The vibrating rod/tuning fork level switch is a new type of switch, which is excited by a crystal. Vibration, also known as “electrical float”, is not affected by dielectric parameters and factors such as turbulence, agitation, bubbles, vibration, etc. There are no moving parts, so maintenance and adjustment are not required, which is complex. Ideal for level switches in working conditions. Where a float switch is used and due to structure, turbulence, It can be used in occasions where the float level switch cannot be used due to agitation, air bubbles, vibration and other reasons.
Measurement principle
The tuning fork level switch is used to detect liquid media, and the vibration element (tuning fork) is under pressure. Driven by the electric ceramic, it vibrates at a certain mechanical resonance frequency. Once the vibrating element is connected. When the measured medium is touched, the vibration frequency will change. The electronic circuit detects this vibration frequency rate changes and convert them into switching commands, even if the external vibration is strong or the measured medium is more change, the measurement will not be affected. The vibrating rod level switch is used to detect solids. Over piezoelectric drive When the vibrating rod touches the medium, the amplitude is attenuated, and the electronic circuit detects the vibration. Measure the amplitude of this attenuation and convert it to a switching signal, due to the rod type structure, no media adhesion or jamming, etc., and easy cleaning makes it easy to use. For food and pharmaceutical industries, installation position and particle size do not affect measurement stability. It is very easy to install and debug. It can be debugged without material. The measured medium can be plastic. Pellets, milk powder or slices, etc.

Application Features
Strong adaptability – – -Single bar type can prevent material clamping and sticking, and can still be used when there are many hanging materials Stable work, not affected by the measured medium parameters, material variety changes, humidity changes Does not affect sensor operation.
High sensitivity – – -Can measure materials with very small specific gravity.
Maintenance-free – – – The detection process of the switch is completed by the electronic circuit, no moving parts, safe No maintenance required for shipment.
No need to adjust – – -The detection of the limit switch is not affected by the parameters and density of the measured medium,No on-site adjustment is required for measuring any medium.
