Product Manufacturing Process

The manufacturing process of capsule pressure gauges involves precision engineering to ensure high sensitivity and accuracy in low-pressure applications. Firstly, the capsule elements are created from thin, corrugated metal diaphragms, often welded together to form an airtight chamber. High-precision tools are used to ensure the diaphragms have uniform thickness and corrugation, which is critical for consistent performance. The movement mechanism, including gears and linkages, is meticulously assembled to amplify the capsule’s deformation into a readable dial movement. Quality control is stringent, with each gauge tested under controlled conditions to ensure it meets performance specifications. Thus, the manufacturing process of capsule pressure gauges focuses on precision and reliability, as supported by numerous scholarly articles and industry standards, making these gauges an essential tool for accurate low-pressure measurements.
