What is the difference between accuracy and switch point accuracy of electronic pressure switches
| Enrico Bossart | Know-howMany users face difficulties in selecting an electronic pressure switch suitable for their application, due to the differentiation of accuracy and switch point accuracy in many official data sheets. Nevertheless, there is a significant difference between the switch …
Overview: How does the IO-Link work?
| Jürgen Reiser | Know-howHow 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 …
