DIAGNOSTIC TESTS FOR THE INTELLIGENT GAS SENSORS, iSERIESTechnical NoteHoneywell introduces the Next-Generationintelligent (iseries) gas sensors. These sensorshave a digital interface, longer life andnumerous built-in diagnostics features.The iseries’ intelligent diagnostic features help enhance the overall instrumentperformance, making them smarter and safer by indicating faults and monitoringhealth, thereby decreasing downtime and cost of ownership.The purpose of this document is to describe the Predictive Calibration and End-of-lifefunctions, and outline the principles of the diagnostic tests.BACKGROUNDAll gas sensors drift over time and eventually need recalibrating, and the amountof drift is strongly dependent on the environment that the sensor is used in.Traditionally, instrument developers, fleet managers or end users would work out forthemselves by experience how often they need to recalibrate sensors, or would use recommendations from the sensor or instrument manufacturer as it is not knownwhat conditions the sensors are being used in. This often results in unnecessarilyfrequent recalibrations which is costly and time consuming.Intelligent FeaturesThe iseries platform uses internal tests to monitor the condition of the sensorand apply algorithms both to compensate for drift and to predict when the sensoraccuracy exceeds a predefined limit and needs recalibrating.It can also predict when it is wearing out and can give warning in advance that thesensor needs replacing. As both the Predictive Calibration and End-of-life indicationuse predictions based on the environment that the sensor is being used.Definition of Diagnostic TestsPredictive Calibration: The calibration process can be very tedious, costly and a time-consuming process. With this function, sensors can predict in advance whenits accuracy is becoming too poor to give a reliable reading. This function helps to identify exactly when a recalibration is required.The sensor can estimate the time to recalibration up to six months in advance. Recalibration intervals will be typically at least twice as long as for conventional sensors and will adapt depending on the environment – with sensors used in more benign environments needing less frequent calibrations than those in aggressive ones.The user can configure the accuracy limit of the sensor, and this will determine the interval at which the calibration is needed. In other words, the tighter the accuracy value, the more frequent calibration needed.The user can therefore trade off accuracy against recalibration interval. There is also a configurable built in fixed interval recalibration countdown timer for applications where legislation requires calibration at certain intervals.End-of-Life: The lifespan of a sensor depends mostly on the environmental conditions at which the sensor is exposed. With this function, the sensor can predict in advance when its sensitivity is falling too low to give a reliable and accurate reading. When the End-of-life function is triggered, the sensor automatically warns the instrument via a set of fault flags sent together with the gas reading. If the fault is detected the instrument can warn the user to stop using the sensor.How was the design of the sensor optimised?Honeywell engineers performed finite element analysis of the water management and electrolyte distribution within sensors and gained an extensive understandingof the optimum designs for retaining the electrolyte in the right place at the right concentration.Subsequently, safety operating area charts were developed based on a combination of fundamental physical theory, modelling and experimental verification to show how sensors will perform and withstand over the full temperature, humidity and time.To validate that the sensor will last in real-world applications, an environmental database was obtained. The database contains hundreds of locations around the world, with temperature and humidity data for 10 years with two hourly resolution. The knowledge of use cases for sensors was combined, for example time spent indoors and outdoors, charging to provide input data on the actual conditionssensors are exposed to in the real world. This information was fed into the models to predict how long sensors will last and how their performance will change in real world conditions, and to assist us in optimising the sensor design for maximum performance and life.The environmental performance data was generated by storing sensors in a rangeof environmental conditions over a two-year period. There were more than 8000 individual gas responses recorded for each gas typeDuring this period, the sensors were tested to generate different databases corresponding to the performance of the sensor at particular environments.The resulting predictive algorithm keeps track of the electrolyte concentration and environmental conditions over time and extrapolates this data with a linear regression in order to accurately predict when does the sensor need to be calibrated or when does the sensor is about to reach its lifespan.How does the predictive model for EoL and Predictive Calibration works?To estimate the EoL and Predictive Calibration, a 30-day time period is defined. During this period, the sensor will keep track of the environmental changes. The model works under the assumption that the sensor will be exposed to similar conditions.For instance, if the sensor has been in an extremely hot and dry environment, the predicted model will calculate the corresponding water loss as if the conditions remained the same; giving warning to the user in order to prevent further dry out. Figure 1 shows how the electrolyte concentration and predicted electrolyte concentration vary for a sensor in an extreme environment. The environment chosen