Product Description
APPLICATION:
Controlling fire protection flaps in ventilation ducts.Monitoring air filters in cooling and heating systems.
LF32
is an
a
djustable differential pressure switch
capable of detecting miniscule changes in pressure due to the size and proven design. The switch set point or switching point can be field adjustable without the need of a manometer by simply using the adjust ment knob and the built in calibrated visual scale. This switch is equipped a clear cover that not only protects the adjustment knob to be move involuntary but also provides class IP54 protection.
