray.3) Exposure to high concentration of basic (non-acidic) gases Sensor characteristics may be irreversibly changed by the exposure to high concentrations of basic gases such as ammonia.4) High temperature exposureAt temperatures of 80˚C or higher, the sensing membrane may deteriorate, resulting in irreversible change of sensor characteristics.5) Contact with waterSensor characteristics may be changed due to soaking or splashing the sensor with water.6) Application of excessive voltageIf higher than specified voltage is applied to the sensor, breakage may occur or sensor characteristics may drift, even if no physical damage or breakage occurs. Do not use the sensor once excessive voltage is applied.6-2 Situations to avoid whenever possible1) Exposure to silicone vaporsAvoid exposure of sensor where silicone adhesives, hair grooming materials, or silicone rubber/putty may be present. Silicone vapors may cause clogging of the gas diffusion route.2) Dew condensationIf severe dew condensation occurs for a long period inside of the sensor or on the sensor surface, it may cause clogging of gas diffusion route or deterioration of the sensing membrane. Mild dew condensation which occurs in normal indoor air would not cause any significant damage.3) Storage in sealed containerDo not keep the sensor in a sealed containers such as sealed bag. Due to ambient temperature change, dew condensation may occur inside the sensor if the sensor is stored in this manner.4) FreezingWhen subjected to temperatures below 0˚C, it is possible that the water in the reservoir may freeze. Since water volume will expand when freezing, the sensor can may undergo some deformation. Care should be taken in the design of the detector to ensure that the sensor is not placed too close to other components or the circuit pattern on a PCB, as such deformation may cause the sensor to come in contact with these items. In addition, if the freezing process were to occur very rapidly, the sensor will undergo irreversible change in its characteristics. To avoid this risk, it is recommended that the sensor be positioned with the cap (working electrode) facing up (for more information, refer to Item 3-1 Position Dependency of the Sensor in the document Application Notes for TGS5042).5) Exposure to hydrogen sulfide or sulfuric acid gasIf the sensor is exposed to hydrogen sulfide or sulfuric acid gas, sensor components such as the gas diffusion film, can, and cap may be corroded, resulting in the sensor damage.6) Vibration and shockVibration and shock may cause an open or short circuit inside the sensor.7) Dust and oil mistExtremely high concentrations of dust or oil mist may cause clogging of the sensor's internal structure. When such conditions are expected to be encountered, installation of an external air filter is recommended.8) Flux for solderingManual soldering is recommended since high concen-trations of flux may affect sensor characteristics when the sensor is soldered by wave soldering. When wave soldering is used, a test should be conducted before production starts to see if there would be any influence to sensor characteristics. Please refer to Item 5-3 of Application Notes for TGS5042 for advice on manual soldering conditions. 9) Exposure to organic vaporsIf the sensor is exposed to organic vapors such as alcohols, acetone, or volatile oils, these gases may adsorb on the sensor surface, resulting in temporary sensor drift.6-3 Additional cautions for installationThis sensor requires the existence of oxygen in the operating environment to function properly and to exhibit the characteristics described in this brochure. The sensor will not operate properly in a zero oxygen environment. Figaro USA Inc. and the manufacturer, Figaro Engineering Inc.
