Vibrating rod point level sensor for solids detection

Pipe-extended configuration from BlueLevel Technologies allows for a wide range of insertion lengths.


Pipe-extended configuration from BlueLevel Technologies allows for a wide range of insertion lengths.The Model VHS vibrating rod level sensor from BlueLevel Technologies is designed to detect the presence of solid materials so as to serve as a level switch. It operates 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 can detect low-density products down to 3.12 lbs./cubic ft.

“The Model VHS is now available in a pipe extended version with overall insertion length ranging from 18” to 118” says Joe Lewis, BlueLevel managing director. “This makes it ideal for top mounting installations where the advantages of no calibration and solid-state technology are desirable”.

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. Features include:

• Built-in SPDT relay is fail-safe on with power loss
• Local bi-color LED indicator of normal/alarm status
• All product contacting parts are stainless steel
• Rugged NEMA 4X enclosure, and
• Operating temperature up to 130 °C (266 °F).
