- Room sensors QFA31…for relative humidity (high accuracy) and temperature
- Signal output DC 0...10 V / 4…20 mA for relative humidity and temperature Operating voltage AC 24 V / DC 13.5...35 V
- Very high measuring accuracy across the entire measuring range
- Capacitive humidity measurement
- Function test
- Range of use −40…+70 °C / 0…100 % r. h. with LCD display −25…+70 °C / 0…100 % r. h.
The QFA31… is for use in ventilation and air conditioning plants where high accuracy and short response times for measuring relative humidity are required. The measuring range covers the entire humidity range of 0…100 %.
Examples:
Storage and production facilities in the paper, textile, pharmaceutical, food, chemical and electronics industry, etc.
Laboratories
Hospitals
Indoor swimming-pools
Computer and EDP centers
Greenhouses
