RDP Electronics can provide a range of signal conditioning systems, including panel and Din-mounted options for applications using multiple transducers.

Where there are a number of transducers in close proximity, a more economic and space-efficient solution can usually be achieved by selecting either the RDP Modular 600 or DR7 Din-rail options, rather than using several individual devices.

The Modular 600 is a fully featured microprocessor instrumentation system, which also incorporates configurable analogue outputs.

Its modular design concept, based on the standard Eurocard format, can accept inputs from up to 164 channels in either free standing or rack form.

It can be tailored to measure most engineering parameters including displacement, pressure, load/force, strain, torque and vibration utilising a range of signal conditioning modules suitable for LVDTs, load cells and strain gauges.

The DR7 series comprises fully isolated Din-rail mounted, DC-powered amplifiers designed for simple integration into industrial systems, avoiding potential earth loop noise problems, and are fully compliant with European Directives and regulations for EMC and electrical safety.

The DR7DC strain gauge transducer amplifier and DR7AC LVDT transducer amplifiers can be installed in suitable cabinets along with other similar devices.

To reduce electrical noise, system problems and the risk of accidental damage the DR7 has full isolation between supply and output.

A wide supply voltage tolerance and selectable excitation ensure that the DR7 is compatible with a very wide selection of transducers and applications.

Further information and guidance on specifying signal conditioning amplifiers can be obtained from the RDP engineering support team.

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).
