Level switches are used to monitor the level of fluids in unpres
surized reservoirs. Various versions are available to meet the
different requirements related to the monitoring of fluid levels.
– Switches with one switching point (WS32 …), e.g. ones used
to monitor the minimum level of fluid in a reservoir.
– Switches with two switching points (WS35 …), likewise used
to monitor the minimum level of fluid, an advance warning
being emitted before a critical level is reached and without
having to shut down the machine. Before the second switch
ing point is reached, there is still eugh oil in the reservoir for
a shift to be completed without having to s the machine or
interrupt work.
– Switches with two switching points (WS33 …), e.g. for a mini
mum and maximum level of fluid in the reservoir, automatic
ping up of the reservoir being terminated, for example,
before the maximum level is reached.
Further level switches, e.g. for other fluids like NLGI grades 000
and 00 grease, are available on request (capacitive proximity
switches).
