In the production process of the pharmaceutical and medical equipment industry, especially the semiconductor industry such as chips and memory, ultrapure water is used. The water pressure measurement of its pipeline and its storage tank requires accurate measurement. The traditional method is to use ordinary pointer pressure. Meter testing; now the process in this industry requires accurate measurement, and its data needs to be uploaded for real-time monitoring, and the whole process data of pressure changes is collected and monitored by a computer, which is used to store, control, analyze and trace, and monitor the production process throughout the process; Graeff The pressure and temperature measurement of the husband sensor solves this difficulty very well.
