Measuring tank levels in boiler systems with DELTA-trans
| Jing Lyu | ApplicationsThe fill level in the feed tank of industrial boiler systems is a crucial process parameter to ensure a smooth energy supply of steam or hot water. A manufacturer of such systems uses the model DPGT40 differential pressure gauge from WIKA's DELTA-line product family to …
Monitoring the level in liquid gas tanks with a Cryo Gauge
| Hardy Orzikowski | Level, ProductsIn the past, monitoring the filling level in liquid gas tanks using differential pressure has always been a challenge. This is because the manufacturers of tank equipment had to construct their own measuring systems in order to record the liquid level and the operating …
3 1/2- vs. 4-digit digital indicator – What is a 1/2 digit?
| Anna Zeitler | Know-howBesides 3- and 4-digit digital indicators, there are also 3 1/2-digit indicators available in the market. But what is a 1/2 digit? A full digit can indicate all numbers from “0” to “9”. A 1/2 digit, in contrast, can only display a “1”, a number …
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 …
