TGS2602 空气污染、臭味检测用特点： 应用：・低功耗 ・空气清新机、换气扇控制 ・对VOC 、氨气、硫化氢有高灵敏度 ・脱臭器控制・长寿命、低成本 ・室内空气监视器・可利用简单电路下图是典型的香烟烟雾灵感度特性。

香烟的根数是约10平米的房间吸烟情况下的数值。

这里的纵轴也用传感器电阻比Rs/Rs(Air)来表示， 这里的Rs ､Rs(Air)定义如下： Rs ＝香烟的烟雾存在时的传感器电阻值 Rs(Air) ＝清洁大气中的传感器电阻值 香烟灵敏度特性：敏感素子由集成的加热器以及在氧化铝基板上形成的金属氧化物半导体构成。

FIGARO CANNOT ASSUME ANY RESPONSIBILITY FOR ANY USE OF ITS SENSORS IN A PRODUCT OR APPLICATION FOR WHICH A SENSOR HAS NOT BEEN SPECIFICALLY TESTED BY FIGARO.Both TGS2611-C00 and -E00 are UL recognized components in accordance with the requirements of component recognition testing has confirmed long term stability in 60ppm of methane; other characteristics shown in this brochure have not been confirmed by UL as part of component recognition.TGS2611 is available in two different models with different external housings but identical sensitivity to methane gas. TGS2611-C00 possesses small size and quick gas response, making it suitable for gas leakage checkers, while TGS2611-E00 uses filter material in its housing to eliminate the influence of interference gases such as alcohol, resulting in highly selective response to methane gas. Both models are capable of meeting the requirements of EN50194 and UL1484.1. Specifications1-1 Features*High selectivity to methane*Low power consumption*Small size*Long life and low cost*Uses simple electrical circuit1-2 Applications* Residential gas alarms* Portable gas detectors* Gas leak detectors for gas appliances1-3 StructureFigure 1 shows the structure of TGS2611. Using thick film techniques, the sensing material (SnO2) is printed on electrodes (noble metal) which have been printed onto an alumina substrate. One electrode is connected to pin No.2 and the other is connected to pin No.3. The sensor element is heated by RuO2 material printed onto the reverse side of the substrate and connected to pins No.1 and No.4.Lead wires are Pt-W alloy and are connected to sensor pins which are made of Ni-plated Ni-Fe 50%.The sensor base is made of Ni-plated steel. The caps of both TGS2611-C00 and TGS2611-E00 are stainless steel. The upper opening in both caps is covered with a double layer of 100 mesh stainless steel gauze (SUS316). The TGS2611-E00 utilizes a charcoal filter inside the cap for reducing the influence of interference gases.1-4 Basic measuring circuitFigure 2 shows the basic measuring circuit. Circuit voltage (Vc) is applied across the sensor element which has a resistance (Rs) between the sensor’s two electrodes and the load resistor (R L) connected in series. When DC is used for Vc, the polarity shown in Figure 2 must be maintained. The Vc may be applied intermittently. The sensor signal (V RL) is measured indirectly as a change in voltage across the R L. The Rs is obtained from the formula shown at the right.Fig. 1 - Sensor structureVc - V RLV RLRs = x R LFormula to determine RsFig. 2 - Basic measuring circuitNOTE: In the case of V H, there is no polarity, so pins 1 and 4 can be considered interchangeable. However, in the case of V C, when used with DC power, pins 2 and 3 must be used as shown in theFigure above.TGS2611-E00Sensingelement1-5 Circuit & operating conditionsThe ratings shown below should be maintained at all times to insure stable sensor performance:1-6 Specifications NOTE 1Mechanical Strength:The sensor shall have no abnormal findings in its structure and shall satisfy the above electrical specifications after the following performance tests:Withdrawal Force - (pin from base) Vibration - Shock -withstand force of 5kg in each directionfrequency-1000cycles/min.,total amplitude-4mm, duration-one hour, direction-verticalacceleration-100G, repeated 5timesNOTE 1: Sensitivity characteristics are obtained under the following standard test conditions:(Standard test conditions)Temperature and humidity: 20 ± 2˚C, 65 ± 5% RH Circuit conditions:Vc = 5.0±0.01V DCV H = 5.0±0.05V DC R L = 10.0k Ω ± 1%Preheating period: 7 days or more under standard circuit conditions.1-7 DimensionsFig. 3 - Sensor dimensionsAll sensor characteristics shown in this brochure represent typical characteristics.Actual characteristics vary from sensor to sensor and from production lot to production lot.

