Zedeyes 3209 PNP/NPN Pressure Switch

The Zedeyes 3209 is an intelligent, high-precision digital pressure switch engineered to integrate real-time pressure measurement, local visual display, signal output, and automated process control into a single compact device. Built around a high-stability silicon piezoresistive pressure sensor, precision low-drift amplifier, and advanced microprocessor, the Model 3209 delivers reliable digital pressure tracking paired with dual switching outputs for automated machinery and safety interlocks.

Featuring a bright 4-digit OLED display, dual NPN/PNP output compatibility, and a intuitive keypad interface, the Zedeyes 3209 allows quick field configuration, adjustable response times, and one-key zero calibration. It is widely utilized across hydraulic control skids, water distribution loops, chemical processing, and automated machinery.
