The Model VHS vibrating rod level sensor is now available in a pipe extended version with overall insertion length ranging from 18 to 118 in., making it suited for top mounting installations where silo operators realize the advantages of no calibration and solid-state technology.
The Model VHS Rod pipe extended unit has a universal AC/DC power supply, low-density detection capability to as lightweight as 3.12 lb./cu. ft. It will operate with powders that are dry and free-flowing as well as free-flowing granular materials, to provide reliable high, low and intermediate level control.
It uses piezoelectric technology to create its harmonic vibration in the absence of material. When material is present the vibration is dampened and the sensor relay output changes state to indicate material presence. — BlueLevel Technologies, www.blueleveltechnologies.com
