AVR is specialized in processing various types of residual waste and converting this waste into energy and raw materials for households and businesses. In their plant in the Botlek (Rotterdam)…
The SIL-rating of a SIL loop degrades over time. Therefore the safety integrated function (SIF) of the safety instrumented system (SIS) must be tested with a certain frequency, which is usually determined…
It is essential to verify the functioning of every individual component of an overspeed protection system. This can be done during its installation, commissioning / turnarounds or troubleshooting. As this…
Overspeed situations on rotating machinery should be prevented at all costs. Even the slightest overspeed situation could lead to mechanical stress that causes rotating machine parts to deform. More serious…
Voting, regarding overspeed protection systems, can be defined by the number of safety loops that should switch to the safe state when an overspeed situation is detected. The desirable voting…
Overspeed protection systems have a critical function in the balance between the safety and availability of rotating machinery. These protection systems should be proof-tested periodically to verify the system logic…
February 2021 marked the global launch of Istec’s revolutionary SIL rated overspeed protection system: the SpeedSys 200. The system is highly adapted to growing market demands and challenges overly complex…
The leading standard for rotating machinery (API 670) states that (critical) rotating machinery requires a state-of-the-art overspeed protection system. The availability of electrical overspeed protection systems has grown ever since…
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…
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…
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…
