The time interval required between initial calibration and subsequent recalibrations is dependent on various factors. In strenuous applications involving extremes of operation, or for sensors used in safety applications, frequent instrument calibration may be required. Electrochemical gas sensors need a certain amount of oxygen to function. Generally, a few thousand ppm oxygen is sufficient. However, as calibration normally involves exposing the sensing face of the AQ3 Series gas sensor to gas for a relative short period of time, a calibration gas need not contain oxygen-sufficient oxygen is supplied from the ambient air, for a limited time. In most cases, a five minute exposure time is sufficient to achieve a stable calibration signal.Safety Note : Many AQ3 gas sensors are designed to be used in safety critical applications. To ensure that the sensor and/or instrument in which it is used, is operating properly, it is a requirement that the function of the device is confirmed by exposure to target gas (bump check) before each use of the sensor and/or instrument. Failure to carry out such tests may jeopardize the safety of people and property. Please be aware the recommended flow rate below is for a batch(6 sensor).Figure 10. Calibration SchematicA suitable flow rate is required to ensure accurate calibration – it also means that the response from an AQ3 gas sensors is equivalent in configurations where gas is flowing over the sensor and those where the sample is allowed to diffuse into the sensor. The minimum flow rate whichis required will be different depending on the sensor type – these are shownin the table below. Please be aware therecommended flow rate is for a singlesensor.RECOMMENDED CIRCUITThe recommended circuit for un-biased 4-electrode AQ3 gas sensor is shown below. The description below can be applied to all AQ3 Sensors (unless otherwise noted). The circuit is essentially divided into two parts. The first part is a potentiostat circuit designed to keep the sensor sensing -reference voltage constant. An op amp is used to compare voltage at the reference pin to a stable bias voltage. Any movement of the reference pin voltage is compensated for by adjusting voltage on the counter pin. The circuit should draw no current from the sensor reference pin or the sensor output will be unstable. Further, the offset voltage of this op amp needs to be very low (typically 60 uV to 100 uV) or be nulled out, as offset in the circuit will appear as baseline offset in the sensor / instrument. The second part of the circuit, applied to both sensing and auxiliary pins, is a trans-impedance amplifier (TIA). The job of this circuit is to amplify the small current generated at the sensing pin when gas is detected and convert to a much larger voltage output which can be easily measured by instrumentation. Input is via a small load resistor (R106, R121 in the example circuit), whose value is specified on the sensor datasheet. Gain of this circuit is controlled by the feedback resistor, which is typically 20k to 1M (R107, R122 in the example). The circuit gain should be high enough to give a readable output, but not so high as to saturate the op amp at its highest (overload) output. The circuit below is based on operation from a single rail 5 V op-amp circuit with rail to rail output and a virtual ground reference for the sensor of 2.5 V. The output from the circuit will be positive with respect to virtual ground for sensors measuring oxidizing gases (CO and SO 2) while the op amp output voltage ranges from 2.5 V to 4.5 V (2 V margin). Output will be negative with respect to virtual ground for sensors measuring reducing gases (NO 2 and O 3) while the op amp voltage ranges from 2.5 V to 0 V (2.5 V margin). Please be aware that signals for NO 2 and O 3 sensors are negative when using below circuit, remember to reverse the output signal when you use this circuit in real applications.U100 – This LDO (LP5907 or similar, with low noise and low IQ) is to provide a stable voltage for the circuit. Please refer to chosen LDO datasheet for more detail. U104 – This amplifier act as a trans-im-pedance amplifier (TIA) - current to voltage converter only.U102 – This dual op amp amplifiershould have either a low offset (<100 uV typical) or have its offset nulled out. This amplifier should also have a low power consumption. A suitable op amp is the