Principle of Operation

Principle of Operation
Measurement 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 material. The sensor detects this change to detect solid presence and gives an output.

When the detector is not covered by the material

  • The 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 magnet
  • The sensor determines the detector is not covered by the material.

When the detector is covered by the material

  • Applying 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.
Vibration: Point level measurement with vibrating level switches | VEGA In point level measurement with vibrating level switches, a rod or a fork is set vibrating. When the vibrating probe comes into contact with the medium, the vibration changes and the vibrating level switch outputs a switching command. Vibrating level switches are used as overfill protection devices or low-level indicators in ...

Vibrating Fork Type Level Switch Working Principle Vibrating fork type level switch working principle is simple and very reliable whether for sensing the presence of liquids or bulk solids. Type 8110 - Vibrating level switch The 8110 is a vibrating level switch for liquids, using a tuning fork for level detection. It is designed for industrial use in areas of process technology and can be used in liquids. Typical applications are overfill or dry run protection. The small tuning fork (40 mm in length) can be used in vessels, tanks and pipes. Due to the ... Level Sensors, Level Indicator, Vibration Switch, Level Measurement  Gladiator Vibration Switch. Principle of Operations. A stainless steel tuning fork is driven by piezo ceramic elements, causing it to vibrate at its resonant frequency. When the material to be detected covers the fork, vibrations are damped. The changed vibration is sensed electronically, and the processed signal is used to ...

Vibrating Fork Level Switch - Level Vibrating Fork Level Switch RS85. The Resonator utilizes a piezoelectric driven tuning fork that exhibits a large change in resonant frequency when immersed in any liquid. A "smart" microprocessor-based electronic unit keeps the sensor in a resonant state as it changes from dry to wet or wet to dry. Overview. Data. Rosemount™ 2120 Level Switch - Vibrating Fork | EMR The Rosemount 2120 Level Switch provides easy to install, reliable level detection and control. 3rdparty IEC61508 (SIL2) safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications. It has no moving parts, needs no calibration and is virtually unaffected by process conditions. Vibrating Rod – BinMaster Vibrating Rods—also know as vibrating level switch—are a reliable point level sensor used for high and low-level indication or plugged chute detection. They can be used in light, fluffy powders and flakes with bulk densities as low as 1.25 lb/ft3. BinMaster vibrating rods feature a unique, sword-shaped probe that resists ..
