Product Description

TP-1102 Rotational Viscometer

TP-1102-model viscometer is the viscosity-measuring instrument for which the standard power adapter gives power supply, and it is applicable to 100~240V wide voltage belt, 50Hz or 60Hz power driving, and there are two speed types, namely 6-speed and 12-speed. See Diagram (I) for its structure and Table (I) for the details.
This is a typical coaxial cylinder viscometer in the annular space (shearing clearance) formed by placing the test fluid between the outer sleeve and the floater.
 

Application

In viscosity measurement, when the outer sleeve rotates at a set speed, the fluid will produce a viscosity resistance, and thus the viscosity of the fluid will be measured. When the outer sleeve produce a torque on the floater through the fluid, this torque acts on a precision spring, its deflection can be measured, and then make a comparison between the measuring result, measuring conditions and instrument constants. This system can imitate the real process in the industrial process.

Given a shearing rate, the coaxial cylinder rotational viscometer can make the viscosity measurement. This is a linear function relationship. For instance, the relational graph between the shearing stress and shearing rate is a straight line. In many cases, many fluids may not follow Newton's law, but their rheology is relatively close to Newton's law, so the viscometer can be still in use, and the viscosity can also be accurately measured. It is worth noticing  that  the  calibration  of the  recommended  TP-1102-model  viscometer  is  a  linear  calibration  following Newton's mode. This means that if the liquid sample does not conform to Newton's linear calculation method, and at this time, the viscometer will not be applicable. In this case, viscosity measurement and speed calculation will be subject to another linear calculation method, which is more applicable to the characteristics of such kinds of fluids.

When the standard outer sleeve, floater and torsional spring rotate in 300 rounds/minute, the measurement unit  of the viscometer  is centipoise  (or milli pascal/second). At  other rotating  speeds, the read data must be conducted  a  series  of simple  multiplying  conversion.  The  sixth  part  will  present  the  calculation  method  of viscosity of plastic fluids (such as drilling fluid). 

If choosing different rotating speeds or using different combinations of torsional spring-floater, the scope of shearing rate may have some changes. In order to expand the scope of shearing stress and thus measure all sorts of liquids, we have designed different series of torsional springs, which can carry out conversion easily.

Note: ( 1) Calculate the standard torsional spring (f = 1). For other torsional springs, multiply the scope of viscosity with f factor. (2) The minimum viscometer has calculated the minimum shearing stress and the minimum shearing rate. (3) For practical purposes, the minimum viscometer is only limited to 0.5 cP due to Taylor vortex.
