Abstract

A wide-range inductance measuring head is composed of a measuring guide rail and a measuring magnetic circuit in a connecting mode. The measuring guide rail is formed by the fact that a measuring rod is arranged inside a shaft sleeve. A measuring head is arranged at the front end of the measuring rod, a measuring steel ball is embedded at the front end of the measuring head, a holder is arranged on the measuring rod, four rows of stabilized steel balls are evenly arranged between the holder and the measuring rod, the rear portion of the measuring rod is connected with the front end of the holder, and a limiting device is further arranged on the measuring rod. The measuring magnetic circuit is that a magnetic core is arranged inside a magnetic sleeve, a coil framework is sleeved outside the magnetic core, a left magnetic ear and a right magnetic ear are respectively arranged at two ends of the magnetic core, and a left limiting device and a right limiting device are further arranged on the left magnetic ear and the right magnetic ear. A connecting rod is arranged at the right end of the magnetic sleeve, the connecting rod penetrates through the right magnetic ear and is connected with the magnetic core, and a spring device is arranged on the connecting rod.
