#Fork type level switch series

The LTUM-2000 Series can operate in temperatures up to 120☌ (248☏) and all have a maximum working pressure of 725 PSI (50 bar). All models are made with 316 Stainless Steel and are available with PTFE coatings or tri-clamp fittings for sanitary applications. This change is detected by the integrated oscillator and converted into a switching output. When the tuning fork is submerged in the product, the frequency changes. The switch vibrates at a resonant frequency.

The LTU-2000 Series is based on the vibrating tuning fork principle, using piezoelectric crystals. They are also suitable for mining, chemical processing, and food and beverage applications.The LTU-2000 Series Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids. The models are easy to use and are ideal for controlling powders and fine-grained vibrating fork solid. What is the use of tuning fork level switch?Ī tuning fork level switch for solids is a sensor that generates an electrical contact at a certain level. The threshold frequency is set to match the natural frequency of tuning fork type level switches under water. When the amplitude drops below a set threshold, the onboard electronics changes the outputs (relays).Īs the tuning fork type level switch is covered with liquid application media, its natural frequency decreases. It is important to consider the type of application media when monitoring given parameters.ġ.Amplitude of vibration: Vibrating Level Switch for SolidsĪs the material level increases and comes into contact with the Vibrating Fork tines, the amplitude of oscillation of tuning fork level switches dampens. The vibrating fork type level switch working principle is based upon detecting the change in harmonic vibration frequency of the sensing element as a result of. Vibrating fork level sensors operate by vibrating tuning fork sensors continuously at their natural frequency and detecting the change in frequency and amplitude when application media is present. Maximum and minimum level detection in tanks containing different types. It may sometimes have a voltage-free contact, or sometimes it may have a fixed voltage of 0-12. The Rosemount 2120 Vibrating Fork Liquid Level Switch is designed for use in. A level switch's output can be voltage dependent or not, depending on the device. In the event of a variation in the level, the device raises an alarm or produces a sound. It works like any alarm switch that turns on/off when the level of fluid goes above or below a predetermined level. This prompts it to actuate an alarm, pump or valve. China Tuning Fork Level Switch catalog of Vibrating Tuning Fork Level SwitchVibration Fork Sensor Level Switch, Vibration Tuning Fork Level Switch Liquid. When the forks are exposed to liquid, the frequency drops and this is detected by the switch electronics. The unique fork design and inherent vibration characteristics of the fork type level switch can guarantee the automatic removal function. These models also feature two forks that vibrate at their mechanical resonance frequency, allowing them to self-clean when they come into contact with air. Our tuning fork type level switch is suitable for almost all liquids, including coating liquids, aerated liquids and slurry, as well as powders with good fluidity and no adhesion. As it contacts the material in a tank, its oscillation stops, prompting the switch to output a detection signal. Vibration type level switches are composed of a vibrating rod made from stainless steel. It is the most widely used product in the material (liquid) level switch instrument.

The product can adapt to the harsh working conditions and work reliably. When the vibrating fork for pharmaceuticals is subjected to medium damping, the v ibrating fork stops vibrating, and the control circuit drives the relay to send out a switch signal. The vibronic sensor detects the level of solids, granules and. The sensing part for detecting the material (liquid) level is composed of the vibrating fork for liquids, which has a fixed vibration frequency and amplitude vibration. Vibrating fork type level switch based on tuning forks amplitude measurement principle. Profile Wireless Value Proposition Careers. Choose relay or SSR tuning fork level switch output. The Vibrating Fork Level Switch is designed using the principle of the damping effect of the medium on the v ibrating fork vibration and the piezoelectric effect. Tuning Fork Switch can be used for high or low level detection applications.
