![]() It can meet the measurement needs of all different places. The scientific developments include the deposition of polymer, monolayer and antibody coatings, which are applied to the active surface of the sensors. Variety of types: liquid level sensors have various structural designs such as input type, straight rod type, flange type, thread type, inductive type, screw-in type, and float type. The Tuning Fork Sensors are based on the principle of dual tuning forks, which vibrate at low frequencies. ![]() Accurate measurement: The built-in high-quality sensor has high sensitivity, fast response, and accurately reflects the subtle changes of the flowing or static liquid level, and the measurement accuracy is high.ĩ. Strong function: It can be directly connected to the digital display meter to display the value in real-time, or it can be connected to a variety of controllers and set the upper and lower limits to control the water volume in the container.Ĩ. Long service life: Generally, the liquid level sensor can be used for 4-5 years in a normal environment, and it can also be used for 2-3 years in a harsh environment.ħ. When the level switch is used as a high-level point alarm, the liquid rises in the vessel (tank) or pipe making contact with the fork and causing the output state to switch i.e. Wide range of measuring medium: High-precision measurement can be carried out from the water, oil to paste with high viscosity, and wide-range temperature compensation is not affected by the foaming, deposition, and electrical characteristics of the measured medium.Ħ. Building an electronic water level gauge on the river bank can be used for tide monitoring.ĥ. 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. ![]() Wide range of applications: suitable for liquid level measurement of high temperature and high pressure, strong corrosion, high pollution, and other media. Ranges are optional: you can measure the water level in the range of 1-200 meters, and other measurement ranges can also be customized.Ĥ. Convenient installation: When using, first connect one end of the wire correctly, and then put the other end of the water level probe into the solution to be measured.ģ. The operation is simple and convenient.Ģ. Models are easy to use and applications include mining, chemical processing, and food & beverage. Cost effective models are an ideal choice for level control of powders and fine grained solids. With the second line of defense highest degree of safety and availability of the device can be guaranteed. Tuning Fork level switches are sensors with an electrical contact output at a specific level. Simple structure: There are no movable or elastic elements, so the reliability is extremely high, and there is no need for regular maintenance during use. The tuning fork level switch is widely used, mainly for powders and small particles with a wide density range, such as the detection of the dust inlet and. Liquiphant FTL51 is a point level switch with extension tube for use in hazardous areas with all international certificates. Switch Output: SPST Selectable NO or NC states Changes to the oscillationfrequency are continuously monitored by electronics as it varies depending on the liquid medium in which the forks are immersed.The denser the liquid, the lower the oscillation frequency. Factory calibration ensures accuracy over a wide range of liquids, including lubricating oils and hydraulic fluids. Measurement principles Using the principle of a tuning fork, a piezo-electric crystal oscillates the forks at their natural frequency. ![]() The tuning fork sensor is often used in conditions where there may be frequent composition changes in the liquid. VFL Series Vibration Fork Liquid Level Switch. Sensitivity adjustment is available for different densities of media. High/low failure safe mode, safe and reliable. wwwatoationdiectco Level Sensors tULS-49 1-80 o the atet ice eae chec toationiectco. No frequent calibration required, easy-to-use, sturdy and durable design. As the tuning fork is progressively covered by a liquid, a shift in frequency occurs which activates the relay output. The ProSense VFL Series of Vibration Fork Level Switches is designed using tuning fork technology for reliable liquid point level detection for monitoring, alarming, and control applications. Description The LTU-2000 Series Tuning Fork Sensors are point level switches that are designed to detect low or high levels of liquids. The LTU-101A-R consists of a sensor with dual tuning forks which are vibrated at a high frequency.
