On our expert blog we publish in-depth articles on our expertises: vibration, speed and SIL.
Case study AVR: replacing a Bently Nevada BN3500 to an Istec SpeedSys 200 overspeed detection system
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)…
How to maintain the SIL-rating of a machine protection system
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…
4 first checks when installing, commissioning and troubleshooting an overspeed protection system
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…
6 causes of overspeed on rotating machinery
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…
Why periodic proof-tests of overspeed protection systems are essential
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…
How Istec realizes vibration protection and condition monitoring at a power plant
Recently we have published a series of articles about (remote) condition monitoring. We described 4 reasons to install a remote vibration monitoring system (1) and listed the necessary hardware for…
5 ways SpeedSys changes the overspeed market
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…
Application note: The challenge of monitoring vibration and rod drop
Explained: how and when to monitor vibration and rod displacement Reciprocating compressors are among the most critical machinery in industries such as (petro)chemical, power and oil and gas. As opposed…
3 ways of monitoring your pumps for cavitation
Cavitation is a widely known problem that occurs to pumps and results in significant damage and other undesirable consequences. To avoid damage a pump should be monitored for the formation…
A modern approach for overspeed protection
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…
