CDTR-2D404

CDTR-2D404 is a series CDTR carbon dioxide, relative humidity and temperature transmitters reduce the number of sensors mounted on a wall or in a duct. By combining CO2, RH, and temperature in one device, system integrators are able to reduce installation time while lowering material cost at the same time. Like our popular Series CDT Carbon Dioxide Transmitter, a non-dispersive infrared (NDIR) sensor is used to make the CO2 measurement. In order to achieve the best possible accuracy, the series CDTR also includes digital barometric pressure adjustment. Universal outputs for both carbon dioxide and relative humidity allow users to select the transmitter output to be 4-20mA, 0-5VDC, or 0-10VDC to work with virtually any building management controller. Additionally, passive thermistor or RTD sensor can be ordered for a temperature output.

• Range 0 to 2000PPM CO2 range
• Duct mount
• 4-20mA / 0 to (5 or 10) VDC CO2 and RH output
• Minimize inventory and save time by combining CO2, RH, temperature measurements into one transmitter
• Reduces the number of devices mounted in the space with integral humidity and temperature sensors
• Requires minimal maintenance with Automatic Baseline Correction (ABC) to account for sensor drift
• Field selectable Modbus® and BACnet communications reduces wiring
• Simplify installation with backplate electrical connection
• Temperature limits: 32 to 122°F (0 to 50°C), humidity limits: 0 to 85% (non-condensing)
