Rotating assemblies are often of fundamental importance within a production cycle. A sudden breakage can immediately stop production with very heavy economic damage.
It is therefore essential that they are kept under control so that they can be maintained before they are damaged.
Time monitoring of the vibrational level is normally the parameter used to verify the correct operation of the unit.
Increased vibration levels are a symptom of a problem that needs to be kept under control and diagnosed in good time. The reference values of the maximum
vibration tolerability thresholds can be easily obtained from ISO 2372 and ISO 10816 according to the type of machine.
The most economical and compact solution is certainly to install on the machine, permanently, one or more sensors that generate a current signal proportional to the level of vibration detected. Normally these sensors are connected directly to the supervisory system or PLC. This simple installation allows a continuous monitoring of the vibrational level that added to other process parameters, such as temperature, electrical absorption, etc... are able to provide a clear picture of the situation.
The distance between the supervision system and the vibration transmitter can be as much as hundreds of meters because the current transmission guarantees excellent immunity to electrical and electromagnetic disturbances.
The transmitters are, in general, very robust and resistant and are also normally available in ATEX construction for potentially explosive environments.
