Power Requirements16 to 35 VDC / 19 to 28 VAC
RangeCO2 0 to 2000 or 0 to 5000 ppm
Relative Humidity 0 to 100%
Temperature32 to 122F (0 to 50C)
Non Linearity16 ppm
Series CDTR Carbon Dioxide, Relative Humidity and Temperature Transmitters reduce the number of sensors mounted on a wall or in a duct. By combining RH, CO2 and temperature in one device, system integrators are able to lower installation time of mounting multiple housings, while lowering material cost at the same time.

  • Range:CO2: 0 to 2000 or 0 to 5000 ppm (depending on model); Relative Humidity: 0 to 100% ; Temperature: 32 to 122°F (0 to 50°C).
  • Accuracy:±40 ppm 3% of reading (CO2); ±2% (RH).
  • Temperature Dependence:±8 ppm/ °C at 1100 ppm.
  • Non-Linearity:16 ppm.
  • Pressure Dependence:0.13% of reading per mm of Hg.
  • Response Time:2 minutes for 99% step change.
  • Temperature Limits:32 to 122°F (0 to 50°C).
  • Humidity Limits:10 to 95% RH (non-condensing).
  • Power Requirements:16 to 35 VDC / 19 to 28 VAC.
  • Power Consumption:Average: 2 watts; Peak: 3.75 watts.
  • Sensor:Single-beam, dual-wavelength NDIR.
  • Output:Current: 4 to 20 mA (max 500 O); Voltage: 0 to 5 VDC or 0 to 10 VDC (min 500 ?); Relay: SPST NO 2A @ 30 VDC; RTD or thermistor per r-t curves (depending on model).
