The robust WIKA PSD-30 and WIKA PSD-31 LED display has been designed using 9 mm high characters (the largest possible) and with a slight incline to make reading the pressure as easy as possible from a long way off. A 14-segment display has been used since it represents text very well. The 3-key operation makes simple, intuitive menu navigation possible, with no need for additional assistance. The menu navigation conforms to the latest VDMA standard. The VDMA standard for fluid sensors (24574-1, part 1 – pressure switches) has the aim of simplifying the use of pressure switches by standardising menu navigation and display. The control keys have been designed as large as possible and are arranged ergonomically to ensure fast and easy adjustments. Operation without any additional assistance is made easier through the tactile feedback. Customised installation The installation of the WIKA PSD-30 and WIKA PSD-31 can be flexibly adapted to the individual mounting situation. Due to the almost unlimited rotation of the display and case by more than 300°, the screen can be adjusted independently of the electrical connection. The 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 the 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 With the optional output signal in accordance with the IO-Link communication standard, the PSD-30 and PSD-31 allow a fast integration into modern automation systems. IO-Link offers even faster installation, parameterisation and higher functionality of the PSD-30 and PSD-31.

The SIKA Type J digital pressure gauge is suitable for both stationary and mobile measurement and display of pressure. The SIKA Type J digital pressure gauge can be used as a reference to explain the checking, adjustment and calibration of other pressure measurement devices directly on-site. PC connection and software Many digital pressure gauges have a serial interface port to allow measurement values and stored data to be transferred directly to a PC and documented. An inexpensive measurement data acquisition system can easily be assembled with suitable software and an interface converter. Processes can be readily monitored and analysed using the recorded and visualised measurements, and all data can be exported using standard programs such as Microsoft Excel. Remote control is also possible. Various software packages with extensive recording and display functions, logger and alarm evaluation as well as for calibration are available. Analogue output An electrical output signal enables remote display on a control console or in a control room as well as the connection of external recorders and indicating instruments. Relay output Digital pressure gauges allow limit contacts to be closed even at low pressures. There is no need for high actuation forces for magnetic spring or inductive contacts, which makes it easier to signal critical equipment conditions and perform supplementary control tasks.
