uDSProbe Working Principal

Introduction

Magnetostriction effect is observed in ferromagnetic material and is defined as ability of a material to change its mechanical properties when subjected to a magnatic field (Jack, 2015). The material either expands or contracts based on various factors, which induces mechanical strain in the material.

This effect has been of great industrial interest for use in sensors, actuators, adaptive, or functional structures, robotics, transducers, and MEMS.

Joule first observed the magnetostriction effect on an iron bar; further experiments performed on Fe-Ni alloys led to the discovery of the Invar effect by Guillaume. Since then, a vast discipline in condensed matter studies has emerged.

Magnetostriction Effect in Level sensor

Magnetostrictive probe works on principle of magnetostriction effect described above.
A magnetostrictive level probe is built by suspending a ferromagnetic metal wire inside a long stainless-steel shaft/pipe.
The electronic components, mounted safely at the top of the stainless-steel pipe, generates an electrical pulse that travels down the wire, at regular intervals. This creates an electric field. The level/density float, containing the ferromagnetic compounds are installed around the shaft (as illustrated in diag). The buoyancy of the float allows it to move freely around the shaft with variable changes in the liquid level. This, in turn results in a magnetic field, created by the magnets inside the float. A micro vibration is produced at the location of float, this vibration is the key to determine the accurate level. Vibrations travels at a known speed, and therefore can be timed to accurately measure the distance by the electronics in the probe housing. Probe can have multiple floats to measure required parameters of multiple liquids. This is achieved by tuning density of float for the liquid. Probe also contains temperature sensors which measure temperature of fuel at different locations. The uDSProbe can also be used to measure the density of the liquid. A density float is fully immersed in the liquid and electronics inside probe is programmed to calculate density in real-time.
uDSProbe uses Digital Signal Processing for all it's computations. Thus produces accurate and reproducible results for level and density.
