• Values (of performance) described in this manual were obtained under ideal testing conditions. Hence, they may differ under industrial environment and
settings.
General Instructions
• Instrument shouldn’t block the material filling inlet.
• Secure the cover of housing tightly. Tighten the cable glands. For side mounting, the cable glands should point downwards.
• For side mounting, provide a baffle to prevent the material from falling on the probe.
• When handling forks, do not lift them using their tines. While using them with solids, ensure that material size is less than 10mm.
• Deforming the shape of the tines may interfere with the fork’s operating frequency.
• Make all electrical connections as instructed in the manual. Don’t power on the device before verifying the connections.

For Hygienic Application:
Surface Finish in Ra = 0.8µm
Elixir-T-Uni is a Vibrating Fork Level Limit Switch for
liquids. It is suitable for level detection in storage tanks,
mixing container and pipelines, for all kinds of liquid which
do not react with SS 316, viscosity does not exceed
10,000 cP and temperature lies within 0◦C to 80◦C. It is
suitable for most of the applications where float switches
were previously employed, as well as in places where
float switches were not appropriate (due to deposition,
turbulence, stresses and air bubbles). Elixir-T-Uni ignores
foam deposition on its fork tines.

2 Operating Principle
Elixir-T-Uni works on the principle of continuous vibration
of the fork at its natural frequency. A specially shaped
Tuning Fork is kept vibrating by piezo electric element.
The resonance frequency changes when the tines are
immersed in any fluid.The change in frequency is detected
and used is for switching.
5 Applications
Elixir-T-Uni is suitable for the following applications and
industries:
• Chemicals
• Pesticides
• Edible Oil
• Food Industry
• Dairy Industry
• Packaging Industry
• Pharmaceutical
• Breweries

3 System Description
Elixir-T-Uni vibrating fork level switch detects the resonant frequency change and changes the output signal
according to fail-safe mode selection. Typically, the output
is fed to a PLC which then uses it to control the process.

order mentioned below -
Procedure for Installation
For quick and easy installations, follow the steps in the
• Remove the female socket from the top of Elixir-T-Uni
(Use Screw Driver) and you can see that there are four
pins of male socket on Elixir-T-Uni.
• Remove the cap from the female socket by using screw
driver.

Table 4: Error Indications
• When Red LED blinks continuously and Fail-safe is High
• When Green LED blinks continuously and Fail-safe is Low
Troubleshooting: The following reasons may be responsible for the absence of vibrations in the fork:
• The instrument is damaged.
• The instrument is working but there may be solid particles in the application medium clogging the fork.
• Heavy build-up of application medium can dampen the fork oscillations. In this case, the fork requires to be cleaned.
• If material is very viscous, the fork vibrations will resume when the fork is uncovered. In this case, the error
indication should be ignored.
3. No LED Glows
• This would happen in absence of power supply to the instrument.
