Claim 10:
11. High-pressure mixing device according to claim 5, wherein said strain gauge sensors are arranged such that deformation components are eliminated due to thermal expansion, and wherein a modulator-amplifier of the variations of the electrical signal coming from a Wheatstone bridge defined with strain gauge resistances is provided, said modulator-amplifier being arranged to modulate and demodulate said electrical signal to reduce its interferences, being further provided a control unit on which the aforesaid electrical signal proportional to the sum of the friction can be stored, scraping and bonding forces exchanged between said tubular element and said cleaning member, said control unit being configured to allow mapping for each movement and to provide a comparison between a normal operating condition of the tubular element and of the cleaning member and an abnormal condition of operation thereof.
