Acceleration and Acceleration EnvelopeIn my installation, I have a piezoelectric accelerometer used to monitor vibration on a pump. This accelerometer is connected to Bently Nevada Dual Accelerometer monitor 3300/25 which measures the acceleration in g. On the other I have a SFK Mechanical Condition Detector which measures the vibrations in terms of Velocity (meters/second), Acceleration Enveloping (gE) and Temperature (Deg C).
I want to check the function of the accelerometer and the Bently Nevada monitor. Is it ok to compare the acceleration measured by Bently Nevada monitor (in g) with the value measured by the Mechanical Condition Detector (in gE)? If so, how do I convert the reading in gE to g?
