Linear variable displacement transducers (LVDTs) from RDP Electronics are inherently robust and durable enough to meet the rigours of testing in situations generating vibration or shock.

Such test situations are numerous, but typical applications include vehicle testing, recoil testing, switchgear testing and use on rolling mills and steel-production machines, which often involve high levels of shock and vibration.

Due to the rugged LVDT technology they have a high cycle life, high accuracy and repeatability with the added advantage of being an absolute device with infinite resolution.

Because the sliding core of an LVDT does not touch the inside of the tube in which it is housed, it can move without friction, making it highly reliable device, while the absence of any sliding or rotating contacts allows the device to be totally sealed.

Typically the housing is of stainless steel, providing high levels of protection against the operational environment.

RDP offers ranges of LVDTs for many types of accurate displacement measurement.

RDP Electronics – experts in measurement solutions

Measurement experts RDP Electronics Ltd have 45 years experience in developing transducers for a diverse range of applications in research, prototype testing, industrial plant and machinery, or embodied in products. Examples are numerous, spanning industries that include aerospace, automotive, structural engineering and power generation. The company is responsible for the development and manufacture of a comprehensive programmme of transducer products and associated electronics to recognised international standards for accurate and reliable measurement of displacement, load, pressure and torque. Often the best solutions have a simple elegance that is possible thanks in part to the quality and high reliability of the transducers they supply. Because of their knowledge and expertise RDP’s skilled engineering team is frequently invited to propose solutions to measurement challenges.

RDP Design, manufacture and market a wide range of LVDT and other displacement transducers. LVDT Displacement transducers accurately measure position and displacement. The strength of the LVDT is in its principle of operation. As LVDT sensors are inductive, there is no electrical connection across the sensing element ensuring clean data and a long life.

The LVDT operation principle lends itself to use in extreme environments. LVDTs can be made to work submerged in sea water, in temperatures of 600°C (1100°F) in high nuclear ratiation and at pressures of up to 2000bar (30,000psi).
