Elixir-T Vibrating Fork – for Liquids

Elixir-T vibrating fork is a compact  level switch for liquids and is used in tanks, containers and pipelines. It comes with hygienic process connection and polished finish and is hence ideal for hygienic applications. This level switch detects the resonant frequency change and changes the output signal according to fail­safe mode selection. Typically, the output is fed to a PLC which then uses it to control the process.

It is suitable for all kinds of liquids having viscosity up to 10,000 cP & density greater than or equal to 0.7gm/cc.

A specially shaped tuning fork is kept vibrating using piezo-electric elements. Typically, the fork vibrates at its natural frequency. The frequency of oscillation for the tuning fork changes when immersed in liquids. The change in frequency is detected by the microprocessor leading to a switching decision.

Forks as per your mounting

More value in less

Shorter vibrating forks – minimum insertion length of 68mm, with no compromise in operational ruggedness of the device. Saves space → paves the way for designing smaller tanks / silos.

Better immunity to external vibrations

Sapcon’s liquid vibrating forks have been successfully installed in applications where there is turbulence in the liquid and in the application tank.

100% incubated and tested → serving your application for longer

Long term reliability is the key feature of Sapcon

Reliability and Quality with Elixir-T have gone a step further than straightforward operational compliance.

A 'switch' in time saves material 'fine'

Reliable and fast switching, which in unaffected by  flowing material

Polished finish for hygienic applications

Ensures easy cleaning, helps with stringent hygiene compliances in pharmaceuticals, dairy and food applications.
