RDP Electronic’s LVDTs are suitable for providing feedback for control valve positions, and for use in proportional control valve applications and situations where hydraulic pressure needs to be steadily built up.

The LVDTs allow direction and amount of fluid flow, and pressure within a system to be managed through proportional valve control. This is suitable for situations where the speed of a system needs to be strictly controlled and where ramping up and down is needed to avoid sudden starts or stops.

The products can also be immersed in the non-corrosive and non-degrading oils that are often used in hydraulic systems.

Additionally, the LVDTs have a high-speed response and can function over a wide range of temperatures.

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).