NOTE:calibration is required for each sensor (for Toxic and Explosive Gas Leak Detectors’).under various ambient conditionsTable 1 - Temperature and humidity dependency(typical values of Rs/Ro for Fig. 6)Table 1 shows a table of values of the sensor’s resistance ratio (Rs/Ro) under the same conditions as those used to generate Figure 6.Figure 7 shows the sensitivity curve for TGS2611 to methane under several ambient conditions. While temperature may have a large influence on absolute Rs values, this chart illustrates the fact that effect on the slope of sensor resistance ratio (Rs/Ro) is not significant. As a result, the effects of temperature on the sensor can easily be compensated.For economical circuit design, a thermistor can be incorporated to compensate for temperature (for additional information on temperature compensation in circuit designs, please refer to the Technical Advisory ‘Technical Information on Usage of TGS Sensors for Toxic and Explosive Gas Leak Detectors’).2-3 Heater voltage dependencyratio according to variations in heater voltage (V typical characteristics shown in this brochure.2-4 Cautions on sensor power consumptionFigure 9relationship is referred to as V-I characteristics.basic measuring circuit (see Figure 2and can be calculated according as follows:Ps =where :R L : Load resistor value (k Ω)V RL : Sensor output voltage (v)Vc : Circuit voltage (v)Ps : Power consumption (mW)Vc 2/(4 x R L damage to the sensor due to Joule heat.minimum R L voltage.Table 2 - Minimum suggested R L valuesV RL x (Vc-V RL )R L2-7 Long-term characteristics3000ppm of ethanol.were powered under standard test conditions. 1000ppm of iso-butane.to a stable level within three days of energizing.As the charts presented in this section illustrate, the sensor shows stable long term characteristics.3. Reliability3-1 Corrosion testFigure 15 shows the effect on TGS2611 of corrosivegases specified in Item 43.15 of the UL 1484 standard.Sensor resistance prior to corrosive gas exposure wasmeasured. Unenergized sensors were then placedinto an environment of 23˚±2˚C and 95%RH. In thisenvironment, two separate tests were conducted: onein 0.1% H2S, the other in a combination of 0.5% SO2and 1.0% CO2, with each test exposure lasting 10days. After this exposure, the sensor was re-energized in normal air prior to measuring sensorresistance after removal from corrosive gases.As this data would suggest, sensor characteristics aretemporarily influenced by exposure to corrosive gasconcentrations specified by Sec. 43.15 of UL 1484,TGS2611 has been successfully tested against theignition test requirements of the UL1484 standard.The sensor did not initiate ignition of a propaneFigure 16 shows how the sensor signal (V RL) isaffected by air flow. The test procedure involvessituating the sensor in an air stream of 3.1 meters persecond, with the air flow vertical/horizontal to theflameproof stainless steel double gauze of theThe decrease in sensor signal shown in Figure 16resulted from the decrease in sensor elementtemperature caused by the air flow. As a result, directFig. 16 - Effect of air flow on TGS2611-C00Fig. 17 - Test procedure for heater durability3-4 Heater resistance durabilityFigure 17 illustrates the procedure for testing the effects of excess voltage applied to the heater. Heater resistance was measured while the heater was unpowered and at room temperature.The results of this test are shown in Figure 18 which shows the change in resistance of the heater when various heater voltages (rather than the standard 5.0V) are applied in the absence of gases.As this section demonstrates, the heater shows good durability against increased heater voltage.However, since excessive heater voltage will cause the sensor’s heater resistance to drift upwards,excessive heater voltage should still be avoided.standard circuit conditions. After returning the sensorexposure as shown in Figure 20.The result of the above test is shown in Fig. 20. A 10% iso-butane exposure for 60 seconds appears to cause an increase in Rs in gas. Furthermore, sensor to its original value after energizing in normal air.may cause a permanent change in the sensor’sdone, it must be carefully administered to avoid sensor damage.NOTE: To achieve the optimal level of accuracy in gas detectors, each TGS2611 sensor should be individually calibrated by matching it with a load resistor (R L) in an environment containing the target gas concentration for alarming (refer to Fig. 2).For the convenience of users, TGS2611 is classified into 24 groups according to the each sensor’s Rs in methane. ID numbers marked on the sensor’s body indicate the sensor’s grouping. Individual sensor calibration can be eliminated by matching the sensor with the recommended R L for each sensor ID. However, because group calibration is used instead of individual calibration, an average of 10% less accuracy would result for detectors using group calibration. Please refer to “Application Notes for TGS2611” for more information.4 Cautions on Usage of Figaro Gas Sensors4-1 Situations which must be avoided1) Exposure to silicone vaporsIf silicone vapors adsorb onto the sensor’s surface, the sensing material will be coated, irreversibly inhibiting sensitivity. Avoid exposure where silicone adhesives, hair grooming materials, or silicone rubber/putty may be present.2) Highly corrosive environmentHigh density exposure to corrosive materials such heater material.3) Contamination by alkaline metalsSensor drift may occur when the sensor is contaminated by alkaline metals, especially salt water spray.4) Contact with waterSensor drift may occur due to soaking or splashing the sensor with water.5) FreezingIf water freezes on the sensing surface, the sensing material would crack, altering characteristics.6) Application of excessive voltageIf higher than specified voltage is applied to the sensor or the heater, lead wires and/or the heater may be damaged or sensor characteristics may drift, even if no physical damage or breakage occurs. 7) Operation in zero/low oxygen environment TGS sensors require the presence of around 21% (ambient) oxygen in their operating environment in order to function properly and to exhibit characteristics described in Figaro’s product literature. TGS sensors cannot properly operate in a zero or low oxygen content atmosphere.8) Excessive exposure to alcoholIF TGS2611-E00 is exposed to high concentrations of alcohol (such as 10,000ppm or more) for a long period of time, the filter may become saturated. In this case,Figaro USA Inc. and the manufacturer, Figaro Engineering Inc. (together referred to as Figaro)reserve the right to make changes without notice to any products herein to improve reliability,functioning or design. Information contained in this document is believed to be reliable. However, Figaro does not assume any liability arising out of the application or use of any product or circuit describedherein; neither does it convey any license under its patent rights, nor the rights of others.Figaro's products are not authorized for use as critical components in life support applications wherein a failure or malfunction of the products may result in injury or threat to life.the sensor would show a lower resistance in alcohol than that indicated in Figure 4a.4-2 Situations to be avoided whenever possible 1) Water condensationLight condensation under conditions of indoor usage should not pose a problem for sensor performance.However, if water condenses on the sensor’s surface and remains for an extended period, sensor characteristics may drift.2) Usage in high density of gasSensor performance may be affected if exposed to a high density of gas for a long period of time,regardless of the powering condition.3) Storage for extended periodsWhen stored without powering for a long period, the sensor may show a reversible drift in resistance according to the environment in which it was stored.The sensor should be stored in a sealed bag containing clean air; do not use silica gel. Note that as unpowered storage becomes longer, a longer preheating period is required to stabilize the sensor before usage .4) Long term exposure in adverse environmentRegardless of powering condition, if the sensor is exposed in extreme conditions such as very highhumidity, extreme temperatures, or high contamination levels for a long period of time, sensor performance will be adversely affected.5) VibrationExcessive vibration may cause the sensor or lead wires to resonate and break. Usage of compressed air drivers/ultrasonic welders on assembly lines may generate such vibration, so please check this matter.6) ShockBreakage of lead wires may occur if the sensor is subjected to a strong shock.7) SolderingIdeally, sensors should be soldered manually.However, wave soldering can be done under the following conditions:a) Suggested flux: rosin flux with minimal chlorine b) Speed: 1-2 meters/min.c) Preheating temperature: 100±20˚C d) Solder temperature: 250±10˚Ce) Up to two passes through wave soldering machine allowedResults of wave soldering cannot be guaranteed if con-ducted outside the above guidelines since some flux vapors may cause drift in sensor performance similar to the effects of silicone vapors.。

