FPS Tuning Fork Level Switch

The FPS series tuning fork level switch uses a piezoelectric body and the natural frequency of the tuning fork to vibrate the tuning fork. For this frequency change, continuous monitoring can be carried out. When the tuning fork level switch is used for low alarm (or low control) purposes, the medium in the container is discharged downward and flows through the tuning fork. When it is below a specific position of the fork body, it causes a change in the natural frequency, which is detected by electronic components and switches the output state; When used for high alarm (high-level control) purposes, the medium inside the container rises and comes into contact with the fork body of the tuning fork, and the output state can be switched. The natural frequency of the tuning fork is selected to prevent interference from equipment vibration, which may cause erroneous switching actions. The length of the tuning fork is short, which minimizes the length that can be inserted into the container or pipeline. Due to the design of the product using short fork technology, it can actually be used in all liquid applications and situations with good fluidity. A large amount of research has made the tuning fork design achieve the highest operating efficiency, making the product suitable for almost all liquids, including coating liquids (eliminating tuning fork adhesion overlap), inflatable liquids and slurries, as well as powders with good fluidity and no adhesion The tuning fork level switch, also known as an electrical float, can be used in situations where a float level switch is used or where a float level switch cannot be used due to structure, turbulence, agitation, bubbles, vibration, or other reasons. Due to the lack of moving parts, the tuning fork level switch does not require maintenance and adjustment, and is an upgraded product of the float level switch. Fork level switches are widely used in industries such as petrochemicals, light industry, food, and water treatment to provide upper/lower limit alarms and automatic control of the level.
