| Abstract: | This paper introduces a new force balanced piston pressure gauge that is used mini and absolute pressure. It also describes its operation principle, pressure formula and verification etc. According to compare with standards, the principle and uncertainty of pressure gauge is tested. The results show that the uncertainty given by the manufacturer to measure uncertainty this piston is correct. |