OPA2336E or similar. This amplifier is used both as potentiostat and a current to voltage converter (trans-impedance amplifier).U101 – The Zener diode circuit is toprovide an accurate and stable reference voltage (2.5 V) to serve as virtual ground., NOTEOther op amp configurations may be used, including single- and dual-supply rails. In this case the reference voltage (bias voltage) will need to change to suit the circuit output range and sensor output, avoiding saturation of the op amp at limits of operation and ensuring a stable bias/virtual ground reference voltage.Figure 11. Recommended Circuitry for 4-electrode AQ3 Gas SensorsCOMPENSATION LOGICS OF AQ3 SERIES SENSORSThis compensation logics provides customers with insights into our air-quality AQ3 Series sensors.AQ3 Series sensors, including AQ3CO, AQ3STF, AQ3ND and AQ3OZ, are specially designed for high-precision and high-accuracy detection of ppb-level CO, SO 2, NO 2 and O 3 in ambient environment. As electrochemical sensors, AQ3 Series are sensitive to the temperature variation, resulting in zero-background current change and sensitivity change that are well-known for long years. Compensation for these changes is indispensable for real-time and high-accuracy monitoring of ppb-level air pollutants. Therefore, in this Characterization Note we are mainly focusing on well-simulated algorithms to make up for these changes, thus enhancing the accuracy and precision of result in the field application.There are four electrodes in AQ3 Series sensors, i.e. sensing electrode, auxiliary electrode, reference electrode and counter electrode. For customers, the signals of sensing electrode and auxiliary electrode are most useful to compensate for zero-background current and sensitivity in practical application. Based on our experiment results, we provide the best-fit compensation algorithms for different kinds of AQ3Series sensors. Some key parameters are explained as below:The table below lists the compensation formula for different sensors, and the tableabove gives the parameters for different sensors.Note:r1 and r2 compensates for the zero-background current change due to temperature variationr3 compensates for the sensitivity change due to temperature variation; r1, r2 and r3 are usually function of temperature /°CCROSS SENSITIVITY TABLEWhilst AQ3 Series gas sensors are designed to be highly specific to the gas they are intended to measure, they will still respond to some degree to various other gases. The table below is not exclusive and other gases not included in the table may still cause a sensor to react.IMPORTANT NOTE: The cross sensitivity data shown below does not form part of the product specification and is supplied for guidance only. Values quoted are based on tests conducted on a small number of sensors and any batch may show significant variation. For the most accurate measurements, an instrument should be calibrated using the gas under investigation.FOR MORE INFORMATIONHoneywell Advanced SensingTechnologies services its customers through a worldwide network of sales offices and distributors.

In fact, this is a thin metal-oxide ﬁlm deposited on a silicon slice. The process of production is similar to the one used for fabricating semiconductors; hence the name metal oxide semiconductor (MOS) for which they are commonly known. Adsorption of the gas on the oxide surface, followed by catalytic oxidation, results in a change of electrical resistance of the oxide material. The surface of the sensor is heated to a constant temperature to speed up the rate of reaction and to reduce the eﬀects of ambient temperature changes. Resistance changes are converted into an electrical signal proportional to the concentration of the gas.Many gases absorb infrared light at certain wavelengths. The absorption spectrum is distinctive for each gas in question. Infrared Open Path and the Point Technology from MSA use electronically-modulated IR radiation sources at two diﬀerent wavelengths. One wavelength is typical for the gas to be measured, while there is no infrared absorption by atmospheric gases for the other wavelength.The signals from both detectors are electronically ampliﬁed and fed into a microprocessor that conditions the signals and produces an output signal proportional to the gas concentration.Electrochemical sensors are typically used to detect toxic gases in the