A wide range of 350~50,000ppm of carbon dioxide can be detected by TGS4160, making it ideal for usage in a variety of applications.The CO 2 sensitive element consists of a solid electrolyte formed between two electrodes, together with a printed heater (Pt) substrate. By monitoring the change in electromotive force (EMF) generated between the two electrodes, it is possible to measure CO 2 gas concentration.Adsorbent (zeolite) is filled between the internal cover and the outer cover for the purpose of reducing the influence of interference gases.TGS4160 exhibits a linear relationship between ∆EMF and CO 2 gas concentration on a logarithmic scale.

The heater voltage is applied to the integrated heater in order to maintain the sensing element at a specific temperature which is optimal for sensing. Electromotive force (EMF)of the sensor should be measured using a high impedance (> 100 G Ω) operation-al amplifier with bias current < 1pA (e.g.Texas Instruments' model #TLC271).Since the solid electrolyte type sensorSpecifications:functions as a kind of battery, the EMF value itself would drift using this basic measuring circuit. However, the change of EMF value (∆EMF) shows a stable relationship with the change of CO 2concentration. Therefore, in order to obtain an accurate measurement of CO 2, a special microprocessor for signal processing should be used with TGS4160. Figaro can provide a special evaluation sensor module (AM-4) for TGS4160.Sensing Element Structure:Bottom view(u/m = mm)Green DotBottom View (Sensor Element)A: Lead wiresSide view (Sensor Element)B : Pt Heater F : Sealing Glass E : Counter Electrode (Anode)C : Solid ElectrolyteD : Sensing Electrode (Cathode)EMFVHTGS41601364I BIAS < typ. 1pAGND25ThermistorThermistorOperational amplifier +-深圳市深国安电子科技有限公司地址：广东省深圳市龙华新区牛栏前大厦Ｃ５０７ 网址：ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ ｗｗｗ．ｓｉｎｇｏａｎ．ｃｏｍ．ｃｎ ｗｗｗ．ｓｈｅｎｇｕｏａｎ．ｃｏｍ蒋小姐：１３４　２８７６　２６３１ 电话：８６　７５５－８５２５８９００。
