Although valves are non-rotating mechanical assets, they can still sustain damaging vibrations and incur other problems. Monitoring their condition is important – particularly on the large valves used in nuclear steam turbine service. In this second and final installment of a 2-part series, we wrap up our discussion by explaining what types of valves are […]

Although valves are non-rotating mechanical assets, they can still sustain damaging vibrations and incur other problems. Monitoring their condition is important – particularly on the large valves used in nuclear steam turbine service. In this 2-part article, we explain what these valves do, why they are monitored, and how they are monitored. Introduction There are […]

Our products are used to monitor and protect the largest machines and operations on the planet. That’s not hyperbole – that’s fact. In this series of articles, we have examined the world’s largest gas and steam turbines and our role in protecting them. We now conclude this 3-part series with a look at our historic […]

Our products are used to monitor and protect the largest machines and operations on the planet. That’s not hyperbole – that’s fact. In this series of articles, we examine three of the “world’s largest” and what we do to make them safe and reliable. We continue our series here with installment #2 and an examination […]

Our products are used to monitor and protect the largest machines and operations on the planet. That’s not hyperbole – that’s fact. In this series of articles, we examine three of the “world’s largest” and what we do to make them safe and reliable. Here, we showcase the world’s largest gas turbine – the Siemens […]

In a recent customer survey on projects involving vibration system installations, upgrades, and retrofits, we gained insights that we wanted to pass along to you – some surprising, and some not-so-surprising – but all valuable. Introduction In September 2022, we surveyed 17 existing and potential customers with a series of qualitative questions about upgrade projects […]

Thirty years ago, the phrase “islands of automation” was commonplace. It described instrument and control systems that exhibited very poor connectivity and were thus “islands unto themselves.” What little connectivity existed might consist only of analog 4-20mA outputs or discrete signals from relays. Although the phrase may not be as common these days, the ability to properly connect systems to one another remains a concern.

The debate over centralized versus distributed instrumentation architectures has been ongoing for more than 40 years, predating many of those reading this. Nor will it end any time soon. This is unfortunate because it is needless.

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.

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).
