DESIGN AND CONSTRUCTION OF A COMPUTERIZED VISCOMETER / RHEOMETER
 
Resumo :
A COMPUTERIZED VISCOMETER / RHEOMETER WAS DESIGNED BASED ON A COUETTE CELL AND A HELICAL SPRING TORQUE METER, BOTH TAKEN FROM AN OBSOLETE COMERCIAL RHEOMETER. THE APPLICABLE SHEAR RATE IS FROM 50 TO 500 (1/S), THE MEASURABLE RANGE OF SHEAR STRESS IS FROM 2.7 TO 70 MPA, AND CALCULATED RANGE OF VISCOSITY IS FROM 5 TO 1400 MPA.S. THE USE OF A STEPPING MOTOR TO DRIVE THE ROTATING BOB SIMPLIFIES BOTH THE ELECTRONICS AND THE CONTROL PROGRAM. PRELIMINARY RESULTS WITH LUBRICANT OILS HAVE SHOWN GOOD AGREEMENT WITH LITERATURE DATA. KEYWORDS: VISCOMETER, RHEOMETER, VISCOSITY, RHEOLOGY, RHEOMETRY
