Tuning fork level sensor 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. Overall, vibrating fork level switches offer a reliable, accurate, and cost-effective solution for solids level measurement in a wide range of industries, including food and beverage, pharmaceuticals, plastics, and mining.The LTU-2000 Series Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids.

Vibrating fork level switches offer several advantages for solids level measurement: They are also suitable for mining, chemical processing, and food and beverage applications. The models are easy to use and are ideal for controlling powders and fine-grained vibrating fork for solids. What is the use of tuning fork level switch?Ī tuning vibrating 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. Vibrating fork level sensors operate by vibrating tuning fork level sensor continuously at their natural frequency and detecting the change in frequency and amplitude when application media is present. It may sometimes have a voltage-free contact, or sometimes it may have a fixed voltage of 0-12. 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. Vibrating fork level switch working principle: This prompts it to actuate an alarm, pump or valve. When the forks are exposed to liquid, the frequency drops and this is detected by the switch electronics. 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. 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 vibrating fork for solids stops vibrating, and the control circuit drives the relay to send out a switch signal. 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. The vibrating fork level switch for solids is designed using the principle of the damping effect of the medium on the v ibrating fork vibration and the piezoelectric effect.
