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.
