Carbon Dioxide (CO2) transmitter CDD with
Duct Mounting Set DMS 300G for duct mounting
Duct Mounting Set DMS 300G
Description
Carbon Dioxide (CO2) transmitters CDD-series with two-beam infrared sensor for the continuous monitoring of the ambient air to detect carbon dioxide concentrations.
The infrared measuring method with integrated temperature and drift compensation stands for highest accuracy, selectivity and reliability despite of the calibration interval of 5 years.
The Carbon Dioxide (CO2) transmitters CDD-series possesses a standard analog output (0)2-10 Vdc or (0)4-20 mA, and an RS-485 interface. 2 relays with adjustable switching thresholds as well as an integrated display are available as options.
Application
Carbon Dioxide (CO2) transmitter CDD-series for detecting leakages in refrigeration plants with carbon dioxide as refrigerant, and also within a wide range of commercial and industrial applications.
The measuring ranges 0-2000 ppm and 0-5% vol. is provided for the indoor air quality control.
Due to the standard analog signal (0)2-10 Vdc or (0)4-20 mA and the RS-485 serial interface the Carbon Dioxide CO2 transmitter CDD-series is compatible to controllers or automation systems.
