A6500-UM- General purpose monitoring module
For shaft relative vibration measurement Shaft relative vibration modes are used to improve reliability for the most critical rotating equipment in the plant. This function, when combined with other CSI A6500 ATG monitoring modules, forms a complete API670 mechanical protection monitoring system
Applications include steam turbines, gas turbines, compressors and water turbines.
The main function of shaft relative vibration measurement is to drive the alarm and alarm by comparing the measured parameter with the alarm setting value
Relay outputs to accurately monitor shaft relative vibration and protect equipment in a reliable manner.
Shaft relative vibration consists of one mounted through the bearing housing or mounted inside the bearing to rotate the shaft or monitor the target mounting
A displacement sensor with a rotating shaft as the monitoring target on the bearing housing.

The A6500-UM piezoelectric sensor, sometimes referred to as shell absolute vibration measurement (as distinct from shaft absolute vibration), is used plus
Speed sensor or speed sensor that outputs an acceleration or speed value. The shell vibration monitoring clamp can monitor the shaft
The acceleration value or velocity of the housing in g’s (in millimeters per second (inch 1 second)). Due to pass
The sensor is mounted on the housing, so the vibration generated by the housing can be affected by many different factors, including the rotor
Moving foundation and shell stiffness, blade vibration, adjacent equipment, etc.
