RDP Electronics has developed versions of miniature LVDTs that can operate submersed in non-corrosive, non-conductive oil at pressures up to 2,000 bar.

Typical applications that require operation in oil include mounting the transducer within a pressurised valve where the device may be subjected to high levels of air pressure or vacuum.

Based on RDP’s D5, D6 and ACT transducers, the modified versions maintain the same miniature dimensions and do not compromise the accuracy, infinite resolution and life-cycle characteristics of the standard models.

The design modifications allow a high pressure rating by ensuring a free fluid flow around the transducer, although some applications may be restricted to a maximum temperature of 30C.

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).
