Permanent machine monitoring

Permanent machine monitoring (monitoring) is used for security. Originally this was to protect the machine, nowadays the HSE (Safety, Health and Environment) protection of the environment is more important. High requirements apply to vibration monitoring systems for this.

Machine monitoring by means of vibration measurements traditionally protects your valuable machines against the consequences of overload or incipient damage. It is not a protection against loss of production because it does not give an early warning.

Traditionally, vibration monitoring has been applied to turbines and generators in power generation since the XNUMXs. This was often required by the insurers in order to machine damage to these very valuable machines. This was followed by the fast rotating centrifugal compressors in the oil and gas industry, including the petrochemical and other basic chemicals such as ammonia production.

Because a chain is only as strong as the weakest link, other important machines in the process were also monitored, such as combustion air fans, flue gas fans, cooling fans, etc. Previously this was done with mechanical vibration switches, but due to poor reliability these have been almost completely replaced by electronic systems with features that prevent false alarms. Only in cooling fans and reciprocating compressors (because of the low speeds both are the most unsuitable applications) they are sometimes encountered. The only reason that can be found for this is that it used to be done that way.

Another reason to monitor rotating machines for vibration is the risk of personal injury due to an increased risk from the process. Well-known examples of dangerous machines are centrifuges and hammer mills. Based on the harmonized EU standards and the RIE, it is a legal obligation to monitor these machines in terms of vibrations, just like with fans in explosion-hazardous areas.
