The WIKA PSD-4 is an electronic pressure switch with integrated digital display, designed for industrial automation and pressure monitoring tasks. It combines precise pressure detection with configurable outputs and self-diagnostics, making it ideal for machine tools, hydraulic/pneumatic systems, and automated process control.
Typical Applications:
⢠Industrial automation and special machine building
⢠Pressure control in hydraulics and pneumatics
⢠Food and pharmaceutical industry systems
⢠Pump and compressor monitoring
⢠General process control requiring display and switch outputs
Not Recommended For:
⢠Extremely simple ON/OFF pressure indication without control needs (use simpler switches)
⢠Applications requiring only analog pressure transmitters
⢠Identify required pressure range and output type for your system
⢠Verify need for IO-Link communication for integration into automation
⢠Determine switch configuration needed (single/double setpoints, hysteresis, window)
⢠Choose mounting orientation ā display and housing can be rotated for optimal viewing
⢠High Accuracy & Stability: < ±0.5 % of span with minimal long-term drift for reliable monitoring.
⢠Digital Display: Large, easy-to-read pressure value and status indicator ā rotatable 300° for operator visibility.
⢠Configurable Outputs: Flexible switching and scalable analogue output options (PNP/NPN, 4-20 mA, 0-10 V).
⢠Fast Parameterisation: Intuitive 3-button interface for quick setup without complex tools.
⢠Advanced Integration: Optional IO-Link enhances diagnostics and automation communication.
⢠Robust Design: Suitable for harsh industrial conditions with long service life (>100 million cycles).
Q: What outputs are available on the PSD-4?
A: It supports configurable switching outputs (PNP/NPN) and scalable analogue outputs (4-20 mA / 0-10 V).
Q: Can the PSD-4 be integrated into modern automation systems?
A: Yes ā with optional IO-Link 1.1 communication for parameterisation and diagnostic data.
Q: How is the display positioned?
A: The display and casing can be rotated independently over roughly 300°, ensuring readability in most installations.
Q: Is the PSD-4 suitable for hygienic or food-industry use?
A: Yes ā its design supports hygienic applications in addition to general automation.
