GfG CC22 CH4 Fixed Transmitter detects methane by means of catalytic combustion. The current measured value can be read at any time on the 2.2-inch display, which lights up red in the event of an alarm. Automatic temperature compensation and linearisation of the measuring signals ensure high measuring accuracy. Signals are transmitted according to the analogue industrial standard (optionally 0.2-1 mA or 4-20 mA) or via the digital RS-485 interface (Modbus protocol). The transmitter indicates operating states via two status LEDs. Service and settings are carried out intuitively on site with a built-in push-button interface (one-man adjustment).
