As 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 simplify the use of pressure switches by standardising menu structure, operation and display.
This means that the most important objective was to make the use of all pressure switches as easy as possible for the user, independent of the specific manufacturer. This is why, with the support from customer, the most important terms and parameters were described and harmonized by the committee, thus defining an intuitive and operator-friendly operator guidance with three keys.
If you like, you can see the result of this work – a easy and self-explanatory 3-key control without any tools – on the WIKA pressure switch PSD-30. Incidentally, WIKA’s pressure switch PSD-30 won the coveted iF Product Design Award for its clear design. Further interesting details on the PSD-30 can be found at the WIKA website, and information on the VDMA specification sheets at VDMA website.
