High Output Accelerometer from Wilcoxon
Germantown, MD — Wilcoxon Research, a Meggitt group company, has released a new high output accelerometer for machinery health monitoring. The model 786-500 accelerometer has a high output and broadband frequency response for multi-use applications. The device is suited to condition monitoring and predictive maintenance of a variety of rotating equipment.
Slow speed applications benefit from the strong 500mV/g output of the accelerometer because it overcomes data collector noise that can mask indicators at low frequencies. In high-speed applications, it provides five times the sensitivity of general purpose
accelerometers for better detection of low level vibrations. The accelerometer is suitable for high-speed and low-frequency applications because of its superior broadband frequency response. Its ±3dB frequency response is from 0.2Hz to 14kHz. The sensitivity is 500 mV/g with a tight 5 percent sensitivity tolerance. The acceleration range is 10g. The 786-500 accelerometer has an excellent broadband noise floor at 250µg.
The 786-500 high output accelerometer has a 500 mV/g sensitivity to minimize electronic noise and maximize voltage output to the monitoring instrument. The ability to provide a stronger, cleaner signal is important to high speed monitoring applications, such as turbocompressors and precision balanced high speed machinery, in which detecting low amplitude vibrations is critical. The excellent low frequency response makes it suitable 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.
