Experimental and theoretical curves of the Toroid FCDT

A project log for A new high accuracy tilt sensor

This project aims to build a tilt sensor that is cheap, very accurate and has a wide measuring range (up to 360 degrees).

Previous post: Theoretical background of the Toroid FCDT (

Now that we know from the previous post that how to calculate Vsec1, and Vsec2, we can move on to calculate Uout of the sensor with respect to the tilt, and compare our results with the experimental data.

In this post I'm going to compare the theoretical and experimental curves of our Toroid FCDT.

The output voltage of the toroidal sensor is given in a form of The M cell constant was determined using the known dimensions of the cell, and the extreme values of Uout,

The theoretical and the experimental curves of the sensor can be seen on the graph below:
