The installation of a sensor element or a corresponding assembly has the advantage that very compact dimensions are possible. However, some points need to be taken into account, which are an additional effort for the customer compared to using a fully adjusted sensor …
Pressure sensor
Which are the available configuration levels for pressure sensors?
| Christian Wirl | PressureThe various possible configuration levels for a pressure measurement solution are not defined conceptually in any standard. At WIKA we have chosen the following terminology: A pressure sensor (also pressure transmitter) delivers a standardised, …
“UL Recognized”, “UL Listing” – What’s the difference?
| Jens Bargon | Know-howThe “UL approval” is an important and well-known product approval. That there are different approvals for “UL” (“Underwriters Laboratories”) is, however, less known. When one talks in general about “UL approval”, in most cases “UL Listing” …
RoHS marking and certificates
| Peter Ottens | Know-howI 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 …
Signal clamping in pressure transmitters
| Michèle Beyer | Know-howIn 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 …
