Product Details Supplier Info More products

RDP Electronics is offering a range of linear variable differential transformers (LVDTs) for use in a variety of industries for testing or routine displacement measurement applications.

Thanks to their non-contact measurement principle, the LVDTs – offered in a choice of sizes and versions – are claimed to offer a long cycle life.

For customers unable to find a suitable off-the-shelf model, the company can provide customised solutions tailored to a variety of applications.

LVDTs are able to operate in high-temperature environments, under pressure, subjected to radiation, in wet locations, at the bottom of the ocean or subjected to corrosive fluids.

They are designed to play an important role in aerospace, automotive, civil engineering, oil exploration and process applications.

The displacement output can be analogue or digital, and the LVDTs can be supplied with suitable equipment to display measurement readings or to feed data using a 4-20mA signal into control devices such as programmable logic controllers.

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).
