The construction of a traditional current loop for the capture of pressure sensor signals has its pitfalls – especially when not only a signal must be transmitted to the PLC, but also a local indicator has to be integrated. Let's have a look at the example of a …
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 …
Our 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 …
A 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 …
When 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 …
