IMI Sensors 685B系列电子振动开关旨在提供持续的机械保护
ELECTRONIC VIBRATION SWITCHES Series 685B
DESIGNED TO PROVIDE CONTINUOUS MACHINERY PROTECTION

电子振动开关提供高精度的连续监测，具有良好的重复性和可靠性。它们需要电力来操作和利用电子振动传感器提供的输入信号。完全可配置的开关可以使用内置的弹丸加速计，也可以连接到远程加速计。Electronic vibration switches offer highly-accurate continuous monitoring with excellent repeatability and reliability. They require power to operate and utilize an input signal provided by an electronic vibration sensor. The fully-configurable switch can either utilize either a built-in pellet accelerometer or be wired to a remote accelerometer.
