November 22, 2010 - BlueLevel introduces Model VHS, a level control sensor using piezoelectric technology to create harmonic vibration in the absence of material. When material is present at its single element probe, the vibration is dampened and the sensor relay output changes state to indicate material presence. The Model VHS is ideal for detecting lightweight materials, for bins with changing materials, and where re-calibration is to be eliminated.The Model VHS standard rod probe design works with process temperatures as high as +110°C (230°F), and the optional high temperature design works with process material temperatures up to +160°C (320°F).
In addition, a universal AC/DC power supply, relay output that is fail-safe and the rugged enclosure with local LED indication of material alarm condition. Material densities as low as 0.05kg/dm3 (3.12lbs/ft3) can be detected.
