End-users that operate (critical) rotating machinery have a legal obligation to implement a suitable and verifiable safety instrumented system (SIS). Safety Integrity Level (SIL, IEC 61508), one of the more…
In the past, overspeed turbine protection systems were often designed by the turbine OEMs themselves as part of the mechanical system. These mechanical protection systems are still in use, especially…
Choosing the right speed sensor for an application is of crucial importance for an accurate and reliable measurement. After all, the signal of the sensor is the input for an…
The ST5484E is a SIL2 certified vibration transmitter for vibration measurements on bearing housings and is suitable for rotating machinery and reciprocating compressors. With the certification, the transmitter is applicable…
There are different system structures to facilitate machine vibration protection – one more advanced than the other. Which method is used depends on the application and the criticality of it.…
In 1939, T.C. Rathbone published a paper called ‘Vibration Tolerance‘ in the magazine Power Plant Engineering. The ideas in this paper are considered the foundation of modern industrial vibration measurements.…
Monitoring machine vibrations affords greater control over the safety and availability of the equipment. It reduces unscheduled downtime and potential damage or failure can be resolved at an early stage.…
When it has been decided to start a machine condition monitoring program on a machine to start a predictive maintenance strategy, it appears that there a various possibilities how this can…
To ensure process safety in a factory, protective layers are used; risk-reducing measures. These protective layers can be related to people, the process, or the plant (and machinery). The greater…
The management of a company is always ultimately responsible for the safety of its employees. In the process industry, it is crucial to pay close attention to safety assurance, as…
A turbine is designed to reach a maximum number of revolutions per minute (rpm), where the blades of the turbine can achieve enormous speeds. This limit must not be exceeded,…
