GfG CC33 CH4 Fixed Transmitter Aluminum is a flame proof gas detector that monitors methane in hazardous areas. The CC 33 is available in a lacquered die-cast aluminum housing with 10mm thick bulletproof glass. It meets the requirements of ignition protection type "d“ for safe use in Ex zone 1. The CC33 transmits measured values and status displays either analogue (4-20 mA) or digitally (RS-485). The currently measured gas concentration is also shown on an LC display. The special stack effect ensures shortest response times of a few seconds for a quick warning of explosion hazards. Three relay outputs provide additional alarm options. In combination with GfG's proven controllers, installation in new gas detection systems as well as retrofitting in existing systems is possible.
