Abstract: The present invention discloses a non-contact AC/DC sensing probe and a sensing method and application thereof. The non-contact AC/DC sensing probe adopts a Hall sensing module, breaks through the limitation that a traditional induction coil can sense only an AC current, and can directly perform AC/DC sensing on a single wire or a cable composed of two or more wires, so as to allow the target wire to generate an electromagnetic signal to be collected by the Hall sensing module, and sensing of electrical parameters, including a current, a voltage, a frequency, a duty cycle, a phase, a harmonic, a frequency-conversion signal, etc. is realized without peeling and cable branching, so that the non-contact AC/DC current sensing probe is simple and convenient to operate, can be applied to measuring instruments such as a test pen, a multimeter and a clamp meter, and has a wide range of applications.

Abstract: The present invention discloses a non-contact alternating current sensing probe and a sensing method and application thereof. Alternating current measurement can be directly performed on a single wire or a cable composed of two or more wires. During detection, the detection port is adjusted to a better measurement position of a target wire through position adjustment, so that an electromagnetic signal generated by the target wire passes through the detection port and enters the shielding space to be collected by the induction coil, sensing of alternating current-related electrical parameters, including a current, a voltage, a frequency, a duty cycle, a phase, a harmonic, a frequency-conversion signal, etc. is realized, and the probe can work for a long time, cannot lead to the problem of inaccuracy caused by heat, can be applied to measuring instruments such as a test pen, a multimeter and a clamp meter, and has large application prospects.
