Description

I

The invention relates to the field of measurement technology and can be used in sensors for measuring the force, pressure, acceleration ti of other energy parameters.

A known strain gauge transducer containing an elastic element In the form of a ring and tensor resistors connected in an equal-shoulder bridge, with cantilever racks made integral with the ring, with insulators, which are wound to tensions, are located at mutually perpendicular planes at the ends of the elastic element. - tori I.

A disadvantage of the known strain gauge transducer is the non-linearity of the calibration characteristic due to the inequality of the sensitivity of the annular elastic element to movement in the vertical and horizontal directions.

The closest in technical essence to the invention of Ya5 is the tensor

A transistor transducer containing an elastic element in the form of a ring of rectangular cross section with rigid sections along the vertical and horizontal axes and mounted tensor resistances controlled at the ends of the rigid sections of the elastic element 2}.

The disadvantages of the known strain gauge transducer are the insufficient conversion accuracy.

The purpose of the invention is to improve the accuracy of the conversion.

This is achieved due to the fact that in the proposed transformation, the barely rigid sections of the elastic element are made of different sizes in width, the width of the vertical rigid sections being related to the width by the horizontal ratio

"G, 4,, 8Cho where the angle characterizing the width

horizontal hard sections;
