Vibration monitoring is used in applications such as traditional instruments that monitor machine health for maintenance and safety.
For these type of applications, the objective is to correlate observable vibration with typical wear-out components, such as bearings, gears, chains, coils, and valves.
Another application is high-speed automation equipment that monitors vibration to trigger feedback control of lubrication, speed, or belt tension. Vibration-sensing usually focuses on the magnitude of the oscillation, not on absolute position tracking, so sensing linear motion with MEMS accelerometers is sufficient for capturing the required information.
Physical Logic’s in-plane bulk micromachining accelerometers can be used in various vibration sensing applications.
Physical Logic’s MEMS accelerometers are designed and manufactured in Israel. All products are ITAR free and are also offered as export control free.
