Objectives of the VDMA specification sheet for fluid sensors, Part 1 pressure switches
Jürgen Reiser | PressureAs WIKA representative, I have made a contribution to the preparation of the “VDMA Specification Sheet for Fluid Sensors 24574-1 Part 1 Pressure Switches”. What were the objectives of this VDMA committee? Very simple: The objective of the VDMA specification is to …
14-segment-display vs. 7-segment-display: Advantages/comparison with regard to readability in electronic pressure switches
Jürgen Reiser | GeneralDurable, robust and easy-to-read are the requirements for the display of industrial electronic pressure switches. State-of-the-art is typically a 4-digit 7-segment LED display in red. However, in particular the display of letters on the seven segments is only possible …
Connection diagram of PNP and NPN transistor outputs for electronic pressure switches
Jürgen Reiser | GeneralManufacturers of electronic pressure switches often offer both PNP and NPN switching outputs. Here is a brief explanation how the two different outputs should be connected. In principle, both are bipolar transistors in which only the internal arrangement of the pn …
Overview: Is IO-Link the new communication standard?
Jürgen Reiser | PressureIn connection with the electronic pressure switch PSD-30, I often get asked what is IO-Link and how it is defined. IO-Link is a new communication interface in the area of factory automation/ machine building. Leading providers of automation technology have joined …
