|The Pulse Point™ is an electronic vibratory level control especially effective in lightweight powders and granular solids. Because the pulse point™ senses material using a mechanical principle, the dielectric constant of the material is irrelevant. Remote models are available for high temperature or high vibraton applications.
LP-30 includes dual conduit entry for ease of installation as well as the separation of input wiring and alarm wiring. The LP-100 is a self contained level switch with extermal lights, magnetic test fob feature and a remote counterpart, LP-200.

How the pulse point™ works:
The pulse point™ uses a vibrating "tuning fork" to sense the presence of material.
Piezoelectric crystals [A] in the base of the fork create and sense movement of the tines [B].The electronics [C] and transmit crystal drive the oscillation, and when in air the times vibrate at about 100Hz.
When material contacts the fork tip, the oscillation diminishes because the fork is now dampened by material contact.
The receive crystal senses this difference and changes the state of the output relay.
