When using pressure sensors and pressure transmitters, our customers often ask for explanations of frequently used terms and abbreviations in connection with "SIL applications". SIL – which means Safety Integrity Level, and PL, which means Performance Level, are …
In my last article, the design of a submersible pressure transmitter / level probe - Part 1, I was explaining the design of a submersible pressure transmitter, beginning with the measuring cell and its electronics. Specifically with respect to the media resistance …
How does the IO-Link communication interface of WIKA's pressure switch PSD-30 actually work? IO-Link is a point-to-point connection (i.e. not a new field bus) between sensor/actuator and a field bus master such as a PLC. The supply of the field device (pin 1 and …
The field of application or the suitability of a pressure sensor for a hazardous area is designated by the marking on the device. As a matter of principle, intrinsically safe pressure sensors marked Ex ia can be used in zone 0 (the "most dangerous" area), whereby …
As soon as a preset pressure is reached, an electronic pressure switch opens or closes a corresponding switch contact. There are various designs of electronic pressure switches which are used in a multitude of industrial and technical processes. Particularly in machine …
