Product Description
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 dis-
charging (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. registra-
tion of 2 levels during charg-
ing (discharging).
The relay releases (operates)
when the max. sensor is in
contact with the substance,
provided that the min. sensor
is immersed. The relay oper-
ates (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 (dis-
charging).
The relay releases (operates)
when the sensor is in contact
with the substance.
