As discussed earlier for door frame metal detector, our coil is of size 7ft x 2ft in rectangular shape (4 turns).
How to calculate Rp of LC circuit (using above coil specification) so that Rp_max and Rp_min can be calculated?
We don't have any impedance Analyzer with use. And how to handle this calculation if the no. of devices would be more as a production point of view? As each piece may vary with inductance of coil. Secondly, for this type of coil which type of capacitor you would prefer: SMD or Thru-hole?
Thanks in Advance.
