New high output accelerometer for high speed and low frequency vibration monitoring

The 786-500 accelerometer is suited to condition monitoring and predictive maintenance of a variety of rotating equipment. Slow speed applications benefit from the strong 500 mV/g output of the 786-500 because it overcomes data collector noise that can mask indicators at low frequencies. In high speed applications, the 786-500 provides five times the sensitivity of general purpose accelerometers for better detection of low level vibrations.
