That's right about BP, Ann. One of the gauges was working and indicating that pressure was building. Instead, BP personnel chose to trust a broken gauge that indicated everything was fine. At least, that's what the book on the accident claimed.
Rob, as many have pointed out here, correctly working gauges and meters are only as good as the people reading them--or not reading them. The BP disaster was due at least in part to faulty oversight, i.e., lack of/incorrect monitoring.
Bob from Maine, I suppose one approach to this is to replace the gauge during scheduled downtime. That would mean some gauges would be inoperative during the wait for downtime, but that may be the most efficiently way to deal with this problem.
Rob; One issue about gauges is they are usually direct plumbed into whatever they are monitoring. Thus a broken gauge replacement requires shutting down that entire line and exposing the contents to contamination from outside or vice versa. Putting gauges on shut-offs that permit removal without leaks and making all gauges moveable such that the 'normal' is always in the same orientation. For most processes, gauges are 'trendicators' more than an accurate readout. The percentage of defective gauges is not surprising but what may be surprising is the number of gauges that no longer serve any purpose.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
