Conductivity Switch and Controller

■
■

The four different switches of this series can
be used as simple level switches /limiters
or as on/off level controllers. The sensitivity
can be adjusted and the control mode can be
changed over between fill and discharge. For
the electrodes, the tried-and-tested GESTRA
probes are used.

The switches of this series function both in
conjunction with the proven capacitive probes
and also with the level transmitters of the
SPECTORcompact line. The actual-value current
output (available as an option) replaces the level
transmitter. The intuitive, language-neutral,
menu-based operating is performed with the aid
of a rotary pushbutton. The values are indicated
on a 4-digit 7-segment display. The 100% range
setting can be made from a filling level of 25%.

The controllers of this series function both in
conjunction with the usual capacitive probes
and also with the level transmitters of the
SPECTORcompact line. The series now also
offers a modulating control output for pneumatic valves. The intuitive, language-neutral,
menu-based operating is performed with the
aid of a rotary pushbutton. The values are
indicated on a 4-digit 7-segment display. The
100% range setting can already be made from
a filling level of 25%.

The tried-and-tested conductivity switch LRS
1-50 signals excessively high or low conductivity
in the boiler and can be used to actuate a simple
valve. The controllers of this series, LRR 1-5..,
work either in conjunction with a simple conductivity electrode and a separate temperature
sensor or with a conductivity transmitter of the
SPECTORcompact series. Operating and display
is clear and user-friendly, and has been adapted
to the level controllers. All controllers are fitted
with an actual-value output.
