The Model VHS vibrating rod level sensor from BlueLevel Technologies is now available in a pipe extended version with overall insertion length ranging from 18 to 118 inches, which makes it ideal for top mounting installations where the advantages of no calibration and solidstate technology are desireable, according to the manufacturer. The Model VHS Rod pipe extended unit has a universal AC/DC power supply, low density detection capability to as lightweight as 3.12 lbs/ft3 and is of a high quality design and manufacture. 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. The built-in SPDT relay is fail-safe on power failure and a local bi-color LED indicator of normal/alarm status, all stainless steel wetted part construction, rugged NEMA 4X enclosure suitable for ordinary electrical locations, and an affordable price are all standard features. The VHS Vibrating Rod will operate with process temperatures as high as +130 C.
