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 …
Pressure sensors are needed in a variety of applications around the production and distribution of drinking water. As soon as a pressure sensor comes into contact with drinking water, one wonders, as a user, whether this is allowed. After all, for food and also …
Is it possible to connect a non-incendive Ex nA digital indicator to an intrinsically safe Ex i sensor in hazardous areas? Very often, signals from pressure sensors that do not have a built-in digital indicator for the measured value are connected to external digital …
In my last article I introduced you to how the “basic” proof of intrinsic safety can be provided for instruments and pressure sensors approved to ATEX in Europe. Each installer or operator must ensure that the employees in the plant are not endangered and …
