FIELD: oil and gas industry.
SUBSTANCE: inventions refer to the control means of the well sinking process parametres. The device includes a body and an electronic module consisting of a power supply element and the electronic unit provided on the board and including the following electronic components: the point whereat executive programme is programmed, with built-in temperature sensor and calendar time timer, a measuring element, an energy-independent memory chip and data I/O port the input/output whereof is connected to the point where executive programme is programmed. At that, the above electronic components are connected to each other by means of input/output system. As a measuring element, electronic unit consists of at least two gyros located on one and the same board; at that, direction of sensitivity axes at least of two of them differs one from the other. In addition, the device includes a hollow case installed coaxially inside the body and cut into two portions; at that, direction of the cut is made at an acute angle of more than 0° up to less than 90° relative to the case longitudinal axis. At that, electronic unit is installed inside the above case actually along the cut with displacement from the case longitudinal axis; as the point where executive programme is programmed, the electronic unit includes a microcontroller wherein executive programme is programmed, with built-in ATsP analog-to-digital converter, temperature sensor and calendar time timer. Besides electronic unit consists of voltage converter of the measuring element and at least of two buffer amplifying elements.
EFFECT: increasing accuracy and reliability of the downhole motor operating time and rpm measurement.
