PULSE POINT™ LP-500ST

The LP-500ST is a vibrating rod used for level measuring. This series of vibrating rod level switches are robust instruments designed for low and high level indication of granules and powders with a minimum of 3.12 lb/ft2 (0.05 kg/dm3) density. The LP-500ST is a vibrating rod that senses material using a mechanical principle and is not affected by the dielectric constant of the material. This makes it an ideal sensor in plastics, dust, shavings, cement, lime, sand, grain, feed, sugar, and many others.

The LP-500ST technology is based on a vibratory technology where the electronic circuit excites the vibration in the rod or probe. When the material reaches and covers the rod vibration stops, when the material leaves the rod it returns to vibrate freely. The electronics senses the change of vibration and gives output signal after a selected delay.
