The WIKA PSD-30 and PSD-31 pressure switches are currently being phased out, to be replaced with the newly updated PSD-4 pressure switch.
The model PSD-4 pressure switch represents the extensive development of the 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 analog output, in addition to outstanding self-diagnostics, make the PSD-4 an excellent automation solution for industrial machines, hydraulic systems, and pneumatic systems applications.
While the PSD-4 offers new features and functionality, pricing is comparable to that of the PSD-30 and PSD-31. This new pressure transmitter offers customizable features, such as allowing the user to select the switch type and output signal, while offering a 5:1 turndown ratio. Additionally, this transmitter is an economical solution for applications requiring local display with an analog output signal. The PSD-4 provides an upgrade in quality and customizability without negatively affecting budgets.
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.
