This trend is due to technological progress, increased user demand and the launch of new products. Especially in the domestic market, due to the accelerated industrialization process and the increased demand for precision industrial equipment, the market demand for viscosity measuring instruments has shown a rapid growth trend. In addition, rheometers and viscometers, as important components of viscosity measuring devices, are also expanding their markets. From a technical point of view, the technical level of viscosity measuring devices is constantly improving, especially in the field of rheometers. The technical level at home and abroad is constantly improving. Leading manufacturers focus on product development and progress by investing heavily in R&D activities, and expand their geographical presence by participating in mergers and acquisitions. Influence, these efforts not only improve the performance and accuracy of the products, but also meet the needs of different industries for viscosity measuring devices; from the perspective of market demand, viscosity measuring devices are widely used in many industries, such as food, beverages, paints, coatings, polymers, medicine, cosmetics, petrochemicals, etc. The development of these industries has promoted the increase in demand for viscosity measuring devices, especially in the process of controlling and monitoring the process parameters of products before and after production, viscosity measuring devices have become an indispensable tool, and the increasing concern about the consistency of finished products such as paints and other liquids has also prompted an increase in demand for viscosity measuring devices; and magnetorheological fluid viscosity measurement has become one of the hot topics in the academic field of magnetorheology. Therefore, the viscosity measurement device of magnetorheological fluid has become a research direction for scholars.

[0003] However, the traditional magnetorheological viscosity measuring device cannot meet people's needs. It has the following defects: First, there is no high-precision viscosity measuring device designed. For the viscosity detection of magnetorheological fluid, no high-precision measuring device is used. The measurement speed is relatively slow, the measurement accuracy cannot be guaranteed, the applicability is relatively poor, the operation is relatively complicated, and there are some technical requirements for operators, which cannot meet the needs of users; second, there is no constant temperature operation structure designed. For magnetorheological fluid, the viscosity value will change with the temperature. The lower the temperature, the higher the viscosity. When the temperature deviation of the viscosity fluid is ±0.5℃, the viscosity value deviation of some standard liquids will exceed The viscosity of the viscosity measuring device should be adjusted according to the experiment conditions. It takes a lot of time and manpower to disassemble and reassemble the device, and a certain depth of understanding of the device is required. For the experiment, a lot of time and cost are wasted.
