STRAIN GAUGE AND SYSTEM FOR DETERMINING SPATIAL POSITION OF SUCH SENSORS Russian patent published in 2016 - IPC G01B7/16 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, particularly to design of a strain gauge, a system for determining its spatial position, a method of determining its spatial position and measuring system using strain gauge. Strain gauge (1) comprises substrate (2) for installation of element (3), subjected to reversible extension under action of force applied during change in resistance of said element (3), and capable of elongation along measurement axis of strain gauge.

EFFECT: according to present invention, strain gauge (1) comprises at least one contrast object (5, 6), configured to reflect incident light beam and located on strain gauge (1) in preset position relative to measurement axis (4) of strain gauge (1) and relative to centre of strain gauge (1), which enables to determine centre and measurement axis (4) of strain gauge (1) by detection of position of said at least one contrast object (5, 6), which is a light-reflecting object.
