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.