corresponds to a challenging environment for the sensor to survive: during winter, outdoor temperatures can be -40°C or less, and in a heated unhumidified buildingor car, the relative humidity can be extremely low due to the very low water content of the cold outside air. Therefore, a sensor which spends part of the day indoors and part outdoors (a typical ‘field worker’ use case) not only gets very dry in winter but is also expected to function at very low temperatures.A perfect prediction (theoretical) would follow the dashed black line. In other words, the predicted days to recalibration would be exactly equal to the actual days to recalibration.The solid black line shows the true electrolyte concentration, which gets dry (high concentration) each winter but recovers to some extent each summer. The yellow line shows how the concentration has been predicted. The historical relative humidityis calculated from the average of another 30 days prior to that. As the prediction is made over a longer time, it becomes less accurate, mainly because the historical environmental conditions become less representative of the future conditions. How often does the sensor updates the EoL and Predictive Calibration?The diagnostic test runs automatically every 24 hours. However, the test is only performed when the sensor is in sleep mode, so it is highly recommended to change the sensor to sleep mode whenever it is not in use (otherwise the End of Life and Predictive Calibration estimations will not be updated/recalculated, leading to non-accurate results).The sensor needs to be in sleep mode at least two minutes per day, so it can update the EoL and Predictive Calibration values.What technique is used for the diagnostic tests?For this test, a smart indicative gadget is used as a diagnostic electrode. Thenan electrochemical technique called square wave voltammetry is applied to the electrode.The technique is a linear potential sweep voltammetry that uses a combined staircase potential and a square wave, which has the advantage of having better peak definition and location than conventional cyclic voltammetry or staircase voltammetry.The diagnostic test is performed to determine the electrolyte concentration of the sensor.Figure 2. Diagnostic TestingHow and when the End-of-Life and Predictive Calibration are flagged?The error and faults can be transmitted to the instrument every time it requests a gas reading from the sensor. For additional information about the gas reading format consult get data pack command (0x30) in the User’s Manual.Predictive Calibration alarm consists of two different parameters, and the • Thealarm will be triggered when either the countdown or the accuracy threshold are reached (whichever is triggered first):o The Predictive Calibration estimation will depend on the requested accuracy of the sensor. This parameter can be configured by the user: the tighter theaccuracy value, the more frequently the calibration.o Additionally, a countdown timer can be set by the user. This period can reflect the time required to calibrate the sensor, which may vary depending on thespecified standard or applications.• Likewise, the End-of-life is flagged when either the countdown or the future prediction algorithm conditions are met (whichever is triggered first):o The predicted End-of-Life algorithm is flagged when the sensor detects less than 50% of its initial sensitivity or when the electrolyte concentrationis above or below its limit. The sensitivity estimation is constantly updatedand its calculation is based on the measure at the minimum temperatures atwhich the sensor has been exposed to.o Along with this, there is a five-year countdown timer. The alarm is flagged after the sensor has reached its expected lifespan.How accurate are the End-of-life andPredictive Calibration functions?The predictive model for End-of-life and time to calibrationis highly accurate if the environmental conditions remainadequately constant.An analogy to this is the ETA (estimated time to arrival) in a car’s GPS system, which is based on previous average speed. If you travel at a constant speed, the ETA will count down linearly and be quite accurate over long distances. However, if you speed up or slow down the ETA could increase of decrease significantly throughout the journey. Similarly, if a sensor is kept in constant conditions, the future prediction based on historical conditions should predict a long way into the future quite accurately, and as a result the time to end of life or recalibration would decrease linearly over time. If the sensor is put into a more aggressive environment, then its predicted time to EOL/ recalibration will start to drop rapidly, whereas if a sensor that has been running in aggressive (e.g. dry) conditions is transferred to more benign conditions, the time to end of life or recalibration prediction may even increase over time.Other diagnostic tests:Just like the End-of-life and Predictive Calibration flags, the sensor can warn the instrument about other possible errors and failures that may appear on a sensor whenever a gas reading command is requested. These flags could also be used to indicate to the end user what type of maintenance is required, for example if the sensor warns that its electrolyte is getting too dry or wet the instrument could advise the user to store it in a suitable humidity environment to recover it.The following table shows the possible failures that the sensor may encounter along with their corresponding automatic detection methods:002717-2-EN | 2 | 08/21HoneywellAdvanced Sensing Technologies 830 East Arapaho Road Richardson, TX 75081FOR MORE INFORMATIONHoneywell Advanced Sensing Technol-ogies services its customers through a worldwide network of sales offices and distributors.

