SLM: Vibrating Fork Level Sensor

Item Code: SLM

Vibrating Fork Level Limit Switch for free flowing Solids, Granules and Powders
  • Application Temperature Range : up to 250° C
  • Calibration Free, Independent of Materials Di-electric Properties
  • No moving parts longer running life
  • Certifications: Flame Proof Housing IIA & IIB

Principle
A specially shaped tuning fork is kept vibrating using piezo-electric elements. The oscillation of the fork damps when in contact with the material. The loss of oscillation amplitude is detected and used for switching a relay. The output contacts of the relay are in turn used for annunciation or control.

Benefits
  • Suitable for detection of underwater chips
  • Configured for high and low level fail-safe detection.
  • Non-stick PTFE/Halar coatings are also available for special applications.
  • Variation of electrical characteristics of the service material such as conductivity and dielectric constant do not affect its operation.
