EH – Level ProbeAccessory

The Caloritech™ EH Level Probe can be used with the SV Electronic Level Control. The assembly consists of a 2″ NPT brass screw plug, weather resistant terminal enclosure and brass sensing rod(s) mechanically held and electrically isolated in porcelain holders

FEATURES

For use with the SV series electronic level controls
Weather resistant terminal enclosure
The rods can be field cut from the 24” (610 mm) supplied lengths to corresponding liquid levels required for control

Level Control (For Conductive Liquids)
The SV series electronic liquid level control senses
the resistance between remote mounted level probe
electrodes (see type EH below). By altering the lengths of
the electrodes, various combinations of high and low limit,
heater ON-OFF and pump ON-OFF can occur as liquid
levels change in the vessel.
When liquid is present, the SV220 de-energizes and the
SV210 energizes. Otherwise both controls are the same.

NOTE:
If the container is non conductive a third (lowest position) electrode must be installed as shown
