Product Introduction
1. Description of Combustible Gas Sensor TGS816:
The sensing element of Figaro sensors is composed of a tin dioxide (SnO2) semiconductor, which has low conductivity in clean air. When the target gas is present in the air, the higher the gas concentration, the higher the sensor's conductivity. Using a simple circuit, the change in conductivity can be converted into a signal output corresponding to the gas concentration.
Combustible Gas SensorsTGS816It not only detects a wide range of combustible gases but also features a ceramic base that can withstand high temperatures up to 200°C. It has high sensitivity to methane, propane, and butane, making it the ideal sensor for monitoring LNG and LPG. Due to its sensitivity to multiple gases, it can be widely used in various fields, making it an excellent cost-effective sensor.
