Part No. CMT-DN-D
Product Overview
The Dwyer CMT-DN-D is part of the Series CMT Carbon Monoxide Transmitters, designed to accurately detect and transmit low concentrations of carbon monoxide in parking garages, loading docks and similar applications. The CMT-DN-D uses a duct-mount configuration and includes a two-line 8-digit alphanumeric LCD display for local indication.
The transmitter provides field-selectable 4-20 mA and 2-10 VDC outputs, allowing connection to most common building management and automation controllers. It measures carbon monoxide from 0-125 ppm with an accuracy of ±2.5% of reading and ±1% repeatability.
The CMT-DN-D typically responds in less than 60 seconds to a 90% step change and can be field calibrated using internal potentiometers. Set points and other configuration settings are password protected. A single transmitter can cover an area of up to 7,500 ft².
The CMT-DN is the corresponding duct-mount configuration without the integral LCD display.
