![]() These sensors can be used to detect the presence or absence of granular, solid, or powder materials with densities as low as 2 lbs./cu.ft. Fig. Tuning Fork Level Sensors The Pulse Point is a tuning fork point level sensor that may be used to detect high and low levels in bins, tanks, and silos. It forwards the signal in the form of pulse frequency modulation continuously to computer unit for density calculation. After the recent Intrinsic Safety Approval we are now announcing the launch of AS-Interface output. Its back to back upgrades to our Elixir Series (Vibrating fork for liquids) of instrument. The vibration of the tuning fork is sensed by a pickup piezoelectric element. Sapcons vibrating fork level sensor series is now accessible with a simplified network protocol called the 'AS-Interface'. In most the most common embodiment of the vibrating fork type level switch working principle the harmonic vibration of tuning fork sensing element is established using Piezoelectricity. The tuning fork is excited by piezoelectric method. See More Items from this Family (17) Added to Your Shopping Cart. The tuning fork sensing element is placed into vibration at its natural resonant frequency by establishing motion in the sensing element or fork. The LTU-2000 Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids and is based on the vibrating tuning fork principle. The vibrating fork type level switch working principle uses a tuning fork shaped sensing element with two tines inserted into the bin or tank where the target media will be present. A tuning fork causes by internal crystal resonance, when the tuning fork is immersed by liquid or solid, the vibration frequency changes, and detected by the. 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 the presence of the target media. At present, the lowest material density that can be. It is a solid level switch specially used for measuring powder and fine particles. tuning fork type level switches) reliable, cost effective and very popular for use in detecting the presence or absence of liquids and bulk solid materials. The vibrating fork body (also called fork wings) of the tuning fork level switch is longer and wider, with a typical size of 150mm long, 22mm wide and 4mm thick. Tuning fork switches utilize vibration measurement to detect levels and are ideal for powders and fine-grained solids. This makes vibrating fork type level switches (a.k.a. Solid materials: fly ash, cement, stone powder, plastic particles, salt, sugar, etc.The vibrating fork type level switch working principle is simple and effective. The tuning fork is ideal for use either in adhesive and abrasive products as well as in. This component constantly produces high-frequency vibrations. The level switch detects reliably and robust the min. Vibrating level sensors are also known as tuning fork level sensors because they typically feature a fork or rod. The VEGAWAVE 61 is a level switch for universal use in powders and fine-grained bulk solids. Measuring medium: dry particles, powdery materials and various liquids, slurries, etc. The tuning fork design is very robust and unaffected by buildup. 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. 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. For point level detection in liquids a sensor in form of a tuning fork is excited at its resonant frequency. It is mainly used in metallurgy, building materials, chemical industry, light industry, grain and other industries. 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. ![]() 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. It mainly uses the resonance principle of tuning fork to measure the level state. Tuning fork level switch is a kind of level switch. Vibrating level switches and vibrating rod level switches are based on the same principle: a rod or a pair of blades are set in vibration at their resonance. 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. A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs ( tines) formed from a U-shaped bar of elastic metal (usually steel ). ![]()
