TGS3830 for the detection Chlorofluorocarbons
Features:
* Low power consumption
* High sensitivity to R-134a
* Quick response to R-134a
Applications:
* Portable refrigerant leak detector
TGS 3830 is Figaro's new metal oxide semiconductor gas sensor for the detection of Chlorofluorocarbons. The sensing element of the sensor is a tin dioxide (SnO2) semiconductor which has low 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. Miniaturization of the gas sensing bead results in a heater power consumption of only 120mW.
The TGS3830 has high sensitivity to R-134a, the most promising alternative to R-12, commonly used in air conditioning systems and refrigerators. With its quick response speed, TGS3830 is an excellent, low-cost sensor for portable refrigerant leak detector.
