2Tiankang tuning fork level gaugeprinciple

This product is a liquid point level switch designed using the tuning fork principle Use piezoelectric crystals to vibrate the tuning fork at its natural frequency Continuous monitoring can be conducted for this frequency variation When the product is used for low reporting, the liquid in the container is discharged downwards through the tuning fork, causing a change in the natural frequency, which is detected by electronic components and switches the output state. When used for high reporting, the liquid in the container rises and comes into contact with the tuning fork, and the output state can be switched.

4.1 Instruments are generally installed vertically, horizontally, or diagonally with a fork end facing downwards (when the material adhesion is strong, it is recommended to use a fork end facing downwards vertically).

4.2. The instrument is not allowed to be installed upside down, i.e. with the fork end facing upwards.

4.3 When there are lumps or hard particles mixed in the material, it is recommended to use vertical or inclined installation methods.

4.4 Before installing on the equipment, it is recommended to use a small amount of medium sample to test and calibrate sensitivity. For example, immersing the instrument into a container containing a medium to test the reliability of the switch.

4.5. In actual installation, it is generally divided into top installation (high-level monitoring of the medium), side wall installation (high-level or low-level monitoring of the medium), and pipeline installation (air flow monitoring of the material pump).

Precautions

1. Avoid material adhesion and prevent the vibration of the fork.

2. In the case of scarring, sufficient space should be left between the fork and the tank wall.

3. Instruments used for liquid level monitoring, with detection points determined according to the height required for monitoring or control.

4. For low viscosity liquids, the tuning fork head can be freely separated from the process medium and installed at any position as shown in the diagram.

5. For high viscosity liquids, the tuning fork head cannot be freely separated from the process medium, and it is recommended to only install the fork end vertically downwards.

6. For instruments used for level monitoring, the installation position of vertical cylindrical containers or similar containers depends not only on the level height that needs to be monitored or controlled, but also on the resting angle and feeding position of the material When installed horizontally, the fork end should be located one-third of the container radius away from the inner wall of the container; Two forked stocks should be in the same horizontal plane When installed vertically at the top of the container, the distance between the installation center and the inner wall of the container should be selected at one-third of the container radius The installation position of instruments should be designed to avoid direct impact or flying of material flow To avoid causing incorrect actions and wear, if it is impossible to avoid material impact or splashing, a protective eave can be installed above the instrument installation position. The effective width of the protection should be greater than the fork end width, and its length should be greater than the actual size of the instrument penetrating into the silo.
