CDTD19 / Duct CO2 Trans, 0-2000ppm with 10K-III NTC Thermistor, 0-10Vdc/4-20mA, IP65, 15 year life

CDTD Carbon Dioxide (CO2) / Temperature Transmitter

The CDTD CO2 Transmitter provides a reliable way to monitor duct air in HVAC systems. It measures both carbon dioxide and temperature with high accuracy. This professional tool helps you manage the air quality in large buildings and industrial spaces. By tracking gas levels, it ensures your ventilation runs efficiently. It helps you keep indoor air fresh while reducing total energy costs. You can explore more duct-mounted sensors in our catalog here.

High Accuracy with the CDTD CO2 Transmitter

This model uses a professional NDIR sensor to track carbon dioxide levels. It includes a built-in ABC algorithm to manage the sensor calibration. This smart technology allows the device to calibrate itself automatically over time. It reduces the need for manual maintenance and site visits. The CDTD CO2 Transmitter offers a measurement range from 400 to 2000 ppm. This precision helps your facility meet standard indoor air quality guidelines.

Easy Integration for the CDTD CO2 Transmitter

The CDTD series fits easily into any modern building automation system. It offers many output options to match your controller’s needs. You can choose from 4-20mA, 0-10V, or RS485 Modbus signals. These flexible outputs allow the sensor to work with almost any HVAC system. The diffusion sampling method ensures the sensor gets a clean air sample from the duct. This leads to faster response times and more reliable data for your building.

Advanced Temperature and Climate Sensing

Beyond gas monitoring, this device tracks the temperature of the air stream. It uses a digital sensor or a thermistor to provide accurate thermal data. The temperature range covers 0°C to 50°C, which is perfect for most HVAC ducts. This dual-sensing feature saves you money by reducing the number of sensors needed. It provides all the data required to optimize your heating and cooling cycles.