MAINTENANCESCREENSCREENSENSORWiring connections are:-The unit requires a nominal 18 to 30V, 30m current-loop-powered supply.First zero the control system with no gas present on the sensor. If target gas is suspected to be in the vicinity of Sensepoint, flow clean air over the sensor using a flow housing (see below).Fit a flow housing and connect a cylinder of either air, for a zero, or a known concentration of gas (approximately 50% FSD) to the flow housing using nylon or PTFE tubing. Tubing lengths should be kept to a minimum to avoidextending the speed of response. Connect the outlet of the flow housing to a safe exhaust area. Pass the gas through the flow housing at a flow rate of approximately1 l to 1.5 l per minute. Allow the sensor to stabilise. When gassing with air, adjust the control card to indicate zero. For span, the control card should be adjusted to indicate the concentration of the target gas being applied. Remove the flow housing and the gas supply.Note: for oxygen, the span gas is normally air at 20.8%v/vO 2. The control card should be adjusted to indicate this when the sensor is in either clean ambient air, or in a flow of 20.8%v/v O 2 in nitrogen from a cylinder. A zero adjustment is not normally required, however it is recommended that the alarm levels are tested using a cylinder of a lower concentration of oxygen in nitrogen.See Table 1 for details of concentrations and times to be used. If the controller cannot be spanned, consult the technical handbook.For calibration using the Weather Protection in high flow applications refer to the technical handbook.Plastic retainerExternal hydrophobic barrier Main body of sensorOxygen cellInternalhydrophobic assembly Sensor cap Toxicelectrochemical cellRFI screen / metal gauze11.

SENSOR MOUNTING FOR USE WITH THE INTELLIGENT GAS SENSORS, iSERIES Application NoteContentsTurret Sealing 1PCB Mounting 2Recommended Spring Contact 2Flow Rate 3Minimum Flow Rate 3Recommended Design 4Turret Sealing: IP68 DesignThe front of the sensor is fit enough to withstand dust, sand, and dirt, along withbeing resistant to submersion up to a maximum depth of 1,5 m underwater for up tothirty minutes if the sensor is mounted using the recommended turret seal design.The O-ring around the sensor allows the user to seal the sensor and attain the IP68rating. Note that the rear of the sensor is not water-proof.The recommended turret dimensions for the bore diameter are from 17,56 mm (min)to 17,76 mm (max), and the surface finish must be longer than 3 mm, as depicted inFigure 1.Figure 1. iseries Sensor (Recommended Turret Dimensions)PCB MountingIf the sensor is mounted inside an instrument, it is required to allow a minimum space height under the cell; this height will depend on the connector. Depending on which of connector is used, the minimum height between the cell and PCB would change. Figure 2. iseries Sensor (Mounted Inside an Instrument)If the sensor is installed inside an instrument, the airpath of the gas is different to access the sensor; likewise, if an additional membrane is used on top of the sensor, the gas diffusion would be different. In general, if the gas dynamics change, the measured concentration value would also change. To compensate for this, it is necessary to change the user factor accordingly.The sensor/instrument coupling can be analysed by Honeywell, so the user factor can be determined accordingly. This would mean that once the user factor is assigned, the sensor would be ready to be set in your instrument (fully calibrated).AØ 17,76D e p e n d a n t o n Recommended spacer to prevent over compression of spring contact: Surface mount resistor size 1206Recommended PCB spring contact:ITT Cannon120220-0310(shown)A-A (1:1)BRecommended Spring ContactUnder no circumstances should intelligent sensor pads be soldered to, as this can cause leakage of electrolyte.

