LVDT displacement sensor

SDVG20 DC Separate Core LVDT Displacement Sensor

The linear variable differential transformer (LVDT) has been widely used in applications such as power turbines, hydraulics, automation, aircraft,satellites, nuclear reactors, and many others.These transducers have low hysteresis and excellent repeatability. DC-operated LVDTs are rugged hermetically sealed sensors, stainless steel 304 housing.They are designed for environments containing moisture,dirt,etc.They are designed to operate in conjunction with computer-based data processors(standard) or PLCs(option).

  • Model: SDVG20

Introduction:

The linear variable differential transformer (LVDT) is a position transducer that is noncontact, absolute reading, and has essentially infinite resolution. It comprises three or more coils within which a magnetically permeable core moves to provide variable coupling between the primary coil and the secondary coils (usually two).


The LVDT is a popular choice for high-reliability military applications.They are often used as the position feedback sensor in the actuator for control surfaces in airplanes. LVDT gauge heads are used successfully throughout industry on the production floor as well as in quality assurance.An array of LVDT gauge heads can be assembled to a template of an automobile door, for example. Samples are taken from the production line and placed against the template. Deviations from the standard profile are measured and used to determine if the tool making the door panels needs adjustment or reworking to keep the finished parts within the allowed tolerances. Incoming inspection tools use LVDTs to measure critical dimensions and read them into a computer that compares the data against the accepted tolerances.
