Description

Technical Field

[0001] The utility model relates to the field of diaphragm capsule and diaphragm measurement, in particular to a device for measuring the height of a diaphragm capsule and diaphragm. Background Technique

[0002] Diaphragm capsules and diaphragms play an important role in pressure measuring instruments. As measuring elements, they are used to measure different pressure ranges and environments. Diaphragm capsules are mainly used to measure tiny pressures, while diaphragms are used to measure low pressures not exceeding several megapascals and can also be used as isolation elements. When selecting a thin film thickness gauge, factors such as the measurement range, measurement accuracy, and use environment need to be noted to ensure the accuracy of the measurement results. The structural compositions and measurement principles of diaphragm capsules and diaphragms are different, resulting in different displacement amounts and applicable environments for them. For example, the displacement of a flat diaphragm is the smallest, that of a corrugated diaphragm is the second, and that of a diaphragm capsule is the largest. If a larger displacement is required, it can be achieved by connecting several diaphragm capsules in series to form a diaphragm capsule group.

[0003] Diaphragm capsules and diaphragms mainly include flat diaphragms, corrugated diaphragms, and spherical diaphragms. These diaphragms are made of metal or non-metal materials and have different surface shapes for different application scenarios. However, regarding the measurement of their heights, there is no dedicated method directly targeting "measuring the height of diaphragm capsules and diaphragms". Diaphragms and diaphragm capsules are mainly used for pressure measurement. Their height changes are usually related to the pressure they bear. In a pressure measuring instrument, the displacement of a diaphragm or diaphragm capsule is converted into a measurable signal (such as an electrical signal) through a certain mechanism to indicate the pressure. Therefore, directly measuring the height of a diaphragm capsule or diaphragm may not be a conventional operation, but rather measuring the displacement generated by them due to pressure changes. However, since there are many styles of diaphragm capsules and diaphragms, multi-directional detection is required when detecting each different diaphragm capsule and diaphragm, and the positions of the diaphragm capsules and diaphragms need to be continuously changed, which is time-consuming and laborious. Therefore, we propose a device for measuring the height of diaphragm capsules and diaphragms to solve the above problems. Content of the Utility Model