The minimum flow which is required will be different depending on the sensor type.The reaction mechanism of sensors, consumes target gas - this means that the concentration of target gas will be depleted immediately in front of the sensor.The minimum flow rates are set so that, the sensor is exposed to a constant concentration of target gas - the flow rate is great enough to ensure that this depleted concentration is immediately replaced. This mimics the situation where the sample diffuses to the sensor; there will be a large volume of target gas so that the depletion is immediately replaced - via diffusion.Figure 3.ITT Spring Contact: 120220-0348002738-1-EN | 1 | 08/21HoneywellAdvanced Sensing Technologies 830 East Arapaho Road Richardson, TX 75081FOR MORE INFORMATIONHoneywell Advanced Sensing Technol-ogies services its customers through a worldwide network of sales offices and distributors.

Technical NoteSPI Communication with Honeywell Digital Output Pressure SensorsSensing and Control1.0 IntroductionThe Serial Peripheral Interface (SPI) is a simple bus system for synchronous serial communication between one master and one or more slaves. It operates either in full-duplex or half-duplex mode, allowing communication to happen in either both directions simultaneously, or in only one direction. The master device initiates an information transfer on the bus and generates clock and control signals. Slave devices arecontrolled by the master through individual slave select lines and are active only when selected.Honeywell pressure sensors with SPI output operate in half-duplex mode only, with data transfer from the slave to the master (Figure 1). For this data transmission three lines need to be used:1. Slave Select (SS)2. Signal Clock (SCLK)3. Master In - Slave Out (MISO)These three bus lines are all unidirectional. SCLK and SS and are controlled by the master while MISO is controlled by the slave.2.0 Data Transfer with SPI Output Pressure SensorsStarting communication with Honeywell SPI output pressure sensors begins by deasserting the SS line. At this point, the sensor is no longer idle, and will begin sending data once a clock is received.Honeywell digital output pressure sensors are configured for operation such that data on the MISO line will transition during the falling edge of clock pulses. This means that the data on MISO should be sampled by the master device during the rising edge of the clock pulse.Figure 2 shows an example of a 1 byte data transfer from the slave to the master. In this example, the data 101 (01100101 binary, or 65 hex) would be the result of the read.Figure 2. Example of a 1 Byte SPI Data Transfer withOnce the clocking begins, Honeywell digital output pressure sensors are designed to output up to 4 bytes of data, depending on the sensor options and the needs of the application. In all cases, the first two data bytes are thecompensated pressure output, along with sensor status bits. The third and fourth bytes are for optional compensated temperature output.2.1 Pressure ReadingTo read out a compensated pressure reading, the master generates the necessary clock signal after activating thesensor with the slave select line. The sensor will transmit up to 4 bytes of data – the first two bytes containing thecompensated pressure output, and the second two bytescontaining the optional compensated temperature output. The master can terminate the communication by stopping the clock and deactivating the slave select line. Examples of the communication are shown in Figure 3.SPI Communication with Honeywell Digital Output Pressure Sensors2 Honeywell Sensing and Controlbytes of data. The information contained in these bytes is non-corrected data, and should not be used.2.2 Temperature ReadingThe optional corrected temperature data can be read out with either 8 bit or 11 bit resolution. By reading out the third byte of data from the sensor, the 8 bit compensated temperature value can be read. Further, by reading out the fourth byte of data, the complete 11 bit optional compensated temperature value can be read. The 8 bit value gives an approximate 0.8 ºC resolution, while the 11 bit value gives an