Excessive vibrations on rotating equipment like pumps, gearboxes, turbines and compressors are a clear sign that the equipment is not functioning properly. Equipment that is showing excessive vibrations will most…
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)…
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…
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…
SpeedSys 200 & 300 are SIL-rated overspeed protection systems for rotating machinery. The systems are highly adapted to growing market demands and challenge overly complex rack-based systems. This article describes…
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…
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…
