Product Details

 

                                                  LF32 Sensitive (differential) Pressure Switch for Air

The LF32 is an adjustable differential pressure switch capable of detecting miniscule 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 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, flaps are critical.

Some specific applications of the LF32 adjustable differential pressure switch are :

Controlling fire protection flaps in ventilation ducts

Monitoring 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 heat exchanger

The LF32 Adjustable differential pressure switch can also be used as an adjustable pressure switch and adjustable vacuum switch as well.
