RDP Electronics has announced that its range of LVDTs is ideally suited to high duty cycle applications that call for continuous or repetitive measurement.

Process industries, production environments and destructive testing applications need reliable, repeatable results often involving continual feedback with very high cycle lives.

RDP said it has a selection of LVDTs embracing a range of displacements, as well as miniature versions and types developed for special applications.

Used in environments subject to vibration, LVDTs are not subject to the problems associated with potentiometers, for example.

With vibration present, it is not uncommon for small sections of potentiometer wipers to fail prematurely.

There are no such problems for LVDTs.

The spring-return versions can be subject to thousands of cycles.

Captive LVDT versions are said to be good for millions of cycles and, if correctly installed, unguided LVDTs will perform indefinitely.

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).
