LS7000 Full-Featured Level Sensor

The LS7000 has features that make it the most versatile level control switch on the market today. This unit can measure virtually any liquid, dry material or interface. The LS7000 employs a radio frequency (RF) balanced impedance bridge to sense the presence or absence of products. This technique provides the ability to ignore significant product build up on the probe and it is very stable over wide temperature swings, thus eliminating the need for recalibration.

Every standard unit has an on-board fuse and surge suppressor to protect the circuitry from power surges. Additionally, a static suppression circuit protects against hostile bin environments created by static-prone materials such as plastic pellets.

The built-in timer allows the user to select ON DELAY or OFF DELAY operation if desired. The timing range is adjustable from 1/8 second to 2 hours. The timer can be used to ignore wave action in a turbulent vessel, or the timer can be used to pump down a sump with a single probe.

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 LS7000 is activated and gives the desired output.

The standard probe is made of a solid 316 stainless steel rod, 1" NPT process connection and Teflon insulator. Other material insulators are optional. 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.

All the necessary calibration indicators are on-board so all you need to calibrate the LS7000 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 and 60 day money back guarantee. Flanged process connections and special materials of construction are available. Please consult factory.
