HYDAC傳感裝置壓力傳感器電子壓力開關(guān)EDS410
閱讀：1275 發(fā)布時間：2018-1-12Electronic pressure switches offer a multitude of advantages in comparison with mechanical pressure switches and contact manometers. They convince though greater accuracy, freedom from wear, long-term stability, simpler operation and the high number of switching cycles, among other things.
