Specifications︰Operating voltage AC 24 V / DC 13.5...35 V
• Signal output DC 0...10 V / 4…20 mA for relative humidity and temperature
• Very high measuring accuracy across the entire measuring range
• Function test
• Capacitive humidity measurement
• Range of use −40…+70 °C / 0…100 % r. h.
with LCD display −25…+70 °C / 0…100 % r. F.
Use
The QFM31… 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 %.
• Storage and production facilities in the paper, textile, pharmaceutical, food, chemical
and electronics industry, etc.
• Laboratories
• Hospitals
• Computer and EDP centers
• Indoor swimming pools
• Greenhouses
The QFM31… is used as a
• control sensors in the supply or extract air
• limit sensor for maximum limitation of supply air humidity after a steam humidifier
• limit sensor, e.g. for measured value indication or for connection to a building
automation and control system
• sensor for enthalpy and absolute humidity, together with the AQF61.1 (refer to Data
Sheet N1899) or SEZ220 (refer to Data Sheet N5146)
