Capsule Introduction

Metallic diaphragms and capsules are used to transfer the pressure (relative and absolute) or pressure difference put on them into central displacement or central concentrated force of the diaphragms. They can also work as isolation elements between instruments and tested mediums to protect the instruments and to insure measuring accuracy, or as flexible sealing apparatus that travel according to the variation of pressure and vacuum. They boast many advantages like simple structure, reliable performance, large measurement range, low prize, etc. They are widely used in fields like automation instruments, aviation, aerospace, navigation, petroleum, chemical engineering, meteorology, etc.
