磁悬浮转子真空计是一种采用微处理机技术的新型高精度真空计。本文介绍了CXG-1型磁悬浮转子真空计的工作原理、结构和电路设计,以及用Z-80单板机完成实时压强测量的方法。简述仪器性能测试的方法与结果。该仪器用于真空标准比对的传递规和真空量值传递的副标准规,也为高精度真空测量与控制提供了一种重要手段。
Magnetic suspension rotor vacuum gauge is a new type of high-precision vacuum gauge using microprocessor technology. This paper introduces the working principle, structure and circuit design of the CXG-1 magnetic suspension rotor vacuum gauge and the method of real-time pressure measurement with the Z-80 single-board machine. Brief description of the method and result of instrument performance test. The instrument is used in the vacuum gauge standard and the vacuum gauge transmission standard gauge, but also for high-precision vacuum measurement and control provides an important tool.
