RDP Electronics has revealed a simple-to-install and economical system for torque measurement, using off-the-shelf transducers where applications do not require high dynamic response.

Although RDP offers a comprehensive range of torque transducers, these require good alignment and often a break in the shaft as well.

Frequently, it is possible to mount a motor or a braking device with bearings, and restrain it using the torque armature.

A load cell can then be used to restrain the torque arm and the end distance from the load cell mounting and point of rotation, enabling torque to be calculated.

Because RDP stocks a range of affordably priced load cells, this approach to torque measurement also has the advantage of availability and low cost.

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).
