June 20, 2013 - The Model VHS Vibrating element point level sensor line includes a Fork and Rod version in short, standard and extended lengths for the widest range of applications in powder and bulk solids. Granular, free-flowing powders and a material density range from 0.624lbs/ft3+ make the Model VHS product line an excellent choice for nearly all powder and bulk solid applications. The Model VHS is a level control sensor using piezoelectric technology to create its harmonic vibration in the absence of material. When material is present at its probe the vibration is dampened and the sensor relay output changes state to indicate material presence.
The Model VHS is ideal for easy to difficult applications including those with ultra-lightweight materials and for bins with changing materials where calibration needs to be eliminated. The Model VHS point level standard sensors work with process temperatures as high as +110°C (230°F), and an optional high temperature design is also available for use with process material temperatures up to +160°C (320°F). Other features include a universal AC/DC power supply, relay output fail-safe on power failure, a rugged NEMA Type 4X powder coated aluminum enclosure, and local LED indication of material alarm condition.
