AI Technical Summary
Magnetostrictive pressure gauges are prone to displacement when measuring large liquid surfaces, leading to inaccurate measurements.
The positioning mechanism includes components such as two positioning chucks, locking screws, locking nuts, limit slides, and limit clamps. The locking and limiting structure ensures that the measuring device is in the center position, and the combination of cable counterweights and magnetic floats prevents deviation.
It effectively prevents the magnetostrictive pressure measuring tube from shifting, ensuring measurement accuracy and allowing the magnetic float to move freely outside the waveguide wire, thus avoiding the effects of eccentricity.
