RDP supplies specially manufactured transducers that are designed for used in the space and satellite industry.

The transducers are completely sealed and manufactured from low outgassing materials to standards that have been specified by NASA for applications in space.

This avoids the risk of contaminating other components used on space vehicles — such as optical devices — with expelled gases from transducers.

In addition, the outgassing of vapour escaping from internal adhesives and varnishes is reduced by ‘baking’ the device in order to thoroughly dry out these types of materials.

Modifications to the device during the manufacturing process ensure that there are no sealed cavities in which a pressure differential could cause damage.

Further benefits

  • Each transducer is fully welded to seal residual vapours inside the unit
  • The manufacturing process minimises the risk of damage to the transducer through slow pressure changes

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).
