AirFlow sensor 5101

SL5101 calorimetric sensor detects air flow below or above a specified threshold in 1 to 10 m/s range and its output is a normally-open relay contact. The sensor needs a 24VDC power supply.

Features: 
  • Sensor switches relay, when air-flow step up over setting level
  • Input voltage 24V DC, 1VA
  • Body lenght 140 mm, 23mm diameter
Applications and usage: 
  • Ventilation run detection
  • HVAC system monitoring
  • Wind detection
