LS8000/2 Mulit-point Remote Mounted Level Switch

Description

The LS8000/2 multi-point RF level switch can measure virtually any liquid, dry material or interface of electrically conductive or non-conductive products. The proprietary radio frequency (RF) balanced impedence 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.

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 setpoint outputs.

For highly conductive materials such as water, a Halar coated probe is required.

For best results, this unit should be applied in homogeneous liquids when configured for multiple setpoints on one probe.

Calibration

All the necessary calibration indicators are on the receiver 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.

Construction

The probe is made of solid 316 stainless steel rod and the insulator is made of Teflon. A Halar coating is required for electrically conductive liquids. 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.
