Yuncheng Printing Plate Group Co., Ltd. was established in 1984 and is involved in multiple industries, including gravure printing, embossing, flexographic printing, printing, and equipment manufacturing. Currently, Yuncheng Printing Plate Group operates 126 production facilities. Among these, 92 subsidiaries are located in 23 provinces (cities, autonomous regions) across China, while 34 subsidiaries are established in 22 countries overseas. Yuncheng Printing Plate Group maintains global leadership in management standards, technological processes, and product quality, with a market share exceeding 70% in high-end product segments. It stands as a leading enterprise in the global printing plate industry.

In plate-making equipment, copper sulfate solution plays an important role, especially in the corrosion process of metal plates, where its density directly affects the plate-making results. By accurately measuring the density of the copper sulfate solution, it is possible to ensure that the solution’s concentration remains within an appropriate range, thereby avoiding plate-making quality issues caused by excessive or insufficient concentration. For this purpose, the company selected Xi’an Yunyi’s “Tuning Fork Density Meter” for online measurement.

The XY-886 tuning fork density meter produced by Xi’an Yunyi uses advanced tuning fork vibration technology to measure liquid density with high precision. It monitors changes in the density of copper sulfate solution in real time and promptly reflects changes in liquid parameters during the corrosion process, such as excessive or insufficient concentration, so that corresponding measures can be taken to ensure the quality and reliability of the printing products.

This product features the following characteristics:

1>High corrosion resistance, with the fork body and liquid-contacting parts made of 304/316L/HC276/titanium alloy/zirconium, etc., supporting customization, and capable of stable operation even in harsh environments;
2>Excellent temperature resistance, with an internal PT1000 temperature sensor covering a range from -30°C to 150°C, meeting the needs of various application scenarios;
3>Strong interference resistance, unaffected by fluid properties (viscosity, pressure, density, etc.), capable of measuring the density of mixed media containing solids or bubbles;
4>Wide application range, providing reliable solutions for density measurement of various media such as lime slurry, ammonia water, mineral slurry, coal slurry, pharmaceutical solutions, concentrated solutions, hydrofluoric acid, hydrochloric acid, and sulfuric acid;
5>Plug-and-play, maintenance-free design significantly reduces installation and commissioning complexity, eliminating the need for regular replacement or maintenance.

Yuncheng Printing Plate Group needs to regularly measure the density of copper sulfate solution during the production of various gravure plates, embossing plates, ceramic plates, die-cutting plates, hot stamping plates, soft gravure plates, and flexographic plates. Before formal measurement, the XY-886 tuning fork density meter is calibrated and installed on the storage or pipeline of the copper sulfate solution in the printing plate factory to ensure that the sensor is fully submerged in the solution, thereby ensuring the accuracy of the measurement results.

Based on the properties of the copper sulfate solution and measurement requirements, set parameters such as measurement range and accuracy, start the tuning fork density meter, and begin density measurement. The instrument will automatically record and display the measurement results. By analyzing the density changes of the copper sulfate solution, you can promptly adjust the production process and formula.

As a high-precision analytical instrument, the tuning fork density meter plays an important role in industrial density measurement. The XY-886 tuning fork density meter produced by Xi’an Yunyi utilizes advanced tuning fork vibration technology to fundamentally address the issue of minimal frequency variation, thereby enhancing the accuracy and stability of density measurements. It has been widely adopted across multiple industries and has received positive feedback from users.

In addition to tuning fork density meters, Xi’an Yunyi also offers a wide range of industrial instruments, including circular gear flow meters specifically designed for high-viscosity liquids, the next-generation intelligent gas measurement Roots flow meters, smart wireless instruments connected to an IoT cloud platform, high-precision and high-stability digital pressure gauges, as well as cost-effective pressure sources and piston-type pressure gauges for measuring pressure parameters. These instruments provide comprehensive solutions ranging from basic measurement to advanced intelligent monitoring, capable of meeting the diverse needs of various industries and application scenarios.
