摘要
近十余年来压力计量技术有了明显的进展。本文介绍了我国微压、中压和高压方面国家基准的改进和我国动态压力校淮技术的进展情况。对于活塞式压力计的性能改进以及新型的强制平衡式活塞式压力计和数字式活塞式压力计的研制成功作了不少描述。还介绍了数字式压力控制器的迅速发展及其对压力计量工作的影响。
Pressure measurement technology has been developed considerably in the past decade. This paper will introduce the improvement of national primary standard for low pressure, middle pressure and high pressure, and the development of dynamic pressure calibration technology in China. Several improvements on performance of piston gauge and the achievements of the novel forced balanced piston gauge and the digital piston gauge are described here. This paper also introduces a rapid development of the digital pressure controller and its influence on pressure calibration procedure.
