FIELD: computer equipment.
SUBSTANCE: invention relates to the calibration of sensors in a well. In particular, the device for in-well calibration of sensor is proposed, comprising a housing, having an axis and a gimbal mechanism located in said housing, wherein the gimbal mechanism comprises at least one sensor. Moreover, the specified gimbal mechanism further comprises an external gimbal, made with the possibility of rotation relative to the body, and internal gimbal, supported to be rotated relative to the external gimbal, the way the sensor has the ability to rotate about three perpendicular axes. Internal and external cardan hangers are relatively rotatable to move the measuring axis of the sensor along the three-dimensional orbit.
EFFECT: technical result is the elimination of limitations in the calibration of temperature drift and other errors in the gauge of logging instruments.
