LS8000/2 Multi-Point Sensor with Remote Electronics

The LS8000/2 dual-point level switch can measure virtually any liquid, dry material (2 probe configuration) or interface of electrically conductive or non-conductive products. The proprietary radio frequency (RF) balanced impedance bridge has exceptional temperature stability, thus eliminating the need to recalibrate the unit from season to season. The LS8000 can be configured for single-point, dual-point or four-point control. The maintenance-free transmitter is mounted in the explosion-proof head of the probe. The receiver can be mounted up to one mile from the transmitter.

Overview

The LS8000/2 Dual Point is designed to be used with homogeneous fluids when configured for multiple set points on one probe. A coated probe is required for liquids with a dielectric constant greater than 12.

The LS8000/2 is specifically designed to automatically fill or empty a tank, hopper or sump. The high and low set points are adjustable over the entire length of the probe. Each receiver has 3 SPDT relay outputs. One is a latching relay for field-selectable "AUTO-FILL" or "AUTO-EMPTY" control. The other two relays provide high and low set point outputs.

The probe is made of a HALAR coated 316 Stainless Steel rod, 3/4" NPT process connection and the insulator is made of Teflon. The standard coating is HALAR, but other options such as a Teflon Sleeve are available. The seals are made with Viton "O" rings. The transmitter electronics are housed in a cast aluminum explosion-proof enclosure. The receiver board is provided with a snap-track mounting or can be purchased with an optional enclosure.

All the necessary calibration indicators are on-board so all you need to calibrate the LS8000/2 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.
