FIELD: drilling technologies, in particular, engineering of equipment for measuring frequency of rotation of turbo-drill shaft, or volumetric engine and can be used during driving of horizontal and inclined wells for receiving operative information during drill.
SUBSTANCE: device contains sensitive element, positioned on body, mechanically connected to shaft of face engine, and electronic circuit. Sensitive element is made in form of differential ferro-probe, mounted so that sensitive axis of ferro-probe was perpendicular to rotation axis of face engine shaft, and outputs of measuring winding of ferro-probe were connected to electronic circuit, realizing selection of maximums of amplitude of output EMF of differential ferro-probe and transformation of temporal period between them to number of turns.
EFFECT: simplified construction of sensitive element and decreased dimensions of device.
