TGS3830 Description

Short technical summary and product information.

The Figaro TGS3830 is a specialized metal oxide semiconductor gas sensor engineered for the detection of Chlorofluorocarbons (CFCs). Its sensing element, a tin dioxide (SnO2) semiconductor, exhibits a change in conductivity based on the concentration of target gases in the air. This sensor is particularly noted for its high sensitivity and quick response to R-134a, a common alternative refrigerant used in air conditioning systems and refrigerators.

 

The miniaturized sensing element contributes to a low heater power consumption of only 120mW. The TGS3830 is suitable for applications such as portable refrigerant leak detectors, where its performance characteristics make it an excellent, low-cost solution. A simple electrical circuit can translate the sensor's conductivity changes into an output signal proportional to the gas concentration.

 

Typical applications include refrigerant leak detection and portable gas leak detectors. The sensor requires two voltage inputs: heater voltage (VH) and circuit voltage (VC). The heater voltage is typically applied at 0.8V continuously, while the circuit voltage is used in conjunction with a load resistor to measure the sensor resistance.
