CC22 D Transmitter

The CC22 D detects combustible gases and vapors such as methane, propane and hydrogen by means of catalytic combustion (CC). The current measured value is always displayed on the 2.2-inch display, which lights up red in the event of an alarm. The long-life sensors make the CC22 D an economical solution for detecting a wide range of combustible gases in the measuring ranges 0 to 100 % LEL and 0 to 4 % by volume (NH₃). Its automatic temperature compensation and the linearization of the measuring signals ensure high measuring accuracy.

Functional safety and device protection
The hardware of the CC22 D complies with the European Functional Safety Standard DIN EN 61508-2: 2011 (SIL). The housing is protected against the ingress of dust and water (protection class: IP54). An optional weatherproof housing provides additional protection.

Communication and service
The CC22 D uses two status LEDs to indicate its operating status. Signals are transmitted using the analog industrial standard (optionally 0.2-1 mA or 4-20 mA) or the digital RS-485 interface (Modbus protocol). Service and adjustments can be carried out on site, using an intuitive built-in button interface (one-person adjustment). The multi-colored backlit display shows the current measured value, status messages and the CC22 D's menu. Test gases for function tests can be inserted via a calibration adapter.