approximate 0.1 ºC resolution.When reading the full 11 bit resolution temperature output, the 5 least significant bits of the fourth data byte are “Do Not Care ” and should be ignored.2.3 Status BitsHoneywell digital output pressure sensors offer both standard and optional diagnostics to ensure robust system operation in critical applications. The diagnostic states are indicated by the first two Most Significant Bits of data byte 1.Four diagnostic states are indicated by the 2 status bits (Table 1).This mode should not be seen during normal operation.Standard diagnostics for Honeywell digital output pressure sensors consists of an EEPROM (Electrically ErasableProgrammable Read-Only Memory) signature used to validate the EEPROM contents during startup. In the event that any EEPROM contents change after calibration, a diagnostic condition will be flagged.Optional diagnostics for Honeywell digital output pressure sensors consist of:Loss of sense element connection Short circuit of sense elementSPI Communication with Honeywell Digital Output Pressure SensorsHoneywell Sensing and Control 3When the two status bits are “11”, one of the above mentioned diagnostic faults is indicated.When the status bits read “10”, “s tale” data is indicated , this means that the data that already exists in the sensor’s output buffer has already been fetched by the master, and has not yet been updated with the next data from the current measurement cycle. This can happen when the master polls the data quicker than the sensor can update the output buffer.(Please contact Honeywell Customer Service with questions regarding the availability of optional digital output pressure sensor diagnostics.)3. 0 Calculation of the Pressure from the Digital OutputFor Honeywell digital output pressure sensors, the output of the device can be expressed by the transfer function of the device as shown in Equation 1.Equation 1: Pressure Sensor Transfer Function Output (OutputRearranging this equation to solve for Pressure, we get Equation 2:Equation 2: Pressure Output Function max Pressure (Output (Pressure (OutputWhere:Output max = output at max. pressure [counts] Output min = output at min. pressure [counts]Pressure max = max. value of pressure range [bar, psi, kPa, etc.] Pressure min = min. value of pressure range [bar, psi, kPa, etc.] Pressure = pressure reading [bar, psi, kPa, etc.] Output = digital pressure reading [counts]As an example, the pressure will be calculated for a -1 psi to 1 psi differential sensor with a 10% to 90% calibration and a pressure output of 1657 (decimal) counts:Output max = 14745 counts (90% of 214counts or 0x3999)Output min = 1638 counts (10% of 214counts or 0x0666) Pressuremax= 1 psiPressure min = -1 psiPressure = pressure in psi Output = 1657 counts)1()163814745())1(1()16381657(Pressure)1(13107)2()19(Pressure )1(1310738Pressure)1()002899.0(Pressure997.0Pressure psi 4.0 Calculation of Optional Temperature from the Digital OutputFor Honeywell digital output pressure sensors with the optional compensated temperature output, the output can be converted to degrees C using Equation 3:Equation 3: Temperature Conversion Function 50200Output C)(If the 8 bit temperature output is used, the data must first be shifted left by 3 bits and have the 3 Least Significant Bits set to “0’s ” for the equation to work.As an example, the optional compensated temperature output will be calculated for a sensor with an 8 bit temperature output of 255:Step 1: Left shift the above 8-bit value by 3 places and append the 3 LSBs with 0s:Digital Temperature Output (8 – bit) = 255 = 11111111b 11111111000b = 2040Step 2: Use the adjusted value and plug into Equation 3:5020020472040e Temperatur149.31 e Temperatur ºCAs a second example, the optional compensated temperature output will be calculated for a sensor with an 11 bit temperature output of 1456:Step 1: Plug the digital temperature output value into Equation 3:5020020471456e Temperatur26.92 e Temperatur ºCSPI Communication with Honeywell Digital Output Pressure SensorsSensing and ControlHoneywell1985 Douglas Drive NorthGolden Valley, MN 55422 /sensing 008202-3-ENMay 2012Copyright © 2012 Honeywell International Inc.
