Vibrating level switch / for liquids - VTK-R series
The Sitron V-Tork series of level switch tuning forks uses piezo-electric crystals to vibrate at fixed resonant frequency levels. Whenever tuning forks are submerged mediums, vibrating frequency rates change. The changes are identified by the forks' electronics systems, and converted into switch outputs (either relay SPDT or PNP/NPN). The V-Tork Tuning Forks are integrated with red LED indicators within their housing structures. These indicators blink whenever the devices are in contact with products. They are constantly on, ensuring users that the apparatuses are always operating.
All models of the V-Tork series are engineered out of 316-grade Stainless Steel materials. They are available in either Halar or epoxy coating finishes, complete with hygienic fittings. This allows the tuning forks to provide sanitary operations.
