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.
