Dwyer Instruments Series CDTA carbon dioxide transmitters

Monday, 30 June, 2014 | Supplied by: Dwyer Omega (Aust) Pty Ltd


The Series CDTA are combination sensors which measure carbon dioxide, humidity and temperature and transmit the measurements to the building controller. The devices, which also feature occupancy override and temperature setpoint measurements, allow for the transmitters to be daisy chained with other communicating sensors.

Carbon dioxide measurements are taken using a single-beam, dual-wavelength, non-dispersive, infrared (NDIR) sensor. Humidity measurements are measured using a capacitive polymer sensor and the temperature is recorded by a solid-state band gap sensor.
