Tech Note 114: Double Integration of Vibration Signals
STI recommends performing double integration (Acceleration to Displacement) when required by using a CMCP793V Velocity Output Accelerometer and a CMCP535(A) Transmitter or Monitor. As each integr
Journal Bearings
Industrial machinery with high horsepower and high loads, such as steam turbines, centrifugal compressors, pumps and motors, utilize journal bearings as rotor supports.
Comparing Vibration Readings
Comparing vibration level readings taken by different types of instruments and transducers can be very confusing and can lead to mistrust of the systems involved. Knowledge of how to prop

What is Vibration Monitoring?
Since the invention of the wheel Vibration has been an issue. Once wheels were mounted to an axle or shaft, out of roundness and unbalance became prime concerns. As the industrial revolution arrived
Measuring Vibration
Measuring Vibration Measuring vibration using modern vibration sensors is relatively inexpensive and easy to do! Knowing the vibration levels of rotating machinery and related accessories
Overhung Centrifugal Pump
Overhung Centrifugal Pumps are unique in that the Impeller is cantilevered outboard of the pumps bearings. This design allows for an open suction at the outboard end and reduces the number of shaft s
