Other Parts Discussed in Thread: LDCCOILEVM
Hi,
I've already used with success LDC1314 as metal target proximity detector.
My new project is a linear position sensor with long travel: around 30cm
1) Evaluation coils and application notes put a limit at 10cm
Why?Is it possible to reach longer length?
2) In any case I could put coils in "series" to reach the desired detecting lenght.
What about this?
3) I also have some doubts when the metal target covers two closed coils; is the sensor reading correct and linear in this particular position too? Some "crosstalk" bad effects due to parasitic mutual inductance?
Thank you in advance
