Description
The Dwyer CDT Carbon Dioxide & Temperature Transmitter is engineered for accurate indoor air quality monitoring using advanced single-beam dual-wavelength NDIR (Non-Dispersive Infrared) sensing technology. Unlike conventional automatic baseline correction systems, the CDT series directly compensates for sensor aging and environmental changes, ensuring stable and reliable CO₂ readings even in continuously occupied spaces such as hospitals, schools, and manufacturing facilities. The transmitter supports both CO₂ and temperature measurement in a single compact device, reducing installation cost and simplifying wiring. Universal outputs including 4–20 mA, 0–5 VDC, and 0–10 VDC make integration with building management systems (BMS), HVAC controllers, and PLCs straightforward.
In addition, the CDT Series includes optional LCD display configurations for real-time local indication of COâ‚‚ concentration and temperature values. The device offers user-friendly push-button configuration, field calibration capability, adjustable barometric pressure compensation, and optional relay outputs for ventilation control or alarm activation. Its rugged housing design supports wall-mount and duct-mount installations, making it suitable for a wide range of indoor air quality applications. With low power consumption, long sensor life up to 15 years, and high measurement accuracy, the CDT Series provides a dependable solution for modern energy-efficient ventilation systems.
