EAQ 10/3 IM0015984.PNG Sensor for measuring air quality and air humidity with a linear output signal of 0-10 V. For WS 170 KB.., WR 310/WR 410, WS 320 and WS 470 ventilation units. Depending on VOC and humidity levels, a potential-free switching contact can also be used and its switching point set using a potentiometer. If a potentiometer is completely turned to the right, the respective measurement values are not analysed (VOC and/or humidity). Rated voltage 12 V – 25 V AC or 12 V – 35 V DC

short description

Sensor for measuring air quality and air humidity with a linear output signal of 0-10 V. For WS 170 KB.., WR 310/WR 410, WS 320 and WS 470 ventilation units. Depending on VOC and humidity levels, a potential-free switching contact can also be used and its switching point set using a potentiometer. If a potentiometer is completely turned to the right, the respective measurement values are not analysed (VOC and/or humidity). Rated voltage 12 V – 25 V AC or 12 V – 35 V DC

Product description

  • Sensor for controlling a ventilation unit or fan depending on the air quality.
  • With integrated air quality sensor for measuring the concentration of various gases and odours (e.g. carbon monoxide, methane, hydrogen, alcohol, tobacco smoke).
  • Metal oxide sensor with automatic calibration, takes 2 min. to warm up.
  • With integrated potential-free contact (VOC and humidity).
  • With potential-free relay (n/o contact) with max. 36 VDC / 0.5 A.
  • Setting range of relay: VOC: 800 - 1800 ppm (approx. 1300 ppm when delivered), rel. humidity: 30 - 70 % r.h. (approx. 50 % r.h. when delivered).
  • 0 - 10 volt output.
  • For connecting to WS 170 KBR../ WS 170 KBL.., WR 310/WR 410, WS 320 and WS 470 units.

Safety instructions

  • EAQ 10/3 should not be used in security applications.
