Description for Nohken VF Series Vibrating Level Sensor

VF10-65   VF10-80  VFS10-65  VFS10-80VFS1000Flat vibration plate of 1 mm in thicknessRobust and shock resistantEasy installationDetection based on “pulse vibration method”Wide sensitivity adjustable rangeFail-safe functionalityUniversal power supplyMaximum 200 meter separation distance (VFS)Principle of OperationThe sensor has a magnet and an electromagnet fixed on the vibration plate. When current is applied to the electromagnet, repulsive force of the magnet causes the plate to vibrate.When the material covers the plate, vibration decreases, causing lower voltages to be induced in the electromagnet. The sensor detects the voltage change to determine material presence.When the detector is not covered by the materialhe electromagnet vibrates at its operating frequency when alternating current is applied.Back electromotive force on the electromagnet becomes the largest due to change in magnetic field from the magnetThe sensor determines the detector is not covered by the material.When the detector is covered by the materialApplying alternating current does not cause the electromagnet to vibrate at its operating frequency.No back electromotive force occurs because the magnet is stationary.The sensor determines the detector is covered by the material.Inside the housingCompact version Remote version
