One of key factor of measurement is exactly the time interval through two positions point for the accurately measure falling sphere.
The method of measurement time interval has several at present: 1. the method by range estimation and stopwatch, based on naked eyes and reaction speed
Degree makes experimental data very unreliable, and application condition is big.2. place laser beam at two positions point, fall to blocking by falling sphere sharp
The time difference of light determines time interval, and its drawback is that laser beam is thinner, it is difficult to ensure the accuracy of secondary shading, waste experiment
Personnel time, reduces the efficiency of experiment, and above two method is all confined to light-transmissive fluid in addition.3. put respectively at two positions point
Put electromagnetic induction coil, fall to causing the transformation period difference of coil current to determine the time interval of falling sphere, its fraud by falling sphere
End is that particularly super-viscous oil etc., the falling sphere of whereabouts can not cause electric current very delicately when fluid viscosity ratio to be measured is relatively big
Change.Measured experimental data randomness is bigger, needs constantly repeatedly the sensitivity of regulating winding electric current to ensure detection
Fall to falling sphere.Measurement environmental requirement more strictly can not be had electromagnetic field to do when measurement by line of induction ring type viscosimeter simultaneously
Disturb.Therefore so not only waste experimenter's time, also reduce the efficiency of experiment.Existing line of induction ring type viscosimeter is due to thick
Oil viscosity is excessive, is completely encapsulated on falling sphere and makes induction coil sensitive can not record position in whereabouts for the falling sphere accurately.
