Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-3.

Example (b): a portable modularized steel rule electric logging instrument is shown in figures 1 to 3 and comprises a cable coiling block 1, a steel rule cable 9 and a probe, wherein one end of the steel rule cable 9 is wound on the cable coiling block 1, and the other end of the steel rule cable 9 is connected with the probe; the steel rule cable 9 combines together for steel rule and wire, and wire and steel rule unite two into one through technology, can prevent the corrosion of steel rule, and the simplified operation process guarantees to measure and reads numerical value convenient more accurate.

The probe comprises a probe shell 4 and a heavy hammer 8, and the top of the probe shell 4 is connected with a steel ruler cable 9; the top and the bottom of the weight 8 are respectively positioned inside the probe shell 4 and right below the probe shell 4, a linear bearing 6 is adopted for sliding between the weight 8 and the probe shell 4, and the top of the weight 8 is provided with a magnet 5;

a passive magnetic switch sensor 3 is integrated in the probe shell 4, and the passive magnetic switch sensor 3 is positioned right above the heavy hammer 8;
