  • Faraday Sheild Reduce Sensitivity

    Faraday Sheild Reduce Sensitivity is this true. Does this shield reduce the reflected pulse amplitude, can anyone here check this with an oscilloscope and tell without the sheild and with sheild.

    Faraday Shield Reduce Sensitivity

    Sharky, a Faraday Shield (or screen) should not have any effect on the receive coil sensitivity, as the shield only screens against electric / electrostatic fields, not the magnetic fields generated by the transmit coil and detected by the receive coil.
    I understand that one of the main functions of the Faraday Shield is to help reduce ground capacity effects.

      Hi Duncan and others
      I am using a 2 coil Pi, one for TX and one for RX both electrically isolated with optocoupler, I have to imagine the rx coil doesnt reduce the signal level from the target, can anyone measure this with a nce sensitive scope. Is there a better IC other than LM318 with slew rate of 50, and noise figure of < 4nV, can we replace the schematic directly by LM318 removing the uA709 in the project
      Twin Loop Treasure Seeker (Robert & David Crone, ETI LINK http://geotech.thunting.com/cgi-bin/...loop/index.dat), Just look at the compensation and the pin8 connection, can we eplace the schematics uA709 withLM318. whats the noise figure for LM318...

      regards
