RDP Electronics has developed an arrangement using a pair of LVDTs to offer extreme reliability of data signalling for critical applications.

Although LVDTs are known for accuracy and reliability, there are some critical measurement tasks where dual redundancy is specified.

Typical applications are in the nuclear transport and power generation industries where data signalling is used for control purposes.

The operating principle of linear variable differential transformers (LVDTs) requires 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.

RDP manufactures LVDTs to internationally recognised quality standards and offers a comprehensive range for a variety of displacement measurement purposes.

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).
