Abstract:
     The disclosed intelligent storable industrial metal detector comprises: a signal emission part controlled by a MCU to oscillate and generate stable high-frequency signal, a band-pass filter line to obtain the high-frequency reference signal, a power amplification circuit to send information for antenna, a detection field with a stable ultrasonic magnetic field, a receiving loop to receive symmetrical signal and difference amplify to obtain the current signal contained magnetic field information, a low-pass filter network to change the detecting output signal into one varied as metal object effect, and a A/D sampling circuit to send the circuit to the MCU. This invention has well detection effect.
