The LF32-03 is an adjustable differential pressure switch capable of detecting minuscule changes in pressure do to its size and proven design. The switch set point or switching point can be field adjustable with out the need of a manometer by simply using the adjustment knob and the built in calibrated visual scale. This switch is equip with a clear cover that not only protects the adjustment knob to be move involuntary but also provides class IP54 protection.
The LF32-03 adjustable pressure switch is primarily used in heating and ventilation application where the need of accurately monitoring air flow in air duct systems, air filters, dampers are critical.
Some specific applications of the LF32-03 adjustable differential pressure switch are :
Controlling fire protection flaps in ventilation ductsMonitoring air filters in cooling and heating systems
Monitoring cooling systems of industrial electronic circuits,
Monitoring positive pressure on pressurized rooms
Monitoring air flow on fan heaters (over heating protection)
Frost protection for air heat ex-changer
The adjustable differential pressure switch can also be used as an adjustable pressure switch and adjustable vacuum switch as well.
