Description

Viscometer suppliers provide detailed explanations on the related knowledge points of viscometers:
Using single chip control, it is an intelligent instrument with data acquisition, processing and Chinese character display. The instrument controls the stepper motor to run accurately and smoothly according to the set speed, and rotates the rotor through the play ribbon. When the rotor is not subjected to resistance, the rotor and the motor rotate synchronously; when the rotor is subjected to the resistance of the measured liquid, the rotation of the rotor will lag behind the motor. When the tension of the hairspring and the resistance of the liquid reach equilibrium, the angle of the rotor lagging behind the motor is fixed. By measuring the opening angle, the instrument calculates the viscosity of the measured liquid and displays it on the LCD screen according to the set speed and rotor.
Viscometer is a physical property analyzer that measures fluid viscosity. Viscosity is a physical property of a fluid substance. It reflects the internal frictional forces between molecules when the fluid is subjected to external forces. The viscosity of a substance is closely related to its chemical composition. In industrial production and scientific research, the composition or quality of a substance is often monitored by measuring the viscosity.
In the process of measuring with a viscometer, there are many factors that affect its viscosity value. Let's talk about it carefully.
① Temperature affects molecular cohesion
② Storage volume of rotor in sample
③ Test speed of non-Newtonian fluid
④ Verticality of installation of viscometer
⑤ Concentricity of connecting rotating rod parts
⑥ Machining accuracy of rotor shape
The software of the viscometer system mainly includes the generation of vibration excitation signals, data processing and the realization of control algorithms. The overall idea of ??the system software programming is to initialize the processor control port and the AD converter port first. After the viscometer is turned on, the system samples the data periodically and obtains the amplitude signal to feedback control the vibration coil drive current to adjust the amplitude. Keep it at a constant value, and then process the signal sent from the power compensation part and display it on the user interface.
