MR660 Multi-Axis Fiber Optic Accelerometer

MR660

Multi-Axis Fiber Optic Accelerometer System

The MR660 Series Multi-Axis Fiber Optic Acceleration Sensor System provides an innovative solution for measuring vibration and movement in high voltage or hazardous environments. Typical applications include Pantograph monitoring, Wind Turbine Blades, MRI, Transformers, Generators, Mining, and Oil & Gas.

Sensors and Controllers are available in 1-, 2-, and 3-Axis configurations. The MR660 Acceleration Sensor employs a highly sensitive MEMS membrane to provide a robust system capable of producing an output signal of 100mV/g pk-pk with a bandwidth of 0.5Hz to 1000Hz.

Micronor delivers custom tailored sensors to suit a specific application. Contact Micronor for configurations other than the standard sensors available.
