With LVDTs, the phase of the output … Due to their function, LVDT displacement transducers are one of the most reliable and robust sensors. The push rod of the transducer is screwed into the piston and moves inside the sensor body when the hydraulic cylinder is actuated. Linear Variable Differential Transformer (LVDT) sensors are inductive type devices that measure linear displacement. The LVDT is designed with long slender coils to make the output voltage essentially linear over displacement up to several inches (several hundred millimetres) long. The Linear Variable Differential Transformer (LVDT) is a type of sensor which converts linear displacement into an variable electrical signal. The LVDT is basically a differential transformer, whose voltage output is proportional to the displacement of the object, hence it is given the name linear variable differential transformer. The new MSC7401 controller is designed to be operated with LVDT and LDR measuring gauges and displacement sensors. A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. Overview: The Rotational Variable Differential Transformer (RVDT) is used to measure rotational angles and operates under the same principles as the LVDT sensor. The strength of the LVDT sensor's principle is that there is no electrical contact across the transducer position sensing element which for the user of the sensor means clean data, infinite resolution and a very long life.
