Walk Through Metal detector Circuit digaram

[ivconic]

This is how most walk-throughs are designed... multiple TX coils on one side, and multiple RX coils on the other. They create detection zones.

I own a Garrett walk-through, always intended to take it apart and show how the coils are set up, but never have. It's that round tuit thingy...

Can you draw a sketch of coils configurations. At least proper inductances of coil...anything?
I will prepare photo of my unit. Possibly you have same...

walk trough metal detector

sorry for uploading problem, here is shematic.

Sir im ramakrishna. we are very much interested in ur project. We just want to try the same one in our college. So please give me some assistance, on this project.

walk through metal detector

sir,
im ramakrishna. We are doing a project in my college on walk through metal detector, anybody please assist me how to go ahead

What do you think about Delta Pulse and SNIFFER XR-71 ?

[ram.goberu]

sir please give me the details of the components or clear circuit diagram because i dont have enough time for my project so please help me sir

Try using the Hammerhead detector. It can be adapted for use as a walk-through detector.

thank's sir, for giving your valuable suggestion.

i've opened the garret walktrough metal detector (at 2004)..
picture attached (receiver coil)


and the pulse at the tx coil.

You cannot attach any files until you have made at least one post.
Please try again.

Qiaozhi, as far as I am in course a walk-through detector has a system of coils. so there are zones of sens - low, middle and top zones. every zone can be tuned by metal samples, all these samples are marked and everyone has determinated mass you can tune every zone individually.

here, re-attach..


i'll attach other pictures soon

walk-through MD

Hi every one, I am a student of electrical engineering and am doing walk-through metal detector as my final year project, but unfortunately for me, resourses on walk through are scarce on the internet.. Pls I wud lyk someone to give me hints and best approaches on the design and construction of the walk through metal detector.. I will be very glad to get this info.. I know ve got brainies in here.. Thnx a lot guys, my email addy is [email protected]
