摘要
文章针对压力测试机的压力传感器在无压力时电桥的平衡问题及V/F转换的频率稳定问题进行探索,探讨了电桥数字电位器的调零及VFC32外围元件参数的计算方法。
This paper discusses the balance of electrical bridge when pressure sensor of the pressure testing machine has no pressure and frequency stability of V/F conversion. It also probes into methods of zeroing the digitally controlled potentiometer and calculating parameters of the peripheral components of VFC32.
