The electro-h ydraulic pressure switch provides an electric
signal when the sensed pressure goes above or below
the selected setting.
Function
The spring loaded piston is hydraulically dampened. The
PSB provides a very accurate hysteresis between the
switching points (see diagram).
The required operating pressure is adjusted by the set-
screw. Unauthorised adjustments can be prevented by
the optional cylinder lock.The electric element is a micro
switch with snap-action contact. Three terminals permit
application as "On", "Off" or "Changeover" switch.
The electrical connection is made with a 3-pole plug-in
connector to EN 175301-803 with ground.
Note
ForinductiveDCloads asparkdischarger should be used
to increase service life.
