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.
When remote display and alarm relay functions are required, the B12 Wet Gas Transmitters can be connected to ATI's B14 Alarm Receiver System. This system will provide direct digital display of gas concentration, plus 3 alarm setpoints, remote alarm reset input, and retransmitted 4-20 mA output. Or, the B12 transmitter may be used separately and tied directly to the users' DCS, PLC, or other equipment.
Universal power supply modules provide DC power to receivers. The power supply is housed in a compact module similar to the receiver, and will accept inputs from 85 to 265 volts, AC or DC, without adjustment. The power supply also provides a power failure relay and charging for an optional battery back-up unit.
