Differential Pressure Switch LF32

LF32 is an adjustable 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 adjustment 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.
