The AFF-20... and AFTF-20... are on-wall relative humidity and temperature sensors for universal use in the HVAC applications.
HVAC systems – temperature and humidity measuring in industrial spaces, storage rooms and rooms with increased demands on mechanical sustainability and accuracy of the sensors
The sensor measures temperature and relative humidity of air and other non-aggressive gases. It is used in refrigeration, air conditioning and clean room technology as well as in residential and public buildings. The temperature and humidity sensor signals are converted into active signals 0..10 V. Relative humidity is measured by a capacitive sensor. The sensor is protected by a exchangeable diaphragma filter.
The sensors are intended for operating in a normal and chemically non-aggressive environment. They do not need any servicing or maintenance and can be mounted in any position.
The sensors are fixed to the wall or any flat surface by screws. Holes are reachable after removing the cover.
