The methane sensor is an industrial gas sensor used in harsh environments. The overall shell is waterproof and dustproof and has a long service life. The measuring range of this ch4 sensor is 0-100%LEL, and the accuracy is ±5%FS.
Features of methane sensor
The CH4 sensor with explosion-proof ExdIMb explosion-proof grade is stable and durable. Range 0-100%LEL, other ranges can also be customized. The measurement accuracy is high, within ±5% FS, and the repeatability can reach within 2%. Multiple analog signal output options: 4~20mA/0~5V/0~10V/RS485. Optional high-quality OLED display, the value can be viewed directly on site, and can be displayed clearly at night. The on-site power supply adopts 10~30V DC wide-voltage power supply, which can adapt to a variety of on-site DC power supplies. The product adopts wall-mounted waterproof shell, which is easy to install and has a high degree of protection, which can be used in harsh on-site environments.
