Model VHS Level Sensor
The Model VHS vibrating rod level sensor is now available in a pipe extended version with overall insertion length ranging from 18 to 118 feet. The Model VHS Rod pipe extended unit has a universal AC/DC power supply, low density detection capability to as lightweight as 3.12 pounds/sq. foot. It uses piezoelectric technology to create 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 and rugged NEMA 4X enclosure suitable for ordinary electrical locations are all standard features.
