LS2000 Low-Cost Level Sensor

The LS2000 is a simple, low cost point level switch that provides reliable level detection in a wide variety of liquid and dry materials.  Unlike mechanical devices, the LS2000 level switch has no moving parts to wear out, jam or break, significantly reducing the need for regular maintenance and cleaning.  Calibration is a snap, one piece design makes installation quick and easy.  Proprietary radio frequency (RF) technology provides excellent level measurement and stability while having the ability to ignore significant product buildup, thus eliminating the need for recalibration.

Overview

When the probe is installed, it is calibrated in absence of material touching the probe. When the desired material comes in contact with the probe, the relay switches and gives the desired output.

The standard probe is made of a solid 316 stainless steel rod, ¾" NPT process connection and the insulator is made of Ultra-High Molecular Weight Polyethylene (UHMWPE). Teflon insulators are optional. UHMWPE has excellent abrasion and impact resistance while the optional Teflon insulators allow for high temperature operations. The standard seals are made with Viton "O" rings. All the electronics are housed in a cast aluminum explosion-proof enclosure.

The solid stainless steel rod is available in a variety of lengths and is suited for liquids or bulk solids. These probes can be coated with Halar in lengths up to 72 inches. A blind-end probe option is also available for applications where a wet material build-up may foul a horizontally mounted probe.

The blind-end unit has no visible probe because the insulating material completely covers the sensing probe. All the necessary calibration indicators are on-board so all you need to calibrate the LS2000 is a small screwdriver.

Fail-safe electronics provide peace of mind. The modular electronics make trouble shooting and repair a snap. The entire unit is backed by our two year warranty, 60 day money back guarantee. Other materials of construction are available. Please consult factory.
