F4/K4
Thrust meters
use as sensitive element a membrane or a piston, depending
on the adjustment range. An electric contact, NO or
NC for the type K4 and SPDT for the type F4, is activated
when the calibration value is reached. An adjustment
screw, mounted on the instrument head, allows setting
the calibration value. Proper mechanic clamps protect
the electric contact from overpressures. The electric
fast-on connections for the type K4 can be protected
by means of a rubber cap IP54.
