SDC-C1 - Duct mount

Smart CO2 transmitter duct mount

The CO2 concentration is measured through non-dispersive infrared (NDIR) waveguide technology with ABC automatic background calibration algorithm. The applied measuring technology guarantees excellent reliability and long term stability. The microprocessor samples the CO2 once per second. It calculates an averaging signal over a preset number of seconds and generates the output signal. Ranges can also be set by using the optional internal or external display and programming module OPC-S or OPA-S.

Applications

Demand based ventilation for homes and offices based on measurement of the CO2 concentration. Preset standard measuring range 0...2000 ppm, max. possible range 0...5000 ppm
Recording of minimum and maximum limits for critical environments
Direct control of extraction fan
