LDC1000EVM, Proximity Data

Amaia Azpitarte

Hi all,

How can I calculate the distance (mm) of the object to the coil? What is the relationship between the distance (mm) and the value of "Proximity data"?

I will be gratefull for any help you can provide.

Hi,

That`s relate to your coil and target, also with Rp range configuration, so you need to set up your system and get lots data, it`s not linear, arithmetic will be needed. One of our team member is working on 2 point calibration apps note and will be published soon.

Regards, Sunny.

Hello Sunny,

One more question Related to the topic is : In order to obtain the linear displacement in mm, can the proximity data obtained in the GUI be considered ? i.e., can the proximity data be plotted against the distance in mm (or microns), in order to obtain the linear/non-linear displacement ?

Hi,

We didn`t have that function yet, because differernt coil will need different arithmetic.

Hello Sunny,

Yes, I agree that the arithmetic involved is different for different coils, however I wanted to know whether the procedure involved is the same for any coil.

With Regards,

Hi,

Sorry, we are working on that now, so you may need to wait some time before it release.
