Transmitter measuring combustible gases and vapors by the catalytic combustion principle, ATEX certified for Ex zone 1.
Description
About CC28
CC28 is a GfG fixed transmitter that uses the catalytic combustion principle to measure the concentration of combustible gases and vapors such as methane, propane and hydrogen in the 0 to 100% LEL range. The unit carries ATEX II 2G Ex demb [ib] IIC T4 Gb certification and is suitable for installation in Ex zone 1 hazardous areas. The analog 4-20 mA output connects to GfG central gas controllers. Three versions are available: CC28 (basic), CC28 D (with display) and CC28 DA (with display plus horn and LED alarm).
