Miniature LVDT Displacement Transducers
RDP's D5/D6 and GT series displacement transducers are ideal for positioning and gauging applications where space is restricted and micron accuracy is required. Available in unguided, spring-extended, and air-actuated mechanical configurations with ranges starting at 0.020 inches. The reliability, small size, and high performance of these units offer excellent solutions for both end user and OEM applications.

The D5/D6 series can be customised to meet a variety of mechanical and environmental conditions thus making them suitable for a wide variety of applications. Now available with ranges up to 6 inches.

The GT series gauging transducer employs precision linear bearings to optimise the LVDTs measurement precision and repeatability.

Using the well-proven linear variable differential transformer (LVDT) principle delivering infinite resolution with absolute measurement, these units provide accurate information over their full linear range starting at 1.0 mm (0.040 inches). The design is robust and reliable and thanks to the LVDT principle where there is no electrical contact across the transducer positioning element the units enjoy a long and trouble-free life. Manufactured from stainless steel, the D5/D6 and GT series family of miniature small diameter displacement transducers  used in conjunction with the RDP range of signal conditioning offer excellent solutions for a wide range of measurement applications.

In addition to these series we have standard models from .020 to 37 inches with a variety of outputs and mechanical configurations.

RDP Electrosense
RDP is a designer and manufacturer and distributor of LVDT displacement transducers, amplifiers, load cells and pressure sensors for use in a wide range of applications. We are privately owned by the two directors who started the company in 1966. Our extensive range LVDT displacement sensors and amplifiers are manufactured by us at our UK head office and factory. RDP was one of the first manufacturers of LVDT displacement transducers and the first to build the LVDT signal conditioning amplifier into the sensor.
