Sight Glass Extreme Pressure Test

See what happens when a sight glass at 3,300 psi is struck with a projectile. This video shows an actual pressure-impact test on an L.J. Star Metaglas sight window. A sight glass is the weakest link in a chemical processing system, and when it fails under pressure it is extremely dangerous. Fortunately, there is a way to give glass amazing strength.

Are you certain about uncertainties?

Dr. Gooddata, therefore, recommends that we largely abandon the term “bias.” Instead, we will use the terms “systematic error” and “systematic uncertainty.” Systematic error is the actual error that exists between a measurement and the true value with zero random errors. Systematic uncertainty is taken to mean the estimate of the systematic error’s limits that we could expect with some confidence.
