GRAEFF 历史History

Walter Graeff（沃尔特·格拉夫）

1930年，Walter Graeff（沃尔特·格拉夫）发明第一支压力传感器转换机构，在此机构中,膜片、弹簧或Bourdon管的移动量变为电量部分,压力膜片成为电容部分,指示器可动机构成为电位计分支，实现了压力测控装置。

In 1930, Graeff (Graeff) invented the first pressure sensor conversion mechanism, in which the movement amount of the diaphragm, spring or Bourdon pipe becomes the power part, the pressure diaphragm becomes the capacitor part, and the indicator movable mechanism becomes the potentiometer branch, realizing the pressure measurement and control device.
