Claim 7:
8. High-pressure mixing device according to claim 5, wherein on an outer cylindrical surface of said tubular element an annular groove is obtained extending circularly at said annular shoulder zone, in which cylindrical surface a first said strain gauge sensor is applied, having a grid structure with long branches oriented parallelly to a longitudinal axis of said tubular element, and on a surface of said shoulder zone orthogonal to said longitudinal axis a recess seat is obtained on whose plane surface, orthogonal to said longitudinal axis, a second said strain gauge sensor is applied, that is sensitive only to thermal deformations, regardless of the direction of orientation of its grid structure, said first strain gauge sensor and said second strain gauge sensor being connected for defining a half-bridge Wheatstone circuit that includes two external calibrated resistances.
