Measurement Units Of Vibration In Roll Mills

  • VIBRATION MONITORING SYSTEM OF STEAM TURBINE

    Vibration is measured either in terms of displacement, velocity or acceleration. Vibration displacement is always measured as Peak to Peak, a measure of the total excursion of the rotor or machine casing in MILS or MICROMETERS. Vibration velocity and Acceleration are measured as Zero to Peak or RMS. Units used are "inches

  • Practical Roll Techniques - Grinding & Balancing

    Roundness measurements indicate how close the roll face is to being a perfect circle. If a roll is not round, it will vary nip pressure in every rotation and cause vibration. This can cause roll cover barring or vibration further down the machine. In some cases it can cause MD caliper variation in the sheet.
