Programmable pressure switch with IO-Link and display

| By Chemical Engineering

WIKA Alexander Wiegand

The new model PSD-4-ECO programmable pressure switch (photo) enables pressure monitoring in machines. With IO-Link version 1.1, the instrument — in a space-saving design and with a two-color display — is a flexible automation solution. The plug-and-play principle enables the new pressure switch to be commissioned quickly, either through individual factory pre-configuration or via IO-Link. Its display can be set so that the operator receives on-site information without any prior knowledge about the status of the current pressure or the condition of the instrument. For example, a measured value within the defined pressure range is displayed in green, a measured value outside the limit in red. For the best possible view of the display, the case head can be rotated and the display tilted electronically through 180 deg. The pressure switch is designed for medium temperatures between –40 and 125°C and shock resistant up to 50 g. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
