Tuning Fork Level Sensor VQ

VQ is a compact level sensor ideal for integration into machinery. Wetted parts, the fork and process connection, are 316L stainless steel to offer high corrosion resistance. The cover has a window. The user can check operation status through it by LED without opening the cover. The fork assembly incorporates a piezo-electric crystal. This crystal oscillates the detecting element, the fork, at a frequency. The frequency changes when the fork is covered by the material. The electronics of the sensor detects this change in frequency, and gives an output for presence or absence of the material.
