For flammable gases and vapors in Ex zones
If combustible gases and vapors are to be monitored in Ex zones, the CC28 transmitter is a reliable and economical solution. The CC28 uses an analog (4-20 mA) signal to provide measured values and status information. The special stack effect ensures shortest response times of a few seconds for a fast warning of explosion hazards. In combination with GfG's proven controllers, installation in new gas detection systems as well as retrofitting in existing systems is possible.
The CC28 uses catalytic combustion (CC) to detect combustible gases and vapors such as methane, propane and hydrogen. The long-life sensors make the CC28 an economical solution for detecting a wide range of combustible gases in the measurement ranges 0 to 100% LEL and 0 to 4% by volume (NH3). Automatic temperature compensation and linearization of the measurement signals ensure high measurement accuracy.
Explosion protection, functional safety and device protection
The CC28 has ATEX certification for use in Ex Zone 1, and its hardware complies with the European Functional Safety Standard DIN EN 61508-2: 2011 (SIL). The housing is protected against dust and water ingress (protection class: IP64). An optional weatherproof housing provides additional protection.
Communication and service
Signal transmission is done via the analog industry standard (4-20 mA). Operating states are indicated by the transmitter via two status LEDs. Service and adjustments are carried out on site using the optional RC2 remote control (one-man adjustment). The pre-adjusted sensors can be easily replaced thanks to Smart Sensor technology. Test gases can be supplied for function tests using a flow adapter.
