Vital vibrating fork is a compact level switch suitable for all kinds of free-flowing solids and grains. It is ideal for applications such as over-spilling and dry run detection.
Vital is unaffected by spurious vibrations and is independent of the application material’s electrical properties.
Vital can be made with a minimum of 1 1/4″ mounting and 100 mm tines. It comes with explosion-proof housings for applications of hazardous areas.

The parts of Vital are explained in the following figure. All dimensions are in millimeters.
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 and/or control.
Resonant frequency varies with the length of tines:
|Fork Length(mm)||Min. Probe Length(mm)||Frequency(Hz)|

Namur compliance can be attained with a Namur certified isolator.

More value in less
Shorter vibrating forks – minimum insertion length of 135mm, with no compromise in operational ruggedness of the device. Saves space → paves the way for designing smaller tanks / silos.
Though vibrating forks are one of the most easy-to-install instruments, they can be sensitive to vibrations on the application silo / tank or the vibrations in the material. Vital has an intelligent noise cancellation algorithm to avoid spurious switching in case of external vibrations.
Each Elixir instrument goes through 5 test points at various stages in its production to ensure compliance with our quality and design. They also go through an early life failure test for at least seven days to ensure that only the best forks are shipped.
Reliable and fast switching with an adjustable time delay option from 0.8s to 25s.
Ensures easy cleaning, helps with stringent hygiene compliances in pharmaceuticals, dairy, and food applications.
Sapcon was the first wholly Indian manufacturer to have completely manufactured vibrating forks in India.
Vital is the latest vibrating fork from Sapcon; bettering the legacy vibrating fork models that have been successively improved and placed in the market since 1984.
Packaging plant manufacturers or OEM’s (Original Equipment Manufacturers) desire outputs suitable to the end-user’s site. Relay and PNP (Open Collector PNP) outputs though standard are generally available only in separate models. Thus, they normally had to be separately procured and stocked.
In a close understanding of our customer behaviour, we have launched a single model with both Relay and PNP output with an input power supply from 24 V DC – 265 V AC on the same two terminals. This directly results in savings by reducing the required inventory.
