Tuning fork type level switch11/20/2023 Versatility : can be applied to various conductive and non-conductive media measurement, such as liquid, viscous, granules, powders Fly ash : can be anti-adhesion : the use of patented anti-adhesion circuit can eliminate the adhesion of the material generated false signals. In addition, the level switch to new technologies and the use of foreign imported chips, has a long life, stable performance, safe and reliable, and adaptable ( different electrical parameters measured medium density shall not affect the measurement ), without adjustment ( regardless what the media do not require on-site measurement calibration ) and freedom from maintenance, which is widely used in metallurgy, building materials, chemical industry, light industry, food and other industries in the level of process control. As the tuning fork level switch basically no moving parts, mechanical wear comparison, it is therefore no maintenance and adjustment, easy to use. Suitable for almost all liquid media, but also suitable for measuring free-flowing medium-density solid powder or granules. This frequency change detected by the electronic circuit and outputting a switch. When the tuning fork is liquid or solid immersion, the tuning fork vibration frequency and amplitude will change. Simply put, the piezoelectric crystal tuning fork excitation produces mechanical vibrations which has a certain frequency and amplitude. Rod sensitivity due to induction from the front to the rear turn weakened the natural principle, so when material inside the tank around with buckets stacked up, touching sensor bar stand or when nesting, will not generate an error signal. When the material in contact with the sensor bar, the vibration signal becomes smaller until it stops resonance, the control circuit will output electrical contact signal. It is in the tuning fork level switch sensor bar base, driven by a tuning fork piezoelectric wafer sticks, and a piezoelectric wafer acceptance by another vibration signals, the vibration signal to be recycled, and the sensor bar to resonate. ![]() It is the use of a tuning fork vibration theory designed and manufactured. This product reliability, maintenance-free, spirit High sensitivity, easy to put into operation without the need for calibration. ) often change, safety requirements Higher operating conditions can be well used, can be used for good mobility solid materials, liquid level monitoring of the material in the cement silo, powder Dusty warehouse, ash silo, tank, tanks, fermentation tanks, etc. These changes of the tuning fork level switch are measured, processed and converted into a switch signal by the intelligent circuit.Application: Widely Material: Stainless Steel Power supply: DC24V or AC220V 50/60Hz Propertiesįor cement, metallurgy, coal, feed, grain, steel, power plants, sewage treatment, food and beverage, pharmaceutical and other lines Industry, especially in the conductive material, material properties ( state, humidity, dielectric constant, density, etc. When the tuning fork of the tuning fork level switch is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. The working principle of the tuning fork level switch is to make the tuning fork vibrate at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. Tips: Working Principle of the Tuning Fork Level Switch. ![]() Tuning fork type level switch is widely used in chemical surveying, power plant surveying, reservoir surveying and medicine tank surveying. Factory price level switch with multi-function panel, aluminum alloy shell and the protection grade is IP67.
