How it Works - Micropulse
The transducer comprises a sensor element (shown in blue), a signal converter (at the right of the diagram) and a position magnet.

The signal converter applies an electrical pulse to the sensor element and simultaneously starts a timer.

The magnetic field generated around the sensing element by the electrical pulse interacts with the field of the position magnet and produces a mechanical pulse.

The mechanical pulse travels back down the sensing element where a sensor in the signal converter detects it and stops the timer.

As the speed of the mechanical pulse is constant, the time taken for the pulse to reach the sensor can be used to accurately measure the position of the magnet.

Typically the mechanical pulse travels at 2800m/s and the cycle process is repeated 1000 times per second.

About us
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.

With over 50 years of experience designing and manufacturing LVDTs and other types of linear position transducers we can normally offer a solution from our vast knowledge base to meet your application requirements.

Call us at 1-800-334-5838 to discuss your special needs with one of our application engineers and we will design a custom solution.
