TGS832

PRODUCT INFORMATION TGS 832 - for the detection of Chlorofluorocarbons (CFC's) Features: * High sensitivity to R-134a * Quick response to R-134a * Improved selectivity * Long term stability * Uses simple electrical circuit * Ceramic base resistant to severe environment Applications: * Refrigerant leak detector The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration. The TGS 832 has high sensitivity to R-134a, the most promising alternative to R12, commonly used in air conditioning systems and refrigerators. R-12 and R-22 are also detectable by TGS 832. With its good long term stability, TGS 832 is an excellent, low-cost sensor for CFC detection. The figure below represe...