ppm range.Electrodes separated by electro l ytes are enclosed in a small plastic housing and are connected to an external electronic circuit. Gas diﬀuses into the sensor through a permeable membrane and a small current is generated by an electrochemical reaction.Since the rate of gas entry into the sensor is controlled by diﬀusion of the gas through the permeable membrane, the current is proportional to the gas concentration.The measurement principle behind this technology is based on catalytic combustion of the measured gas or vapours in air up to the Lower Explosive Limit (LEL) of the gas. The sensor consists of a pair of matched elements (PELEMENTS), a detector and compensator.The detector comprises a coil of platinum wire inside a small bead of catalytic material.The compensator is similar but does not contain a catalyst and therefore does not respond to gas. Combustible gases are oxidised only on the detector element, where the heat generated increases its resistance, producing a signal proportional to the concentration of combus t ible gas. The compensator helps to compensate for changes in ambient temperature, pressure and humidity which aﬀect both elements equally.ElectrochemicalMOS – Metal Oxide Semiconductor Catalytic CombustionInfrared Absorption5MSA safety .com/detectionThe ultrasonic acoustic gas leak detection technology detects leaks from pressurized gas systems by sensing the airborne ultrasound produced by the escaping gas. This means that the ultrasonic gas leak detectors detect gas leaks at the speed of sound in a detection radius up to 20 meters.Unlike conventional gas detection methods (point or open path gas detection) the ultrasonic gas leak detectors do not have to wait for the gas to accumulate into a potentially dangerous gas cloud and come into physical contact with the detectors. They instantaneously raise an alarm if a leak is detected.The ultrasonic acoustic gas leak detector picks up the leak without being aﬀected by conditions such as changing wind directions, gas dilution, and the direction of the gas leak –conditions relevant for most outdoor gas installations.Most ﬂame detectors identify ﬂames by so-called optical methods like ultraviolet (UV)and infrared (IR) spectroscopy. Flames are generally fueled by hydrocarbons, which, when supplied with oxygen and an ignition source, produce heat, carbon dioxide and other products of combustion. The reaction is characterized by the emission of visible, UV and IR radiation. Flame detectors are designed to detect the absorption of light at speciﬁc wavelengths, allowing them to discriminate between real ﬂames and false alarms.MSA uses ﬂame detectors based on UV/IR or multi-spectrum IR technology. Both technologies are based on line-of-sight detection of the radiation emitted in the UV, visible and IR spectral bands by ﬂames.Photo-acoustic sensor technology was developed by MSA for the detection of toxic or combustible gases at very low concentrations. A gas sample is introduced into the measurement chamber and the sample is exposed to a speciﬁc wavelength of pulsed infrared light. If the sample contains the gas in question, it will absorb an amount of infrared light proportional to the concentration of gas present.The gas molecules heat and cool as they absorb the pulsed infrared energy. The pressure changes result i ng from the heating and cooling of the molecules are measured by a sensitive microphone located inside the photo-acoustic infrared monitor.Flame DetectionUltrasonicPhoto-acousticsCE MARKINGPlacing CE mark declares that product conforms to all applicable directives adopted by the EEA (European Economic Area). Unlike ATEX approval, the manufacturers are responsible for ensuring their product’s conformance to these directives which were developed using IEC and Cenelec standards.ATEXATmosphere EXplosible is French for potentially explosive atmospheres. According to ATEX manufacturer directive 94/9/EC (ATEX 95) and user directive 1999/92/EC (ATEX 137) the electrical safety of all electronic gas detectors and personal monitors used in potentially explosive atmospheres must be tested and marked “ATEX” (EN 60079-0 et seq.).If the gas detection system (detectors and controller) or personal monitor for ﬂammable gases and vapours is used as a safety device “with a measuring function for explosion protection” it must be performance approved by