AXIAL LOAD Russian patent published in 2007 - IPC G01V3/00 

FIELD: the invention refers to geophysical technique of exploration of wells.

SUBSTANCE: it is designed for controlling of compulsory movement of well devices along the trunk of horizontal plots of wells particularly with using coltubing installations. The sensor of an axial load has a body in which there are a running rod, a power calibrated spring, a sensor of axial transfer of the running rod representing inductive differential transformer in the E-shaped coil located inside the running rod movable relatively to the armature rigidly connected with the body. The running rod is firmly connected with the module of transformational scheme and with the intermodule connector in the low part and in the upper part - movably with the indicative head designed for joining the body with the coltubing tube.

EFFECT: increases reliability of the construction of the arrangement, increases accuracy of measuring loads.
