The basic B12 Wet Gas Detector system consists of a loop-powered 2-wire transmitter and a corrosion resistant sensor specifically engineered to operate at 100% RH. Gas sensors are designed for direct insertion into vent stacks, or may be used in a flow-cell if a sample can be pumped to the sensor. When remote display and alarm relay functions are required, the B12 wet gas transmitters can be connected to ATI’s B14 Gas Alarm Module. This receiver system will provide direct digital display of gas concentrations, plus 3 alarm set points, a remote alarm reset input, and retransmitted 4-20 mA output. The B12 wet gas transmitter may also be used separately and tied directly to the user’s DCS, PLC, or other equipment. Either way, the B12 Wet Gas Detector is an excellent solution to a difficult gas monitoring problem.
