• Rugged, durable, polyurethane encapsulated transmitter with sensor
• Quick disconnect with military-style plug-in wiring connector during installation and decommissioning
• 2 year operational life
• Daily, automatic, full-function self-test of sensor and circuitry integrity
• LED red visual alarm
• Electrochemical sensor for H2S and catalytic bead sensor (combustible gases)
• Wide supply voltage range,10 to 28 VDC for industry standard compatibility
• Low initial cost, competitively priced

RRJ Transmitters with Sensor

BW Technologies introduces the first zero-maintenance, 4-20 mA transmitters on the market. BW Technologies has applied cuttingedge science developed for the world's most advanced disposable gas detector, the GasAlertClip to the RRJ Series of transmitters.

Daily Automatic Self-Test

Daily Automatic Self-Test The full function self-test is a unique safety advantage. The sensor integrity is tested as well as the circuitry integrity. The full function sensor integrity test not only advises if the sensor is present, but additionally tests the sensor's response and advises if the sensor is defective.

Operational Life

The operational life is two years in normal use. The life counter is activated when power is applied and runs continuously while the transmitter is operating. If power is interrupted, the counter stops and will resume counting when power is restored.

Life-Ended Warning and Alarm

One month prior to the end of the transmitter's operational life, the LED will begin a slow fl ash warning. When the 2 year operational life is over, the monitor will send a 2 mA signal to the controller advising that the monitor is now disabled and requires replacement.
