TL12000

[Carl-NC]

hi for all.I made a TL12000 device, but it does not sense any metal despite the availability of the required frequency and voltage.i need your help .thank you in advance

Without an oscope about all you can do is make sure the power supplies are all correct and that none of the opamp stages are saturated. An oscope is a necessary tool for troubleshooting.

Thank you so much

Finally, the TL12000 device worked, but I faced a problem, which is that the Bu508a heats up and the device's sensitivity is weak.The frequency is set to 150Hz and the coil is 40cm 20 turns.If anyone has a solution to this issue, please let us know and thank you in advance.

Dear Daluka, this is the pcb Mohammed Nasr pcb says, this is the pcb in the video but it is not complete, can you send it back?

How much depth is possible by using this to detect buried metals.?
