9/23/2023 0 Comments Tuning fork level sensor![]() These changes of the tuning fork level switch are measured, processed and converted into a switch signal by the intelligent circuit. The vibrating level switch of the LFV200 product family detects the pre-defined levels in liquid systems with maximum precision. 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 monitoring process of given parameters depends upon type of application media. When the fork is immersed in liquid or slurry, the vibration ceases. The working principle of vibrating fork level sensor is based on vibrating a tuning fork sensor continuously at its natural frequency and detecting the change of frequency and amplitude in the presence of application media. In solids a one-rod sensor is excited at its resonant frequency. The change is analyzed and translated into a switching signal. The oscillating frequency changes as the fork enters the medium. 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. The tuning fork vibrates at a frequency of 400 Hz in air. For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. 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. Level detection of large tanks and water treatment plants. Wetted parts, the fork and proces Electrode level sensor for liquid fluid. Solid materials: fly ash, cement, stone powder, plastic particles, salt, sugar, etc.Factory price level switch with multi-function panel, aluminum alloy shell and the protection grade is IP67. Vibronic point level instruments, popular since the 1980s, can now diagnose themselves, meet safety requirements and support Industry 4. VQ is a compact level sensor ideal for integration into machinery. Measuring medium: dry particles, powdery materials and various liquids, slurries, etc. It is not affected by foam, eddy current and gas, and is suitable for fixed-point alarm or control of solid material levels in various silos and liquid levels in various containers. It is mainly used in metallurgy, building materials, chemical industry, light industry, grain and other industries. From Temecula, California, United States. Tuning fork level switch has the characteristics of long service life, stable performance, safety and reliability, as well as strong adaptability, no adjustment and maintenance-free. Tuning Fork Level Switch Flanged 24 VDC Explosion Proof Approx. ![]() ![]() The change is analyzed and translated into a switching signal. The Tuning Fork Sensors are based on the principle of dual tuning forks, which vibrate at low frequencies. Its unique fork body design and its inherent vibration characteristics can ensure the automatic cleaning function of the tuning fork and prevent material hanging to the greatest extent. For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. A 'smart' microprocessor-based electronic unit keeps the sensor in a resonant state as it changes from dry to wet or wet to dry. Tuning fork Type Level Switch uses a metal tuning fork structure to detect the presence of a liquid or solid in a vessel. The working principle of the switch is to cause its vibration through the resonance of the piezoelectric crystal. It mainly uses the resonance principle of tuning fork to measure the level state. The resonator utilizes a piezoelectric driven tuning fork that exhibits a large change in resonant frequency when immersed in any liquid. The tuning fork level gauge is a liquid point level switch tool designed by the tuning fork principle. Tuning fork level switch is a kind of level switch. Eagle Sensors & Controls - A Division of Excel Automation LLC. The tuning fork level switch is also often called the tuning fork level meter or the tuning fork level controller, mainly because the tuning fork level meter appears in different links in industrial production, and the actual key functions are different, so people are habitual called many different names.
