LS7000/2 LEVEL SWITCH

1. DESCRIPTION

A. General Description

The LS7000/2 dual point level switch is designed to automatically maintain a level between two points along a

vertically mounted probe. The two setpoints are adjustable over the entire length of the probe.

The LS7000/2 can be used to automatically fill a tank, or automatically pump down a sump.

A single relay, DPDT, 5 amp, is used for control. An on board latching circuit prevents the relay from changing

state until the high or low setpoints are reached.

The basic unit is made up of a solid stainless steel probe attached to an explosion proof housing. Inside the

explosion proof housing are all calibration adjustments and sensing electronics.

Whenever the LS7000/2 is used in electrically conductive materials, a coated probe (not bare steel rod) must be

used.
