March 9, 2011 - BlueLevel Technologies introduces a vibrating fork point level sensor for detecting ULTRA-lightweight bulk solids. The Vibrating Fork unit will detect the presence and absence of material as lightweight as 0.624lbs/ft3. It will operate with powders that are dry and free-flowing as well as granular materials, to provide reliable high, low and intermediate level control.
The VHS Vibrating Fork incorporates a universal AC/DC power supply, SPDT relay that is fail-safe on power failure, a local bi-color LED indicator of normal/alarm status, all stainless steel wetted part construction, a rugged NEMA 4X enclosure suitable for ordinary electrical locations, and an affordable price. The VHS Vibrating Fork will operate with process temperatures as high as +130°C (266°F). “The Vibrating Fork is a new addition to our Model VHS vibrating element point level sensor product line for solids”, says Joe Lewis, Managing Director. It uses piezoelectric technology to create its 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.
