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…
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…
