Product Description
Ordering Key
SV 150 024
Level control relays for
capacitive sensors, types VR
and VRY. The relays can con-
trol one or two levels of
charging (SV 160/260) or discharging (SV 150/250).

Mode of Operation
Max. and/or min. control of
solid, fluid or granulated
substances, e.g. sand,
gravel, sugar or chemicals.
SV 150/250: Relay control of
DISCHARGING
SV 160/260: Relay control of
CHARGING
Example 1
The diagram shows the level
control connected as max.
and min. control, i.e. registration of 2 levels during charging (discharging).
The relay releases (operates)
when the max. sensor is in
contact with the substance,
provided that the min. sensor
is immersed. The relay operates (releases) when the min.
sensor is no longer in contact
with the substance.
Example 1
The diagram shows the level
control connected as max. or
min. control, i.e. registration
of 1 level during charging (discharging).
The relay releases (operates)
when the sensor is in contact
with the substance.
