Think of driving two elliptical coils in range of 50-200kHz with high VAR at resonance and measure the difference in current for series or voltage parallel tuned after balancing each to a null difference. Stepup auto transformers are allowed . The phase shift and amplitude difference is essentially the differential impedance of each coil as it
Hello everybody, I can't find anything about mcCheck sx 3300profi metal detector, except the price of the device. I would appreciate any kind of help for this issue. The problem is that the detector's coil has been broken from the body and the person who tried to attach the coil, somehow replaced the wires from the coil probe. By (...)
Hi, I am designing a walk-through metal detector using two separate coils namely transmit and the receive coil. It is a single zone metal detector. I couldn't figure out how the coil arrangements would be and how would the coils be inductively balanced. Would you please explain me? Thanks.
Hi, I have seen a circuit as attached for metal detector. Can anyone please explain me what is basic functionality of the opamp in that circuit arrangement. Pin2 is going to the input (-)of another opamp. Please explain me the functionality of this type of circuit. Thanks.
You can use e.g. an AM radio and a suitable oscillator in a metal detector, but if the searched object is located in a wet soil, it will not work. Most metal detectors use lower frequencies, 10-100 kHz, to penetrate wet sand and soil.
Hello searching the web I found this schematic of a metal detector Final and the picture I was wondering how good this schematic is, this is quite complex regarding simple metal detectors I have found on the web. it also hase a single coil so construction of
Hello. I am looking for a PI metal detector circuit schematic using the atmega8 micrcontroller. Could anyone help me with this?
Here is the Magnum metal detector: By today's standards it may look a little bit old-fashion, but it is well documented and easy to build .. IanP :D
You have two options: simple unit or one that works .. I prefer the latter .. So, here is detailed description of MAGNUM metal detector .. Funny thing about it is that you can use a couple of plastic plates from you kitchen as bases to construct the coils .. Rgds, IanP :D
Guys could anyone have a related subject sites or links or anything concerning a walk through metal detaector, specially its schematic diagram could u plz pass it to me. This is not the metal detector that is used to detect metal or mine in the ground, i want the on that is used in the airport, and the (...)
hi i'm giving you metal detector schematic and pcb. its realy good. regards.
I am looking for good and simple schematic of sensitive metal-detector on large width (approx. 1,5-2 meter). Please, help! Please search forum first or use google. and I think both elektor and EPE mag have published such projects. Alos try to post in right topic
Oh well, the BFO type metal detectors are on the bottom of the food chain ;) Here is a nice colection of info about the metal detectors/magnetometers.
Hi Send a Private message to Simbox. He loves metal detectors, and I think he's the best person who can help you. Regards No Fear
I have stored 2 kind of metal detector based on microcontroller. I build both and i am sur it is good. Have a look at filemanager: Neron/metal_detector. If someone have other schematics i am interrest.
