7 – 11 mm/s 0,28 – 0,43 in/s
Large vibrations. Bearings running hot. Bearing wear-out cau-
ses frequent replacements. Seals wear out, leakage of all kinds
evident. Cracks in welding and concrete foundations. Screws
and bolts are loosening. High noise level. Plan
action soonest. Do your best to discover the cause. You are
wearing down investments quickly.
•
11 – mm/s 0,43 − in/s
Very large vibrations and high noise levels. This is
detrimental to the safe operation of the machine. Stop
operation if technically or economically possible. Few machi-
nes can withstand this level without internal or
external damage. Reduce any further running time to an abso-
lute minimum.
Vibration Measurement Instruments
Important information
Safety precautions
Vibration measurement and balancing involves measurement on rotating machines.
Keep a safe distance to rotating parts and secure transducers and transducer cables
from rotating parts. Always follow internal, local and national security
regulations! When working with weights on the rotor always secure the start
switch with a locker and also use the emergency switch for double safety. This is
especially important when the machine is remote controlled.
