NEW SCH-PSB Differential Pressure Switch for HVAC Applications

NEW SCH-PSB Differential Pressure Switch for HVAC Applications

HVAC APPLICATIONS

The SCH-PSB differential pressure switch monitors overpressure, vacuum, and differential pressure of air or other non-combustible, non-aggressive gases. Typical HVAC applications include: monitoring air filters, monitoring industrial cooling-air ducts, monitoring flow in ventilation ducts, controlling air and fire protection flaps, overheating protection for fan heaters, and frost protection for heat exchangers.

EASY TO OPERATE AND ADJUST

The switching pressure for the SCH-PSB can be adjusted without a pressure gauge using a scaled adjustment knob. The switching differential is easily adjusted with a screwdriver.

SPECIFICATIONS

The SCH-PSB is available in three measuring ranges: 20...300 Pa, 50...500 Pa, and 200...1000 Pa. The maximum pressure is 10 kPa for all ranges. The media and ambient temperature range is -4 to 158 degrees Fahrenheit. The connections are hose barbs.
