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.
“Here at EnviroCare International, we design and build wet scrubbers for industrial and municipal customers along with scum concentrators for the sewage treatment industry. Level detection in concentrated sewage scum is especially challenging due to the sticky, viscous nature of the media and the variable amount and type of solids. A high level switch needs to be tuned to ignore splatter and buildup. A low-level switch needs to be able to detect a slight void developing before the scum pump creates a bridge over the hopper and runs dry. Buildup on the low level switch is inevitable so it needs to change state when the probe becomes even the least bit un-submerged. EnviroCare has found that not only does the Babbitt LS7000 have the tuning span to handle either situation but the tuning potentiometer (along with the rest of the device) is rugged and ready for in-the-field tuning. Having worked with other less rugged level devices in the past, EnviroCare has been pleased with the performance of the LS7000 level switch and it has become our go-to device for point level detection across our entire portfolio of engineered products.”

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.
