On - Off Level Control
The 701 is used with a
Hydrostatic piezo resistive Level
transmitter and cable bracket
or as a separate unit.
For control of 1 pump and 1
alarm or for 2 pumps in
The 704 is used with either an
Ultrasonic sensors or a
Hydrostatic piezo resistive
Level transmitter. Used to
control up to 4 pumps or valves
between adjustable levels.
501 Electrode Level Control + Relay
The 501 level relay with electrodes are most commonly used as a simple
safety device providing level alarms in case of water leaking on floors with
no constant monitoring. The 501 provides an alarm signal based on the
conductivity in the liquid thereby securing the important electronics or
non-submersible pumps. Some waste water plant also uses 501 as an
additional security device providing alarm signals or starting pumps
based on the 2-4 electrodes in individually adapted lengths.
7030 Float Switch
The 7030 Float switch is most
commonly used in waste water
pumping stations and sewage
treatment plants. In case of
heavy sludge layer the float
switch will work submerged
with the counterweight.
