It is composed of a group of coil windings wound on a soft iron core, two permanent high-temperature resistant magnetic steels, fixings , connecting parts , outer casing, etc.

The tool is equipped with tension sensor, temperature sensor and resistivity sensor, which can measure the tension at the tool location, the temperature and the resistivity of drilling fluid respectively. It communicates with the telemetry GR tools.

It can communicate with the surface system in ADSL mode, with an effective rate of ≥ 800Kbp/s ; it can communicate with 580 tools by Ethernet , with a rate of 10M ; it can measure the natural gamma ray.
