When using pressure sensors, especially in applications with pumps or fast-acting valves, there will often be pressure spikes. A pressure spike or pressure pulse denotes a rapid rise or drop in pressure. If the transition is too fast, this can lead to the destruction …

What does maximum operating pressure or working pressure mean with pressure sensors?
| Michèle Beyer | Know-howOur customers like to talk about a maximum operating pressure or working pressure. Unfortunately, these two terms are not defined for pressure sensors, which means that a definitive answer cannot be given. All we can assume is that, by maximum operating pressure or …
Calibration / contamination control with a block and bleed valve
| Larry Mock | Know-howA block and bleed valve can be used to prevent flow of contamination from a device under test (DUT) to a pressure controlling calibrator. This procedure includes “exercising” and purging the DUT and the actual calibration. Your procedure may be different but the …
Calibration / contamination control with a block and bleed valve and coalescing filter
| Larry Mock | Know-howWhen calibrating or testing a gauge or transducer with a pneumatic pressure controller it is important to protect the controller from any liquid contaminants that may be present in the device under test (DUT). A block and bleed valve (BBV) in-line with a coalescing …
Pt100, Pt1000 or NTC – which is the right measuring element?
| Roland Sachs | Know-howEspecially the machine-building industry often asks me which is the right measuring element for them. This is the reason why I want to explain in this article the differences between the most commonly used measuring resistors Pt100, Pt1000 and NTC. I will go into more …
