RDP Electronics is offering space-saving dual-bridge load cells that are suitable for critical structural testing and monitoring in the aeronautics and automotive industries, for example.

According to the company, a load cell with two separate and independent sets of strain gauges delivers sensor redundancy within a single unit.

This allows two sets of signal conditioning electronics to be deployed so that in the event of a failure of one, the second signal conditioning set maintains system integrity until the fault can be rectified.

In addition, under normal operating conditions, the two outputs can be compared to provide greater certainty of data integrity, enabling the rapid diagnosis of any faults.

RDP’s dual-bridge load cells are said to be cost effective thanks to the dual outputs.

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).
