The sample measurement pond is fixed on liquid and solidifies on the support that detects part.
Described measuring vessel is slot type measuring vessel or tubular type measuring vessel.
The sample measurement pond partly is fixed on to solidify and detects on the support partly.Wig-wag can make the wallowing motion in support cycle and make the ball in the sample measurement pond of being fixed in produce back and forth rolling.
Solidifying to detect partly is used to make the sample measurement pond partly to swing and measure the rolling condition of ball wherein.The sensor of measuring the rolling condition of ball can adopt electro-optical pickoff or electromagnetic sensor.The sample measurement pond partly as adopt transparent material to make, sensor is placed on the path that ball rolls, when ball during by sensor, because ball causes that producing light changes photoelectric sensor can be produced and the relevant electric signal of ball motion; When using the metal ball, sensor also can use inductance type transducer or electromagnetic sensor.The same, when the metal ball rolls by sensor, sensor can be produced and the relevant electric signal of metal ball motion because the motion of metal ball causes inductance or electromagnetic change.When using the metal ball, the part of holding liquid can use non-transparent material to make.
After adding causes agent with fixed attention in the fluid sample measuring cell, solidifying its viscosity through certain reaction time initiation fluid sample sharply increases, and the viscous resistance that ball rolls is pushed the speed and slowed down, and the signal time difference strengthens, after the time difference signal vary stable, fluid to be measured forms gluey coagulum; Or fluid to be measured solidifies the formation decorating film fully, and ball rolls and stops, and time difference signal disappears.
Solidify the test section and detect and tell these, thereby determine that fluid to be measured produces the time of solidifying after adding causes agent with fixed attention along with viscosity changes the variation of the time difference signal that causes.
The computing formula of setting time is:
Sample setting time=T1+KT2
Wherein,
TI begins to produce the time that increases variation to the fluid to be measured signal time difference after adding causes agent with fixed attention;
T2 begins to increase to the metastable time of the signal time difference fluid to be measured signal time difference, or to time that time difference signal disappears;
K is compensation coefficient, constant or function.
The utility model has the advantages that, ball in the measurement mechanism owing to back and forth roll, therefore has good beating action during test in liquid, can avoid measuring different viscosities different densities liquid and the inhomogeneous measuring error of bringing that the adding that causes agent with fixed attention produces, improve the accuracy of measuring.Thereby this device is particularly suitable for the measurement of the setting time of the big liquid of range of viscosities.
