Overview
The working principle of a tuning fork level switch is to vibrate the tuning fork at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork comes into contact with the measured medium, its frequency and amplitude will change, and these changes will be detected, processed, and converted into a switch signal by an intelligent circuit.
Product Details
ZYK640 tuning fork level switch has the advantages of long service life, stable performance, safety and reliability. It can be used to measure medium density solid powder or particles that can flow freely, and can also measure various liquids compatible with fork body materials, free from foam, vortex, gas and other factors. Mainly widely used in the process control of material levels in industries such as metallurgy, building materials, chemical, light industry, and grain.

When installing the sensor, insert it into the tank and use a wrench to tighten the hexagonal thread on the upper part of the sensor. Be careful not to twist the blue housing, as it may cause rotation between the blue housing and the probe rod during the tightening process. At the time of leaving the factory, the connecting cables between the electronic unit and the sensor inside the shell have been connected. Forcefully twisting the shell will cause the internal connecting cables to break;
2. During installation and construction, be careful not to subject the fork to strong impact to avoid damaging the piezoelectric crystal;
3. Instrument sensors should avoid the impact of materials as much as possible. When installed horizontally, the two parallel fork plates of the fork body should be perpendicular to the ground (at this time, the direction mark of the fork body should be raised or lowered) to ensure that materials can easily flow out between the fork plates.
