GFG CC28 Transmitter

GFG CC28 Transmitter For flammable gases and vapors in Ex zones

If combustible gases and vapors need 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 very short response times of only a few seconds for fast warning of explosion hazards. In combination with GfG's reliable controllers, it can be installed in new gas detection systems or retrofitted into existing ones.

The CC28 uses catalytic combustion (CC) to detect combustible gases and vapours 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 of 0 to 100% LEL and 0 to 4% by volume (NH3). Its automatic temperature compensation and the 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 ingress of dust and water (protection class: IP64). An optional weatherproof housing provides additional protection.

Communication and service
Signals are transmitted via the analog industry standard (4-20 mA). The CC28 uses two status LEDs to indicate its operating status. 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 for function tests can be inserted using a flow adapter.
