Dwyer CDT Series Carbon Dioxide and Temperature Transmitters measure the concentration and temperature of CO2 in schools, office buildings and other indoor environments to help achieve LEED ® certification. For improved sensor longevity, a single-beam dual-wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct aging effects in both occupied and unoccupied buildings.

Applications: Demand control ventilation in schools, office buildings, hospitals, and other indoor environments

Product Description

Dwyer CDT Series Carbon Dioxide and Temperature Transmitters measure the absorption of CO2 and temperature indoor areas to ensure energy savings. For greater sensor precision, a single beam dual-wavelength nondispersive infrared (NDIR) system is mostly used to automatically correct the measurement towards light source aging effects both in occupied * and unoccupied building structures. Similar to Automatic Baseline Correction methods, the single-beam dual-wavelength sensor technology offers the highest degree of precision and can accidentally change the calibration based on CO2 levels and barometric pressure.

Features of Dwyer CDT-5D40 Carbon Dioxide Transmitter :

  • Single beam dual-wavelength NDIR sensor eliminates draft due to light source aging
  • Optional integral display and relay output
  • Integral passive temperature outputs reduce the number of devices mounted in the space
  • Service display tool available for models without an integral LED
