Integration of pressure sensors into the PLC
Stefan Heusel | Know-howThe 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 …
Connection of an Ex nA digital indicator to an Ex i sensor
Stefan Heusel | Know-howIs 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 …
Characteristics of the display of a digital indicator
Anna Zeitler | Know-howThe characteristics of the display are an important selection criterion when deciding on a digital indicator. Here, there are different points that must be considered: 1. The number of segments This concerns the segments used to display the numbers. The …
14-segment-display vs. 7-segment-display: Advantages/comparison with regard to readability in electronic pressure switches
Jürgen Reiser | GeneralDurable, robust and easy-to-read are the requirements for the display of industrial electronic pressure switches. State-of-the-art is typically a 4-digit 7-segment LED display in red. However, in particular the display of letters on the seven segments is only possible …
