Serie CDT

Product catalog summary

Specifications:
The brochure outlines the specifications for Dwyer Instruments' CO2 transmitters. The CO2 range is either 0 to 2000 ppm or 0 to 5000 ppm, depending on the model. Temperature range is 32 to 122°F (0 to 50°C), and humidity is 0 to 100% RH for CDTR and CDTA models. Accuracy is ±40 ppm + 3% of reading for CO2 and ±2% RH. The devices operate within 32 to 122°F and 10 to 95% RH (non-condensing). Power requirements are 16 to 35 VDC or 19 to 28 VAC, with an average power consumption of 2 watts.

Sensor Technology:
The transmitters use a single-beam, dual-wavelength NDIR sensor to reduce errors from light source aging. This technology provides higher accuracy compared to Automatic Baseline Correction methods.

Features:
The devices offer field-selectable current/voltage output, optional relay output for immediate notifications, and a remote display connector for easy monitoring. The Series CDT and CDTR models include options for different configurations and outputs, such as 4 to 20 mA or 0 to 10 VDC.

Applications:
These transmitters are designed for use in schools, office buildings, and other indoor environments to help achieve LEED® certification. They are suitable for environments like hospitals and manufacturing plants that are occupied 24 hours a day.

Installation and Configuration:
The devices feature removable terminal blocks to reduce installation time and push buttons for menu navigation and calibration. The CDTA model supports Modbus® and BACnet communications, allowing for daisy-chaining to reduce installation costs.

Advantages:
The single-beam dual-wavelength sensor automatically corrects for aging effects, ensuring accurate readings in both occupied and unoccupied buildings. The design reduces energy costs through on-demand ventilation and minimizes installation and replacement costs by combining multiple sensors into one unit.

Reduce Energy Cost Using On Demand Ventilation Series CDT Series CDTA Right Choice. Right Price. Right Now. Series CDT Carbon Dioxide and Temperature Transmitters accurately monitor the CO2 concentration and temperature in schools, office buildings, and otheMndoor environments to help achieve LEED certification. For increased sensor accuracy, a single-beam dualwavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied and unoccupied buildings against light source aging effects. The single-beam dual-wavelength sensor technology provides the...
