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
Tech Note 115: Shunt Resistors
Occasionally a customer will ask us how to interface one of our Transmitters with a 4-20 mA output to a DC Input Field IO Card. What is important to understand is that even a 4-20 mA Input Card u
Custom Cabinets & Panels
STI has provided hundreds of integrated custom cabinets and panels containing a wide variety of instrumentation. SKF Condition Monitoring’s M800A, Monitor Interface Module (MIM) Multilog (LMU), Mecha
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
