Ceramic base gas sensor resistant to severe environments for leak detection from refrigerators
The sensing element of TGS826 is a metal oxide 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 TGS826 has high sensitivity to ammonia gas. The sensor can detect concentrations as low as 30ppm in the air and is ideally suited to critical safety-related applications such as the detection of ammonia le aks in refrigeration systems and ammonia detection in the agricultural field.
Features:* High sensitivity to ammonia * Quick response to low concentrations of ammonia * Uses simple electrical circuit * Ceramic base resistant to severe environment
Applications: * Ammonia leak detection in refrigerators * Ventilation control for the agricultural and poultry industries