a notiﬁed body in addition to the “ATEX” marking.Performance ApprovalAccording to the ATEX manufacturer directive 94/9/EC and the ATEX user directive 1999/92/EC any gas detection system (detectors and controller) and any personal monitor for ﬂammable gases, if used as safety device to reduce the risk of explosion, has to be performance approved. Performance approval is also required if the oxygen content of the air during inertisation or the concentration of toxic gas needs to be measured.The EC type test certiﬁcate must then show compliance at least to EN 60079-29-1, EN 50104, EN 45544 and EN 50271.Flame detectors are not subject to this performance approval. However, approval in accordance with EN 54-10 can be carried out for these.SIL – Safety Integrity LevelAccording to directives 94/9/EC and 1999/92/EC (ATEX) only certiﬁcation of electrical safety and possibly performance approval are required for gas detection devices. The production of an explosion protection plan for individual existing operating conditions may require measures that go beyond the ATEX requirements to be taken for stationary gas detection devices. The purpose of this additional safety evaluation is to minimise the risk in all applications where erroneous behaviour will result in danger to the safety of persons, the environment and property. Four values are deﬁned as Safety Integrity Levels (SIL). The higher the integrity level, the greater the reliability of a functional circuit. Gas detection devices can only achieve levels SIL1 to SIL3.Products used in safety systems must show a considerably degree of hardware and software reliability so that non-detectable errors can only occur with extremely low probability. The benchmark for this safety-related evaluation of systems is the IEC/EN 61508 standard, which is also used for risk assessment in international process control engineering. This certiﬁcation, which concerns system safety, deﬁnes the requirements of the availability of the safety function and the failure probability of the system that is under examination, as is required in process control engineering.As an application-independent basic standard EN 61508 only describes the general requirements for components and complete systems with safety functions. Therefore it’s inadequate for gas detection devices which also have to fulﬁl other safety criteria. For this reason EN 50271 and EN 50402 for gas detection devicesalso apply in this case.PerformanceApprovalExplosion protection is extremely important when dealing with ﬂammable gases and vapours. The devices and assemblies that are to be used in this area therefore constitute a risk minimisation measure. As electrical equipment, industrial gas detection devices must fulﬁl at least the applicable requirements for operating in potentially explosive areas. Within the European Union, this is regulated by using the relevant harmonised European Directives (94/9/EC and 1999/92/EC).Correspondence with other globally accepted standards must also be ensured during the construction of the electricalequipment.MSA safety .com/detectionMeasuring Range 0–1000 ppm:ACETALDEHYDE, ACRYLONITRILE, AMMONIA, ACROLEIN, 1,3 BUTADIENE, CHLOROFORM, CYCLOPENTANE, 1,2 DICHLOROETHANE, DIETHYL ETHER, DIFLUOROMETHANE, DIMETHYLAMINE, ETHYL ACETATE, ETHYLENE, HEXAFLUOROPROPYLENE, HEXAFLUORO 1,3, BUTADIENE,ISOHEXANE, METHANOL, METHYL FLUORIDE, METHYL IODIDE, MIBK, METHYL METHACRYLATE, METHYLENE CHLORIDE, METHYLENE FLUORIDE, METHYL N-PROPYL KETONE, MONOMETHYLAMINE, NITROGEN TRIFLUORIDE, NITROUS OXIDE, OCTAFLUORO- BUTANE,OCTAFLUOROPROPENE, PENTANE, PERCHLOROETHYLENE, PMVE, PROPANAL, N-PROPANOL, PROPYLENE OXIDE, TETRACHLOR- METHANE,TETRAHYDROFURAN, TETRAFLUOROETHYLENE, 1,1,1 TRICHLOROETHANE, 1,1,2 TRICHLORO -ETHANE, TRICHLOROETHYLENE, TRIETHYLAMINE,VINYL ACETATE, VINYL CHLORIDE, 0-XYLENE, M-XYLENE, P-XYLENE, XYLENES CHILLGARD RT & CHILLGARD M-100 Application TableThe above-mentioned configurations for CHEMGARD, CHILLGARD RT and CHILLGARD M-100 are approved according to CE mark standards.8CHEMGARD Application TableMSA /detection 9IECExThe IECEx Scheme is an international certiﬁcation scheme covering equipment that meet the requirements of international standards; most notably IEC 60079.CSA INTERNATIONALCSA International is an organization that provides performance testing in agreement with national and international standards.
