Each series includes several models, with a number of measurement ranges and output options. A rotary variable differential transformer (RVDT) is a type of electrical transformer used for measuring angular displacement.The transformer has a rotor which can be turned by an external force. The LVDT can be used for displacement measurement ranging from fraction of mm to few cm. APPARATUS REQUIRED: - LVDT kit, multimeter, connecting wires. Linear variable displacement transformer (LVDT) If the core is positioned in the central position, with respect to both the secondary windings, the voltage induced in each of the secondary windings is equal and opposite in direction; thereby the net output voltage from them is zero. Robust construction makes it ideal for both industrial & commercial use. For example in pressure measurement when Bourdon tube acts as primary transducers, it helps to convert pressure into linear displacement. Transducers Direct manufactures an assortment of linear transducers for hydraulic applications, injection molding machines and other positioning applications. Die Primärwindungen erzeugen ein Wechselfeld, worauf sich ein Signal in den Sekundärspulen induziert, dessen Stärke von der Position des Kerns abhängt. Linear Variable Displacement Transducers (LVDT) are plunger-actuated linear potentiometers that measure dynamic displacement. Linear Variable Displacement Transducers (LVDT) are High Accuracy & contact-less. LVDT (Linear Variable Differential Transformer), is an absolute position/displacement transducer that will convert a position or linear displacement from a mechanical reference (zero, or null position) into a proportional electrical signal containing phase (for direction) and amplitude (for distance) information. Actuating mechanisms used primarily for automatic control systems or as mechanical motion sensors in measurement technologies. Now let me explain about the LVDT with its Principle of Operation and I will explain how it is constructed for its well known operation and you can understand the working of LVDT. Notice that when the liquid level changes through the capacitor, the dielectric medium is changed and hence the capacitance will change. They make an accurate position measurement of the movement of the armature (the sliding part) relative to the body of the displacement transducer. 2)As Primary and Secondary Transducers “Primary Transducer”- Bourdon Tube “Secondary Transducer” - Linear Variable Differential Transducer(L.V.D.T) 3)As Passive and Active Transducers 4)As Analog and Digital Transducers, and, 5)As Transducers and Inverse Transducers 5 6.
