K52 piston type differential pressure switches allow a micro-switch actuation upon the reaching of a differential value between two pressures.
They are available in two versions:
K52F – Fixed set point, Actuation occurs when the maximum pressure P2 exceeds the minimum pressure P1 by an average of 20%.
K52R – Adjustable set point, the preset pressure is found by rotating the regulating screw located at the top of the instrument.

Rotate the screw clockwise to increase and counter-clockwise to decrease the value.

Mechanical stops protect inside components from over pressurization and inversion of the pressures values.

Technical Features:
Anodized aluminum body which can be connected to the system with a 1/4"BSPF for the type K52F, 1/4"BSPF and 1/8"BSPF for the type K52R.
Installation position: it can be mounted in any position.
Working temperature: from -20°C to +80°C
Switching frequency: 60 cycles/min.
Switching accuracy: w 5% of set pressure
Fixed hysteresis value: about 20% of the maximum working pressure value
Weight: 0.47 Kg.
