Gas Detection Transmitter  BFT-48

Gas Detection Transmitter BFT-48

The industry-proven BFT-48 transmitter accepts Catalytic Bead/IR and electrochemical sensor inputs. These units are available with both two-wire and three-to-four-wire 4-20 mA outputs. The BFT-48 focuses on providing a basic price point solution with no compromise on high performance and safety. 

  • Specs

    • Front LED’s and LCD clearly indicate alarm status. Display
    options for each sensor include engineering units, bar graph and
    30 minute trends.
    • Accepts catalytic bead / IR and electrochemical sensor
    • 10 – 30v DC powered units are configurable as 3 wire single gas or
    4 wire dual gas transmitters with 4 – 20 mA outputs for each
    • “Smart sensor” interface stores sensor type, gas range, alarm set
    points, calibration and other transmitter variables.
    • Non-intrusive magnetic switches allow calibration and local
    interface without area declassification.
    • User programmable “In Cal” output signal, inhibits alarms and notifies receivers during
    calibrations. Programmable “Power Up” and “Post Cal” time delay allows sensor stabilization,
    mitigating false alarms during warm up and calibration completion.
    • A Real time clock and calendar logs all alarm, calibration and power up events.
    • Standard fault supervision circuitry continuously monitors for failures and transmits low mA
    output to signal fault conditions.
    • Security mode allows locking of critical parameters.
    • Available options include alarm relays, RS-485 Modbus®, isolated 4 – 20 mA, Division 2
    quick connectable sets, magnetic mount and pole mounts.
