Check the listing for details. LS7000 115VAC Point Level Switch & Sensor. Condition: New. Listed at 675.00 USD. The LS7000 has features that make it the most versatile level control switch on the market today. As our most popular point level switch, this unit can sense virtually any liquid or dry material. It can even be used for liquid interface applications to detect the level of immiscible liquids that have different dielectric constants such as oil and water. The unit features an on-board test switch and built-in time delay to prevent false switching during filling or in turbulent applications. The LS7000 level switch has no moving parts making it an excellent replacement for rotating paddles, floats or other mechanical devices. The radio frequency (RF) balanced impedance is extremely stable over wide temperature swings and provides the ability to ignore significant product buildup, thus eliminating the need for recalibration. 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 level switch has a solid 10 inch 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 LS7000 is the perfect solution for high or low level alarm detection for both liquids and dry materials in tanks, vessels, silos, hoppers, bins, sumps and other containers. Other power supply voltages and/or probe lengths available - contact factory.
