1. General
E
The following instructions must be followed in full
to ensure correct use of this fluid level sensor.
2. Function
HYDAC fluid level sensors monitor the fluid level
in a hydraulic tank.
The switching signals (max. switching current 0.2 A)
can be used as a warning message to regulate
the fluid level or directly in a PLC control.
On the dual switching circuit, both opening and
closing functions can be used for control
or evaluation.
FSK-2SP
When the maximum or minimum level is reached,
this state is transmitted via electrical switching
signals.
FSKV
When the adjustable maximum or minimum level
is reached, this state is transmitted via electrical
switching signals.
In addition, variable advance warning points
can be pre-set.
Visual indication of the fluid level is also guaranteed.
