LS7000 LEVEL SWITCH
1. DESCRIPTION
A. General Description
The LS7000 is a point level switch that detects the presence or absence of material in a bin, silo, tank or other
container. 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. The unit is calibrated
in the absence of material and an internal relay changes state when material is detected.
