Description
Room CO2 and temperature sensor or measuring transducer
AERASGARD® FSCO2/FSTM-CO2
The AERASGARD® FSCO2 / FSTM - CO2 room climate transmitter with in-wall housing is used for measuring The CO2 content and temperature of the air. It converts the measured values into a standard signal of 0-10 V.
The CO2 content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). A digital, long-term stable sensor is used for temperature measurement.
The in-wall measuring transducer is mounted either individually or in combination with light switches, socket outlets, etc. in high-quality panel switch brand programmes, such as preferably from Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (with in-wall adapters).
