1-axis accelerometer MR661

fiber opticIP67

The round MR661 sensor is the sensor for the fiber optic acceleration measuring system MR660 for 1-axis measurements. The fiber optic accelerometer MR660 measures accelerations (vibrations) in areas where electronic or electromechanical transducers fail. This includes areas where there are strong electromagnetic fields, such as transformers, generators, trains, pantographs. The sensors work on an optical basis and are purely passive. The signals are transmitted to the evaluation unit over a distance of up to 200m without interference. We can supply customer-specific feedthroughs, cabling or sensor brackets for all applications.
