Methane Sensor ZMF-201e IR

methane sensor

Robust methane sensor for industrial applications with extended temperature range and extensive approvals.

Product description

The ZMF-201e IR is a methanesensor for measuring methane concentration in harsh environments. The sensor has a robust stainless steel housing and can be used for applications at -40°C. The high-quality and precise methane sensor is certified according to SIL2 and with its measuring range of 0...2,1 vol % it can be used flexibly. ATEX certification is optionally available. For evaluation of the sensor signals, the CH₄ Sensor has a 4...20 mA signal output.
