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…
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…
Rotating machinery such as turbines, pumps and compressors are continuously subjected to major mechanical forces. As most of these machines are critical to the process, systems are implemented with protection…
Choosing the right speed sensor for an application is of crucial importance for an accurate and reliable measurement. After all, the signal of the sensor is the input for an…
Rotating machines are often very critical to process plants. The reliability and availability of these machines must be guaranteed at all times, as failure to do so may have catastrophic…
In a previous article, we wrote about 11 important considerations for choosing the right accelerometer. However, to achieve reliable measurement results, the mounting method is crucial for maximizing accuracy. Various…
A turbine is designed to reach a maximum number of revolutions per minute (rpm), where the blades of the turbine can achieve enormous speeds. This limit must not be exceeded,…
Safety Integrity Level (SIL) SIL stands for Safety Integrity Level (EN-IEC 62061) and is a part of Functional Safety. SIL is a method to assess electrical, electronic, and programmable electronic…
For monitoring and overseeing rotating machines (pumps, motors, fans, gearboxes), you naturally want to use reliable and high-quality vibration monitoring systems. In this article, we discuss 11 key points to…
It is very important that machines/installations in a factory are operational, especially when a factory needs to operate day and night. Unplanned downtime is highly undesirable, as it incurs high…
“20 billion is lost each year due to unplanned downtime” (Automation.com, 2016). An effective way of predictive maintenance has been an important topic within the industry for years. Often, it…
