CDT Duct CO2 transmitter for duct - 1

USER-FRIENDLY MEASURING DEVICES carbon dioxide transmitters CDT2000 duct series Multifunctional, duct mount CO2 transmitters for building automation systems The CDT2000 Duct series air quality transmitters are engineered for building automation systems in the HVAC/R industry. The CDT2000 Duct series measures carbon dioxide (CO2), utilizing the industry standard NDIR measurement principle, and temperature (T). Illuminated display ensures easy readability also from a distance. The CDT2000 Duct has a screwless lid and an easily adjustable mounting flange that make the installation of the device easy. The CDT2000 Duct series transmitters calibrate themselves automatically using ABC™ logic. The ABC™ logic requires that the space in which the transmitter is used needs to to be unoccupied for four hours per day so that the indoor C02 concentration drops to the outside level. CDT2000-DC Duct is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDT2000-DC Duct is also suitable for buildings that are continuously occupied. CDT2000 Duct series devices include: • Separate field configurable output for each measurement parameter (C02, T) • Mounting flange CDT2000 Duct series device options offer: • Clear backlit display • Modbus configuration CDT2000 Duct series devices are commonly used to monitor: • CO2 levels of incoming and return air in ventilation system • CDT2000-DC Duct series devices can also be used in applications where there is a constant source of carbon dioxide present (for example hospitals and greenhouses) Copyright HK Instruments 2017 www.hkinstruments.fi Datasheet Version 6.0 2017
