SERIES CDT CARBON DIOXIDE/TEMPERATURE TRANSMITTER

NDIR CO2 Sensor, Universal Outputs, Optional Relay

The Series CDT Carbon Dioxide and Temperature Transmitters accurately monitorthe CO2 concentration and temperature in indoor environments to help achieve energysavings. In order to achieve a higher level of accuracy, the Series CDT includesbarometric pressure adjustment. The CO 2 universal output allows users to select thetransmitter output to be 4-20 mA, 0-5 VDC, or 0-10 VDC to work with virtually anybuilding management controller.
For applications that require visual indication, the wall mount configurations of theSeries CDT can be ordered with an integral LCD display. To prevent tampering, theaction of the buttons can be locked out using an internal dip switch selection.

*For buildings occupied 24 hours per day, it is recommended that calibration be verified every 6 to 12 months depending on application.
