Product Overview
The Dwyer CMT200 is a carbon monoxide transmitter designed for monitoring CO concentrations in underground parking garages, vehicle maintenance facilities, mechanical rooms and other applications requiring continuous carbon monoxide detection.
The transmitter measures carbon monoxide from 0 to 200 ppm and provides a field-selectable output of either 4-20 mA or 2-10 V. The output is selected using an internal jumper, allowing the transmitter to interface with a wide range of building automation and control systems.
The CMT200 uses a field-replaceable electrochemical sensor with a typical lifespan of 4 years and provides a typical coverage area of 5,000 to 7,000 ft², depending on the application and installation conditions.
Field calibration is performed using the 15-turn zero and span potentiometers together with the A-507A calibration adapter and GCK-200CO-2000CO2 calibration gas when required. The housing is made from UV-resistant polycarbonate and includes removable terminal blocks with PG11 and PG16 conduit knockouts.
The CMT200 is the standard version. The CMT200-FC version has the same core specification and additionally includes a factory calibration certificate.
