Description for Nohken VC Series Vibrating Level Sensor
VC12NVC12FCompact with 175mm detector and robustIdeal for small to medium size hoppers or pipe insideStable operation based on coil impedance detection.Resists temperatures up to 150? as standardUniversal power supply (100 to 240V AC)Principle of OperationMeasurement is based on coil impedance detection. A magnet and an electromagnet inside the detector vibrate the plate. Current that flows on the electromagnet decreases when the detector is covered by the measured solid. The sensor detects this change to determine solid presence and gives an output.When the detector is not covered by the materiaThe 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.Recommended Products For Nohken
