Electronic pressure switch with display Model PSD-4 WIKA data sheet PE 81.86 for further approvals, see page 8 @ IO-Link Applications■ Machine tools ■ Hydraulics and pneumatics ■ Special machine building ■ Food and pharmaceutical industry ■ Advanced condition monitoring via IO-Link ■ Higher flexibility, lower inventory ■ Easy integration combined with good readability Electronic pressure switch, model PSD-4Description The PSD-4 electronic pressure switch is the universal solution for industrial automation tasks - also in hygienic applications and under harsh conditions. Due to an accuracy of < ±0.5 % and minimal long-term drift, it permanently ensures an accurate representation of the process pressure for more than 100 million load cycles. The pressure switch is available with a digital output signal as well as a switchable and scalable analogue output. In addition, it can also be easily monitored via the self-diagnostics. Advanced condition monitoring via IO-Link Condition data and the diagnostic functions allow consistent monitoring. Whether it is defective or whether the pressure or temperature values are above or below the specifications is displayed directly in the system. The data also allow conclusions to be drawn about changing process conditions. Additional information helps to check the loading. Higher flexibility, lower inventory Low stocking costs due to fewer variants: With the scalable analogue output, the measuring range can be restricted in a ratio of 5:1. In addition, the output signal can be configured specifically for the application. Thus the PSD-4 can be used flexibly. Easy integration combined with good readability Thanks to the large 14-segment display and red digits, pressure values are easy to read, even in bright environments. In addition, the display's content can be turned through 180° and the case through > 300°. Fast parameterisation via 3-buttons The PSD-4 can be set via 3-button operation. Display and menu offer intuitive navigation in accordance with VDMA specification 24574-1. This speeds up parameterisation and reduces the installation effort.
