I am often asked, “How is a RoHS marking actually carried out?” The quick answer: EU RoHS will, from 22nd July 2017, be visible in the CE marking and the declaration of conformity linked to it. China RoHS conformant instruments carry a green logo. Non-conformant …
In certain applications, the current or voltage signal of a pressure transmitter must not exceed and/or drop below a critical value. This can be ensured with the aid of so-called signal limiting. If the pressure on a pressure transmitter lies within the nominal …
When pressure sensors come into contact with hydrogen, this often results in difficulties. Unfortunately, I very often notice in my job that our customers are not aware of this prior to use. This is why they often do not even tell us that their medium contains …
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 …
