For projects calling for hundreds of strain-gauge transducer channels, RDP claims that analogue signal conditioning can be more resilient to electrical-supply fluctuations than digital devices.

Analogue also offers the benefit of long cable runs without the need for further amplification.

In circumstances where amplifier replacement becomes necessary, thanks to the capability to enable standardised calibration from matched transducers, units can be swapped out with minimal effort.

RDP offers a choice of signal-conditioning amplifiers, including the Modular 600 multi-channel signal-conditioning system.

The Mod 600 is a fully featured microprocessor instrumentation unit that incorporates configurable analogue outputs and is based on a modular design concept to provide complete flexibility and expandability.

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).
