LS8000 LEVEL SWITCH
1. DESCRIPTION
A. General Description
The LS8000 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 is a transmitter that is connected to the receiver board by a twisted, shielded pair of 
wires. 
The receiver board may be mounted up to one mile from the probe. All calibration adjustments and indicators 
are at the receiver. The receiver also has the relay output and an on board fuse. 
The unit is calibrated in the absence of material and an on board relay at the receiver changes state when 
material is detected.
