FEATURES:
The CD-420 4-20 mA, 2-wire transmitter provides continuous monitoring for toxic and oxygen gas hazards in ambient air. Engineered with BW field-proven industrial sensing and instrument technology, the CD-420 is virtually maintenance free.
A Reduced operating, maintenance and installation costs
A Accurate, reliable performance that eliminates false alarms
A Modular, plug-in encapsulated components and plug-in sensor
A Linear 4-20 mA output with a wide supply voltage range (12 to 35 V)
A Electrochemical sensor
A Micropower analog technology, draws only 20 mA in operation A Hinged operations door A Power ON LED
A If a system fault occurs or the sensor is degrading, the CD-420 will transmit a signal to the controller.
A Change the measuring range or gas sensed in the field (all models except CD-420-3 series carbon monoxide models)
A 2 year, non-prorated instrument and sensor warranty
