Parameters of tuning fork level switch

 image.png

The working principle of the tuning fork level switch is to vibrate the tuning fork at a certain resonant frequency by the piezoelectric crystal. When the fork of the tuning fork is in contact with the medium under test, the frequency and amplitude of the tuning fork will be changed and converted into a switching signal

Application examples

1.To prevent overflow

Owing to overheating caused by the overflow of the human body and the environment harm, resulting in loss of production and increase the cost of cleaning. The device is a limit switch for providing an overflow signal at any time.

2.High and low level alarm

The product is ideal for storing the highest and lowest liquid level tests for a wide variety of liquid tanks. Rugged equipment can run continuously at temperatures up to 150 C and operate at pressures up to 100 bar, especially for high level or low level alarms.

3.Health application

Due to the highly polished tuning fork provided by the surface finish of 0.8um, the product has a strict requirement for the basic design of food and pharmaceutical applications. As a result of stainless steel, with sufficient durability, can withstand high temperature 150C.

Application and features

Suitable for measuring medium-density solid powders or granules that can flow freely. Also suitable for almost all liquid media, this series of tuning fork level switch can measure a variety of level, with high/low failure safety limit switch, overflow or dry run protection, pump control, showing the presence/absence of flow in the pipeline, etc. Features.

Tuning fork switch can measure a variety of level, with high / low failure safety limit switch, overflow or air running protection, pump control, display pipe with / without flow and other functions.

Tuning fork switches are mainly used for challenging liquids, including layers, contaminated waste water and hydrochloric acid, and industrial liquids such as sodium hydroxide.

The tuning fork switch has a variety of output formats, 2-wire AC, 2-wire DC, and 3-wire PNP/NPN transistors. The operation of the tuning fork level switch is independent of the conductivity, dielectric constant, viscosity, pressure and temperature of the liquid.
