Transducer specialist RDP Electronics offers a comprehensive range of LVDTs, including versions that can be used to monitor the movement of cracks in structures.

Measuring the changes in the width of cracks that occur in civil buildings can be accurately determined by the use of linear variable displacement transducers (LVDTs).

This diagnostic technique can provide data to help understand the cause and then action appropriate remedial work where needed.

RDP offers a range of LVDTs including waterproof options for use in external applications and harsh environments.

Using analogue versions with a 4-20mA facility permits the use of long cable runs, which can prove a useful capability where location of monitoring equipment is remote from the crack location.

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).
