Vibrating Solutions for Bulk Solids

The Pulse Point LP-500ST is a robust, vibratory level single rod instrument designed for low and high level indication of granules and powders with a minimum of 3.12 lb/ft² (0.05 kg/dm³) density. Being a single rod, it is ideal for large granules because there is no potential for the granules to become jammed.

Application Variety

Having a universal power supply permits AC or DC wiring, and because of the mechanical nature of the LP-500ST it is not affected by the dielectric constant of the material.


Adjustable and Easy to Install

The process connection is a standard 1-1/2″ NPT connection, and both the time delay and fail-safe are field selectable to adjust to changing environments or materials.

Multiple Configurations

The LP-500ST is available for standard temperatures up to 230°F (110°C), for high temperatures up to 320°F (160°C) or with extensions, either pipe or cable.
