The Series CDT, Model CDT-2E44 is a Carbon Dioxide and Temperature Transmitter that precisely measures the CO2 concentration and temperature in interior spaces, helping to save energy. The Series CDT incorporates barometric pressure adjustment to provide even higher precision. To interact with almost any building management controller, customers can choose the transmitter output to be 4-20 mA, 0-5 VDC, or 0-10 VDC using the CO2 universal output. The wall mount variants of the Series CDT can be supplied with an integrated LCD display for applications that need visual indication. An internal dip switch selection can be used to lock out button operation to avoid tampering. The -S option for the Series CDT CO2 transmitters offers the features and characteristics required to meet DSA regulations for CO2 level monitoring in schools. A front-facing LED becomes visible when the CO2 concentration rises above 1100 PPM.
