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.
