RDP transducers are suitable for measuring movements in the structure of bridges caused by the weight of traffic, environmental conditions and various other factors.

According to the company, high traffic loads and corrosion can lead to increased strain in bridge components, such as suspension cable fixing points.

Therefore, it is important for engineers to understand movements and loads imposed on the structure in order to predict potential problems and to maximise the safe working life of the bridge.

Key benefits

  • RDP’s transducers are said to be able to monitor movements in coastal regions thanks to their high water ingress protection rating.
  • Transducers can be supplied that are moisture resistant or fully welded for submersible applications.
  • Thanks to their stainless-steel construction, the transducers are suitable for operation in marine environments and are able to resist the corrosive effects that occur as a result of winter road treatments for ice. 
  • The LVDT monitoring approach is claimed to be relatively inexpensive, particularly when several points on a bridge need to be monitored, calling for long cable runs.
  • By using a 4–20mA two-wire loop, the wiring installation cost can be reduced.

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).
