The word LVDT stands for Linear Variable Differential Transformer, an electromechanical transducer that can linearly convert position of an object to which it is mechanically attached into DC voltage. LVDT: Linear Voltage Differential Transducer. As LVDT is an AC controlled device, so there is no any electronics component inside it. Looking for online definition of LVDT or what LVDT stands for? Follow Us on LinkedIn. This association of a signal value to a position occurs through electromagnetic coupling of an AC excitation signal on the primary winding to the core and back to the secondary windings. If you are visiting our non-English version and want to see the English version of Linear Variable Differential Transducer, please scroll down to the bottom and you will see the meaning of Linear Variable Differential Transducer in English language. It is a mutual capacitive transducer. info@transtekinc.com, Like Us on Facebook The linear variable differential transformer has three solenoidal coils placed end-to-end around a tube.

Induktive Sensoren (LVDT) Als Spezialist für Weg-, Abstands- und Positionsmesstechnik möchten wir, die eddylab GmbH, Ihnen auf dieser Seite die Technologie der induktiven Sensoren (LVDT) näher bringen und die Möglichkeiten und Vorteile unserer Wegaufnehmer erläutern. An LVDT's resolution is essentially infinite as it operates on the principle of magnetic coupling. LVDT is an acronym used for the l inear v ariable d ifferential t ransformer. This sensor device measures linear displacement (or linear position) very accurately. The LVDT stands for Linear variable displacement transformer while the RVDT stands for Rotatory variable displacement transformer. This coil assembly is usually the stationary element of the position sensor. A ferromagnetic core links the electromagnetic field of the primary coil to the secondary coils. LVDTs have a moving core and are naturally frictionless giving them a long life. Differencing the output of these coils will result in a voltage proportional to the relative movement of the core versus the coils. It is the most widely used inductive transducer that covert the linear motion into the electrical signals. What does LVDT stand for in text In sum, LVDT is an acronym or abbreviation word that is defined in simple language. And the RVDT converts the angular displacement into the alternating current. LVDT stands for Linear Variable Differential Transformer, they are a type of non-contacting position sensor and are used to measure linear displacement. When activated with a set AC s… Link/Page Citation. Viele übersetzte Beispielsätze mit "lvdt measurement" – Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen. Ellington, CT 06029, P: 860-872-8351 or 800-828-3964 The moving element of an LVDT, commonly called the core, is a separate cylinder of magnetically permeable material. Layer Wound LVDTs usually consist of a steel coil form. b. Thanks for visiting us! If you don’t find what you are looking for, we can custom design a product to your specifications and requirements. The output across secondary of this transformer is the differential thus it is called so. The core usually connects to the moving part of the system, and can move axially within the LVDT bore. An LVDT is also referred to as a linear displacement transducer, or linear position transducer. This page illustrates how LVDT is used in messaging and chat forums, in addition to social networking software like VK, Instagram, Whatsapp, and Snapchat.
