No Calibration Required.
The VR Series Vibrating level sensors are piezoelectric devices. Thus, the unit can be used for high and low level indication, or plugged chute detection. Used for material densities from less than 2 lbs/cu.ft. including carbon back, plastics, fly ash, feed, seed, grain, food, chemical, and other materials. It detects extremely light, fluffy materials and materials with low dielectric constants.
The unique blade level probe design specifically combats build up on the probe, eliminating false alarms common with other piezoelectric devices. The fail-safe indication is high/low switch selectable.
