Fork type level switch8/10/2023 Insertion Length, "D" Dimension: 80 mm (3. The LTUM-2000 Series can operate in temperatures up to 120☌ (248☏) and all have a maximum working pressure of 725 PSI (50 bar). A special type called aqua fork can be used for liquids. Quartz crystal tuning forks are used in timepieces as small tuning forks to measure time. This type of level switches are suitable for fine free flow powdering and small granular materials. From acoustics to medical diagnostics, tuning forks are employed in a variety of disciplines. All models are made with 316 Stainless Steel and are available with PTFE coatings or tri-clamp fittings for sanitary applications. Tuning fork Type Level Switch uses a metal tuning fork structure to detect the presence of a liquid or solid in a vessel. This change is detected by the integrated oscillator and converted into a switching output. Tuning fork type liquid level switches New Products Tuning Fork Level Sensor VQ Series VQ is a compact level sensor ideal for integration into machinery. Furthermore, the sensor is suitable for all kinds of applications, for which a range devices based on different technologies would have been required up until. 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. Type 61 is installed directly at the switching point, 62 has an extension cable (max 80 m) and 63 is the version with extension tube (max 6 m).The LTU-2000 Series Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids. VEGAWAVE for up to 10 mm grain size, above that, VEGAVIB. Vibrating level switches are used as overfill protection or empty alarm in bulk solids, which can be either in granulate or powder form. If the vibrating probe comes into contact with the measured product, the oscillation rate changes and the vibrating level switch outputs a switching command. ![]() The basis of point level detection with vibrating level switches is a vibrating rod or vibrating fork. A downstream device can be actuated directly with this switching signal (e.g. Cost effective models are an ideal choice for level control of powders and fine grained solids. Unaffected by foam, turbulence and air bubbles. Tuning Fork level switches are sensors with an electrical contact output at a specific level. Due to its compact structure it can be used in small vessels and pipelines. The ProSense VFL Series of level switches is offered in two process connection sizes with short and extended insertion lengths, standard and high temperature constructions, and a 3-wire DC switch output for connection to controller inputs or a 2-wire AC/DC switch for control of valves and pumps. SMARTsaa offer most Compact and miniature Compact Vibrating Fork Level Switch with corrosion resistant stainless steel enclosure for liquids and slurries of density greater than 0.7 gm/cc and viscosity up to 10000 centipoise. These level measurements are indicated via an electrical switching action. Features: - Low power Microprocessor based intelligent device. Level switches are used to detect liquid or powder levels, or interfaces between liquids. It works on the principle of a change in frequency of a Vibrating Fork due to presence of a liquid/solid. It provides a switching signal on its own. ProSense Vibration Fork Liquid Level Switches. Vibrating Fork Level Switch 135-VLM is mainly for Liquids and free-flowing solids. Excited by a piezoelectric crystal tuning fork Reed vibration, liquid or solid when. it can be operated without external evaluation. Tuning fork level limit switch is a common type of level limit switch. The instrument is connected with standard cable. The instrument only has to be mounted in such a way that the vibrating element is at the height of the desired switching point. The level switch can be installed in any position. The switching point can be up to 6 m away from the process fitting. VEGASWING 63 is the version with extension tube. VEGASWING 61 is mounted directly at the switching point ![]() Vibrating level switches are used as overfill protection or empty alarm. If the vibrating probe comes into contact with the medium, the oscillation rate changes and the vibrating level switch outputs a switching command. The basis of point level detection with vibrating level switches is a tuning fork, i.e.
