Wika Electronic Pressure Switch

Product Code: PSD-30

Award-winning functionality and design

The design and outstanding functionality of the PSD-30 received the IF Product Design Award in 2009. The display, with its .35" ( 9 mm) high digits, was designed to be as large as possible and positioned at an angle, so the pressure reading is visible from a distance of at least 10 feet (3 meters). Time-proven and rugged LED technology with 14-segment display is used so alphanumeric messages are much easier to under-stand compared to typical 7-segment displays.

The large, ergonomically designed programming push buttons provide the user with tactile feedback for immediate confirmation that the touch event was registered by the trans-mitter. The user-friendly menu navigation layout meets the new VDMA Standard form for fluid sensors (24574-1, Part 1, pressure switch). The goal of the VDMA is to simplify the use of pressure switches by standardizing menu navigation and display parameters.

Flexible and adaptable

The PSD-30 can be adjusted three different ways to fit specific installation requirements. The display and electrical connection can be rotated independently to maximize visibility while still orienting the electrical connection in the best position for the cable connector. If the transmitter is installed overhead or upside down the display can be electronically rotated 180°.

Quality and reliability

Time tested, proven WIKA thin film and piezoresitive pressure sensor technology is an integral part of the PSD-30 providing the high quality and long term reliability users demand.
