Why Monitor Vibration ? ■ Monitoring vibration reduces downtime –Use predictive maintenance programs –Plan maintenance more efficiently –Monitor machine run time ■ Vibration is often the result of components that are: –Imbalanced –Misaligned –Worn –Loose –Improperly driven Detecting increased vibration early helps reduce machine damage and avoid failures

Condition Time Preventive Maintenance Predictive Maintenance Operator Care Run to Failure Vibration analysis Low risk Alarm High risk With Predictive Maintenance Program Oil analysis Temperature rise Audible noise Too hot to touch Mechanically loose Catastrophic failure Health Degradation Curve

Predictive Maintenance Monitoring Local Indication ((( Send threshold signal to a central location Send vibration & temp data via the gateway to the control system for collection & trending Vibration & temperature data is generated to provide health status of machines

Vibration Measurement Overview ■ To monitor vibration velocity, acceleration and displacement can be measured –Velocity = speed of movement Most uniform response over wide range of machine frequencies Considered universal measure of machine integrity in relation to alignment and balance –Acceleration = rate of change in speed Useful in high frequency measurements High frequency monitoring above 2 KHz is used to detect bearing and gearing vibration –Displacement = distance moved Useful below 5 Hz Structural vibration (buildings, bridges, earthquakes, etc.)

Vibration Measurement Overview ■ Velocity is the best measure of vibration because it mutes frequency dependent effects Displacement is used for measuring low frequencies: low RPM Acceleration is used for measuring high frequencies: bearing frequencies Velocity is best over a wide frequency range

Vibration Measurement Overview ■ The Banner QM42VT1 sensor uses an FFT (Fast Fourier Transform) to convert the vibration signal from a time domain to a frequency domain in order to calculate the velocity Time & Frequency Domain Time Domain waveform shown as many different frequencies & amplitudes

Vibration Measurement Overview RMS Velocity ■ RMS (root-mean-square) is in essence an averaging operation that conveys the effective energy within a signal ■ RMS velocity is the most common and effective measure of machine vibration severity in rotating equipment. –It is an indication of the vibration energy produced by the machine –It is expressed in inches per second (in/s) or millimeters per second (mm/s)

■ The Banner QM42VT1 uses a MEMS based accelerometer as its core sensing element for vibration ■ It uses advanced signal processing techniques to output a digital signal that represents a true RMS velocity between 10 and 1,000 Hz. ■ Vibration RMS velocity and temperature data can be trended so that the user can set thresholds and alarms based on machine history ■ The ISO Vibration Severity Chart can be used as guidance to set threshold levels. Vibration Measurement Overview

Set Alarm Levels ■ The ISO vibration severity chart is a well established standard that is based on historical machine vibration data. ■ It defines acceptable limits of vibration severity, using RMS velocity, and can be used to set vibration alarm levels. ■ Absolute levels of vibration will vary based on many factors including type of machine, mounting, etc. ■ Temperature alarms can be set up to 80°C

((( Example in/s The LCD readout for input 1 is ÷ 10,000 =.097 RMS velocity in/s =.097 Set Alarm Levels How to convert the holding register representation into RMS velocity: Example mm/s The LCD readout for input 2 is 2,490 2,490 ÷ 1,000 = 2.49 RMS velocity mm/s = 2.49 Vibration alarm levels can also be set by establishing a vibration baseline for a machine: Use LCD display on DX80 Gateways and P6 Nodes to calculate RMS velocity (see below) Trend RMS velocity over time to establish baseline Set alarm level at 1 ½ - 2 times the baseline vibration level P6 Node
