WPS COMMERCIAL DIFFERENTIAL PRESSURE SWITCH

WPS COMMERCIAL DIFFERENTIAL PRESSURE SWITCH
Conforms to CERoHS Compliant

APPLICATIONS:

  • Field applications include: monitoring air filters and ventilators, overheating protection for fan heaters and controlling air and fire protection flaps, protection for heat exchangers, flow in ventilation ducts and controlling

DESCRIPTION & FEATURES:

  • Excellent solution in BAS and HVAC applications requiring monitoring and control
  • Low pressure differential switch for monitoring pressure, vacuum and differential pressure of air and other non combustible, non aggressive gases
  • Pressure indicating adjustment knob allows for simple field changes without the need of a pressure gauge
  • Pressure ranges in both Inches of Water (and Pascals), from 0.08 to 16.0 (20-4,000)
  • Single-pole double-throw (SPDT) switch type with 0.01A 250 VAC output
  • The compact size allows for hassle-free installation in small areas
  • CE, RoHS & REACH compliant
  • 5 year warranty
