Claim 6:
7. 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 the annular shoulder zone, in a first zone of the cylindrical surface of said annular groove being applied a first said strain gauge sensor, having a grid structure with the long branches oriented parallelly to a longitudinal axis of said tubular element, and a second said strain gauge sensor, having a grid structure with the long branches oriented orthogonally with respect to said longitudinal axis, in a second zone of the cylindrical surface of said annular groove, diametrically opposed to said first zone, one third strain gauge sensor and one fourth strain gauge sensor being applied, each oriented as said first strain gauge sensor and said second strain gauge sensor respectively, said first, second, third and fourth strain gauge sensors being connected for defining a full-bridge Wheatstone circuit.
