Digital Pressure Control Switch, 10kPa-100MPa, 4-20mA Output

The SUCH digital pressure control switch combines pressure measurement, digital display, and electronic switching for industrial pressure monitoring and control. It covers measuring ranges from 10 kPa to 100 MPa and uses a silicon piezoresistive sensor to measure fluid pressure. The device provides a 4–20 mA analog output and two switch outputs for monitoring and control applications. A 4-digit OLED display shows pressure readings in real time, while available NPN/PNP switching configurations support integration with compatible control systems. Typical applications include hydraulic equipment, fluid pressure monitoring, and industrial automation.

Note: This digital pressure control switch monitors system pressure, triggers switching outputs, and transmits pressure readings through a 4–20 mA signal.
