Methane and Carbon Monoxide Detection

FIGARO PRODUCT INFORMATION TGS 3870 - for the detection of both Methane and Carbon Monoxide Features: * Miniature size and low power consumption * High sensitivity and selectivity to both methane and carbon monoxide (CO) * Low sensitivity to alcohol vapor * Long life and low cost Applications: * Combination methane and carbon monoxide detectors TGS 3870 is Figaro's new metal oxide semiconductor gas sensor for the detection of both methane and carbon monoxide. Using a micro-bead gas sensing structure, both methane and carbon monoxide can be detected with a single sensor element by periodic application of two different heater voltages (high and low). Miniaturization of the gas sensing bead results in a heater power consumption of only 38mW (average). TGS 3870 has low sensitivity to alcohol vapors (a typical interference gas in the residential environment) and has high durability, making the sensor ideal for consumer market gas alarms. The figure below represents typical sensitivity characteristics, all data having been gathered at standard test conditions (see reverse side of this sheet). The Y-axis is indicated as sensor resistance ratio (Rs/Ro) which is defined as follows: Rs = Sensor resistance in displayed gases at various concentrations Ro = Sensor resistance in 3000ppm of methane Sensitivity Characteristics (methane): 100 Methane Hydrogen CO Air The figure below represents typical sensitivity characteristics, all data having been gathered at standard test conditions.
