PSD-4 Pressure Switch

The WIKA PSD-4 pressure switch represents the extensive further development of the award-winning WIKA PSD-30 pressure switch. 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.

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.

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.
