2-Wire Gas Transmitter
B12 2-Wire Gas Transmitter
Loop-powered monitoring of hazardous gases in ambient air
The B12 from Badger Meter (GasSens / ATi) is a loop-powered 2-wire transmitter that sends a 4-20 mA signal proportional to gas concentration, for a wide range of toxic gases and oxygen.
Manufactured byBadger Meter
Overview
About B12 2-Wire Gas Transmitter
Operated from 24 V DC, the B12 drives loads up to 675 Ω; it can also run at 12 V DC with reduced load for battery-powered applications. Sensors are normally coupled to the enclosure but can be mounted up to 25 ft away.
Duct-mounting adapters and sensor flow cells are available. For display and alarms, the transmitter connects to B14 alarm receivers or directly to a PLC or DCS.
