    Operating Principle

    The working principle of vibrating fork level switch is based on tuning fork’s natural frequency measurement. A specially shaped tuning fork is continuously vibrating at its natural frequency using piezo-electric elements and detecting the changes in frequency in the presence of application media. The pressure applied on diaphragm drives the tuning fork's tines apart from each other and return to their original position when the pressure is removed. As the material level increases and comes in contact with the vibrating fork tines, the frequency of oscillation of tuning fork level switch dampens or decreases as it covered with the liquid application media. The change in frequency is detected by the microprocessor leading to a switching decision. The threshold frequency is set to match the natural frequency of vibrating fork level switch under water.

    Life of Level sensor


    Brewery Production Plant

    To maintain the taste of beer over a decade appeals stringent operational conditions with hygienic pipe fittings to avoid adulteration throughout the process. These severe environmental conditions in brewery production plants provide proper aroma and taste to the beer.

    Elixir-T-Uni fork type level switch with standard hygienic surface finish (0.8 µm) is suitable in a beer manufacturing plants to prevent contamination.

    level measurement in Dairy Industry

    Dairy Industry

    Dairy processing plants engage milk for a longer period to include in other processes. Continuous processing of milk in tanks requires clean-in-place(CIP) operations to restrict contagious bacterial growth. These operations demand compact liquid measuring instruments that should be fitted in small pipelines and mixing tanks.

    The compactness of our liquid level indicator makes them flexible enough to fit in small containers. The EHEDG certification is a surplus benefit to maintain the hygiene in entire operations.

    Packaging Machines

    The Food & Beverage sector is the biggest consumer of automated packaging machines followed by the pharmaceuticals sectors. The rapid growth of the packaging industry needs an automation process sensor to sense the appropriate filling of application material.

    Our vibrating or tuning fork sensors are immune to foam build-up which not only detects the foam but also provides correct switching decisions to improve process efficiency.
