Product Details Supplier Info More products

RDP Electronics is offering specially ruggedised, sealed sensors for use in manipulating radioactive substances. Typical applications include robotic devices or handling equipment for radioactive waste in cooling ponds.

According to the company, these applications require waterproof sensors with high radiation resistance.

RDP’s engineering support team is available to discuss and advise on requirements for applications where standard products are not suitable.

Key information

  • RDP develops special designs where all components are welded together to ensure that there is no possibility of any parts breaking loose from the transducer.
  • Components such as armature and push rods are welded together and all external case components are welded to the case so they cannot become detached over time.
  • In these applications, it is also usual practice to use external signal conditioning amplifiers for the transducers.
  • Transducers are usually calibrated for use with multiple amplifiers, so that in the event of an electronics failure the amplifiers can be replaced without requiring to access the transducer itself.

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).
