2. Structure and principle of operation
As shown in the picture, the pointer of the load cell driven by the high subsection
driven step-motor is driving the rotor to go round and round through the hairspring and
rotating axis. If the rotor is not resisted by the liquid, the pointer of the hairspring load
cell is in the same position with the pointer of the load cell for the step-motor. On
contrary, if the rotor is being resisted by viscous liquid, the hairspring produces the
wresting square and repel and balance with the viscous resistance for reaching the
balance at large. At this moment, by transmitting the output signal by the
photoelectrical load cell to 16 bit micro processor for data processing, the viscous
value (mPa·s) will be displayed on back-lit LCD screen.
