Switches F/K3 Membrane/Piston
F3/K3 Pressure switches use as sensitive element a membrane or a piston, depending on the adjustment range, allowing the activation of a microswitch, when the calibration value is reached. An adjustment screw, mounted on the instrument head, allows setting the calibration value. Proper mechanic clamps protect the microswitch from overpressures. The electric faston connections for the type F3/F3S can be protected by means of a rubber cap IP54.
Use / Characteristics
 
- Pressure ranges from 0,05 to 250 bar.
- Easy to use and to adjust.
- Easy assembling.
- High power electric contact.
 
These instruments are mainly used as pressure controls of industrial plant engineering, in oilhydraulics and pneumatics, on pumps, manufacturing machines, etc.
