On our expert blog we publish in-depth articles on our expertises: vibration, speed and SIL.
4 reasons why overspeed protection systems should not be overly complex
Overspeed protection systems have one of the most important functions regarding safety measures for rotating machinery. As such, these systems require advanced safety functions to detect overspeed and excessive acceleration…
3 types of target objects for speed measurements
To measure the rotational speed of a shaft, it is necessary to have the right target for the contactless-sensing speed sensors to be able to generate an accurate signal. In…
Proof tests of an overspeed detection system (ODS) using an on-board function generator
There are several overspeed detection systems (ODS) on the market that are equipped with an on-board function generator for online test purposes, and this feature is frequently found in ODS…
What hardware is required for a remote vibration monitoring system?
In a previous article we discussed 4 reasons to consider remote vibration monitoring. In this article we will further discuss the various options for implementing such systems. We discuss various…
4 reasons to install a remote vibration monitoring system
Monitoring the vibration behaviour of (critical) rotating machines is crucial to guarantee the reliability and availability of these machines. The vibration behaviour of rotating machinery is therefore closely monitored for…
The difference between SIL certification by design and proven in use
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…
Mechanical overspeed protection or electronic overspeed protection?
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…
