Cat No: CCGS-LJX-0008 Datasheet
Product Name: Catalytic Combustion Combustible Gas Sensor, 1% methane: MC112: 20～40
Quantities: - +
| Detailed Description | The catalytic element works based on the principle of catalytic combustion effect. It consists of two arms of a bridge composed of a detection element and a compensation element. When a flammable gas is encountered, the resistance of the detection element increases, and the output voltage of the bridge changes. This voltage change increases proportionally with the increase of gas concentration. The compensation element serves as a reference and provides temperature and humidity compensation. |
| Main Applications | Concentration detection of flammable gases such as natural gas, liquefied petroleum gas, coal gas, and alkanes in industrial sites; flammable gas leak alarms; flammable gas detectors; gas concentration meters. |
