TGS3830

Gas sensor with high sensitivity to R-134a, the most promising alternative to R-12, commonly used in air conditioning systems and refrigerators.

The quick response speedand the low-cost make the sensor ideal for portable refrigerant leak detector.

In the presence of the gas to detect, sensor conductivity increases according to 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.

Due to the miniaturized sensing chip, the heater requires a current of only 120mW.
