Magnetic coil calculation

[ksrctpravin]

hi guys i design a flat metal detector for industrial conveyor purposes,i use induction balance principle ,that is single transmitter and dual receiver concept

i use three air core inductance coil in the

can any one help me how the coil winding has to be made so that my sensing distance i can reach is from 10mm to 60mm distance


just tell me how many turns of winding needed in all three coils to achieve the distance and any other parameters if possible

More info is needed.

How large of detection area are you needing here?

What Freq is the Detector running?

Do you have a Schematic of the detector to look at?

inductance calculation

in induction balance of two receiver and single transmitter concept of metal detector ,can u tell me whether coil turns in transmitter coil is equal to receiver coils or greater than receiver coils

You are providing almost no information, so no one is going to be able to help you.

Do a Google search for 'Wheelers Formula'. This will tell you the properties of your coils, and may help your design.
