Mathematical rotary viscometer instructions for use
The ME-NDJ-series rotary viscometer is a digital display type viscometer with high subdivision driving stepping motor, 16-bit microcomputer processor and LCD with night vision function. The instrument has stable and accurate rotation speed, clear keystrokes, program design, and easy operation. The screen directly displays the viscosity, rotation speed, percent scale, rotor number, and the maximum viscosity value of the selected rotor at the current rotation speed. The main control board and subdivided drive board all adopt patch technology. The circuit design adopts the most advanced microcomputer processor at present, and the structure layout is reasonable and compact. Provide RS232 interface, print interval can be set by the user. The full scale of the instrument and the linearity of each file are all calibrated and calibrated through the PC interface, and its performance and functions have reached the advanced level of the same type in foreign countries. The ME-SNB-series rotary viscometer is an upgraded product based on the ME-NDJ-series rotary viscometers. In addition to the performance and features of the ME-NDJ-series rotary viscometers, the ME-SNB-series rotary viscometers offer a wider measurement range, improved speed selection for full stepless speed change, full data acquisition via a PC interface, and connection to a PC. Many mathematical statistical analysis tasks such as automatic operation, data saving and comparison of historical data.
The principle of mathematics rotary viscometer measurement: The mathematical rotary viscometer must firstly detect the zero position after starting up. This operation is usually carried out without installing the rotor, and then it is installed coaxially within the radius R1 inside the outer radius R2. The barrel is filled with viscous fluid. The synchronous motor rotates at a steady speed. The scale disc is connected successively. Then the inner cylinder (ie, the rotor) is rotated by the hairspring and the rotary shaft. The inner cylinder (ie, the rotor) is subjected to a fluid-based viscous torque. The greater the effect, the greater the torque produced by the balance spring and the greater the scale that the pointer indicates on the dial. Multiply the reading by a specific factor to obtain the fluid's dynamic viscosity.
