AERASGARD FSFTM - CO2 - Modbus
The room sensor and measuring transducer AERASGARD
measure the CO2 content, relative humidity and temperature of the air, and for setpoint adjustment. The measured values are queried via the
Modbus interface. 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 humidity and temperature measurement. Relative humidity [% r. H.] is the quotient of water vapour partial pressure divided
by the saturation vapour pressure at the respective gas temperature. The in-wall sensor is mounted in high-quality panel switch programmes,
ideally of the brands Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using in-wall adapters, no setpoint adjustment possible) either individually
or in combination with light switches, socket outlets, etc. It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and
clean room technology, and in interior rooms, such as living rooms, offices, hotels, etc.
