Vibration-Monitoring Sensor Offers Broadband Frequency Response

The 786-500 high-output accelerometer has a broadband frequency response that serves both high-speed and low-frequency applications. It’s well suited to condition monitoring and predictive maintenance of a variety of rotating equipment. Slow speed applications benefit from the 500 mV/g output because it overcomes data collection noise that can mask indicators at low frequencies. In high-speed applications, the device provides five times the sensitivity of general-purpose accelerometers for better detection of low-level vibrations. The accelerometer has a +3dB frequency response over 0.2 Hz to 14 kHz. Sensitivity is 500 mV/g with a 5% sensitivity tolerance, acceleration range is 10 g, and the broadband noise floor is 250 µg. The accelerometer’s excellent low-frequency response makes it ideal for slow-speed condition monitoring applications such as cooling tower fans, slow speed gearboxes, wind turbines, food processing equipment, slow speed agitators, paper machine rollers, and large fans.
