描述

Siemens Symaro™ Room sensors QFA31..for relative humidity (high accuracy) and temperature

  • 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
  • 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
  • With the AQF3100 accessory for outdoor use
