MR660
Fiber Optic Accelerometer
The MR660 Series Accelerometer provides an innovative solution to measure vibration and movement in high voltage or ATEX environments. The MR660 Accelerometer system employs a highly sensitive MEMS membrane to provide a robust system capable of producing an output signal of 100mV/g pk-pk.
The MR660 Accelerometer is designed for a variety of customer applications such as Wind Turbine Blade, Electric Train Pantograph, and Generators & Transformers.
Micronor delivers custom tailored sensors to suit a specific application. Contact Micronor for configurations other than the standard sensors available.
