Accelerometer monitors machine condition

High output accelerometer has a 500mV/g sensitivity to minimise electronic noise and maximise voltage output to the monitoring instrument.

Wilcoxon Research 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 786-500 accelerometer 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 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.

The 786-500 is suitable for high speed and low frequency applications because of its superior broadband frequency response.

The +/-3dB frequency response of the accelerometer is from 0.2Hz to 14kHz.

The sensitivity is 500mV/g, with a tight 5% sensitivity tolerance.

The acceleration range is 10g.

The 786-500 accelerometer has an excellent broadband noise floor at 250ug.

The 786-500 high output accelerometer has a 500mV/g sensitivity to minimise electronic noise and maximise 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 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.
