WIKA PSD-4 Electronic flow switch

Description

Leading in design and functionality
The model PSD-4 pressure switch represents the extensive further development of the PSD-30 pressure switch, itself already awarded with the “iF product design award” for its outstanding functionality. A high accuracy of 0.5 %, freely configurable output signals (PNP/NPN, 4 … 20 mA/0 … 10 V), the 5:1 scalability of the analogue output, in addition to outstanding self-diagnostics, make the PSD-4 an excellent automation solution.

Customised installation
The installation of the PSD-4 can be flexibly adapted to the individual mounting situation. Due to the almost unlimited rotation of the digital display and case by more than 300°, the digital display can be adjusted independently of the electrical connection. The digital display can thus always be aligned to face the operator, and the M12 x 1 connection positioned to suit the desired cable routing.

High quality
During development of the WIKA switch family a high value was placed on a robust design and the selection of appropriate materials suited to machine-building applications. For this reason the case and the threaded connection of the electrical connector are made from stainless steel. Overwinding or tearing off the connector is therefore virtually impossible.

IO-Link 1.1
With the optional output signal in accordance with the IO-Link communication standard, the PSD-4 allows a fast integration into modern automation systems. IO-Link offers simpler and faster installation, parameterisation and higher functionality for the PSD-4.
