Differential Pressure Monitor 100 To 1000 Pa - Color: White

GEMTECH Differential Pressure Monitor 100...1000 Pa

GEMTECH Differential Pressure Monitor 930.8x With Adjustable Switching Pressure

Applications

GEMTECH adjustable differential pressure monitors are used for monitoring overpressure, vacuum, and differential pressure of air or other nona combustible, nona aggressive gases. Possible fields of application include:

Monitoring air filters and ventilators

Monitoring industrial coolinga air circuits

Overheating protection for fan heaters

Monitoring flows in ventilation ducts

Controlling air firea protection flaps

Frost protection for heat exchangers

Versions

With this pressure monitor, the switching pressure can be adjusted without a pressure gauge using a scaled adjustment knob. The switching differential can also be adjusted with a screwdriver.
