LS6000 Basic Features Level Sensor

The LS6000 is an excellent general purpose level switch. This unit can sense all liquids and difficult to measure dry materials. The LS6000 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.

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 LS6000 is activated and gives the desired output.

The standard probe is made of a solid 316 stainless steel rod, 1"NPT process connection and Delrin insulator. Teflon and 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.

Customer Testimonial

“Babbitt International’s level switches have been a life saver. We are now using these level switches on all of our oil storage tanks, some to control pumps and others to indicate oil level. Their customer support has been as awesome as their well-made products.”

Eric Cox -Mechanical Eng. Technician
VanTran Industries, Inc.

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 LS6000 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. Special materials of construction are available. Please consult factory.
