ATIs B12 2-Wire Modular Gas Detector is a flexible component system providing a variety of options to meet individual gas detection and alarm requirements. Series B12 transmitters are loop-powered instruments that transmit a 4–20 mA signal linearly proportional to gas concentration.
The B12 detection systems consist of individual modules that can be located where required. Sensor/transmitters, located in the area where gas leakage or buildup might occur, provide the basic measurement for the system. Sensor transmitters are available in either NEMA 4X or explosion-proof versions.
Transmitters are normally supplied with the sensor close coupled to the enclosure. However, for special applications, the unit can be supplied with separate sensors that can be located up to 25 feet from the transmitter. Sensor duct mounting adapters and sensor flowcells can also be provided for specific applications.
