The LS7000/2 dual-point RF level switch uses the proprietary radio frequency (RF) balanced impedance bridge. It is specifically designed to automatically fill or empty a tank, vessel or sump. The high and low set points are adjustable over the entire length of the probe. This unit is designed for use in homogeneous liquids.
The dual-point level switch uses a single relay and an on-board latching circuit for automatic operation. No external latching relays or holding contacts are required Simply wire the relay output in series with a pump starter or solenoid valve.
To automatically fill a vessel, select "AUTO-FILL" on the electronics, and the relay will energize when the material is below the "LOW" set point. The pump will turn on and continue to run until the level reaches the "HIGH" set point, then shut off. For "AUTO-EMPTY", the relay action is reversed.
For electrically conductive materials, a Halar coated probe is required.
All the necessary calibration indicators are on-board so all you need to calibrate the LS7000/2 is a small screwdriver. The modular electronics make trouble shooting and repair a snap. The entire unit is backed by our two year warranty.
The probe is made of solid 316 stainless steel rod, and the insulator is made of Teflon. A Halar coating on the probe is required in all electrically conductive liquids. The seals are made with Viton "O" rings. All the electronics are housed in a cast aluminum explosion-proof enclosure.
