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 WIKA GLS-1000 float switch has been developed for monitoring the levels of liquids. It combines the advantages of the proven and robust float-based measuring principle with modern digital switching technology with PNP and NPN output signals. The WIKA GLS-1000 float switch is suitable for a multitude of media, such as for example, oil, water, diesel and refrigerants. A permanent magnet built into the float, through its magnetic field, activates the semiconductor sensors built into the guide tube. The switching operation is contact-free and free from wear. Since no mechanical switching process is triggered, the sensor offers an unlimited number of switching cycles. Depending on customer wishes, the switching functions of normally open and normally closed can be realised as PNP or NPN outputs for the defined switch position.
