Turbine Supervisory Instrumentation – a forgotten art?

Large steam turbines employ a suite of supplementary measurements not found on other types of rotating machines.

VM600Mk2 – No Customer Left Behind

When we introduced the VM600 platform 21 years ago, we “broke the mold” by moving away from application-specific modules. The industry paradigm at that time was generally one module for accelerometers, another for velocity sensors, another for proximity sensors, another for thrust, still another for case expansion, yet another for speed, etc. There were even […]

Machinery protection systems (MPSs) and SIL safety levels – The API 670 perspective

Operational safety within the process industries has always been a priority. As the process sector moved into the computer age, new issues arose as manufacturing plants converted to computer-based control systems (replacing their aging electrical, pneumatic, and electronic controls). Accordingly, the process sector developed a variety of tools to address these problems, but safety performance […]

Bridging the gap between machinery protection and condition monitoring

Different goals, similar instrumentation A machinery protection system and a condition monitoring system fundamentally fulfill different goals. According to the American Petroleum Institute’s standard for machinery protection systems, API Standard 670, 5th edition (Annex N Condition Monitoring): The goal of a machinery protection system (MPS) is injury prevention, the avoidance of damage to a machine […]

VM600Mk2 “one module does it all” concept explained

Like the VM600, the new VM600Mk2 system is designed as a centralized system, with a well-thought-out modular structure allowing smart function combinations that enable complex systems to be built from a minimum number of modules. From system configuration to retrofit, the VM600Mk2 "one module does it all" concept focuses on reducing the total cost of […]

General API 670 requirements for machinery protection systems

The American Petroleum Institute’s standard for machinery protection systems (API Standard 670) is a widely recognised industry standard, used actively by regulators and operators around the globe. The API 670 standard describes the minimum requirements for a machinery protection system (MPS) that measures shaft and casing vibration, shaft position, shaft rotational speed, piston rod drop, […]
