摩擦起电噪音发生在机械弯曲的信号电缆中。当加速度计这类压电晶体传感器与高输入阻抗放大器一起使用,以测量低频范围内(典型地是从另赫,即静止的,到100赫)的低电平信号时,这种摩擦起噪音是十分重要的。于是 Vibro-Meter(瑞士)Quality 和 Reliabrlity Departm-ent 执行了一项包括为选择低噪音电缆所需要的全部数据的试验计划.(在联合王国的 Vibro-Meter 公司是柴郡,Stockport 的 Vibro-Meter Ltd).
Frictional electromotive noise occurs in a mechanically bent signal cable. This frictional noise is used when accelerometers such piezoelectric crystal sensors are used with high input impedance amplifiers to measure low-level signals in the low frequency range, typically from a different, ie, standstill, to 100 Hz It is very important. So Vibro-Meter (Switzerland) Quality and Reliabrlity Departm- ent implemented a pilot program that included all the data needed to select a low-noise cable (Vibro-Meter in Cheshire, UK and Vibro-Meter in Stockport Ltd).
