AERASGARD
FSFTM - CO
The room sensor and measuring transducer AERASGARD
measure the CO
content, relative humidity and temperature of the air, and for setpoint adjustment. The measured values are queried via the
2
Modbus interface.
The CO
content of the air is measured using an optical NDIR sensor (non-dispersive infra-red technology). A digital, long-term stable sensor is used
2
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.
