ifm electronic Pressure Sensor
Model: PN7009
1. General Description
The ifm PN7009 is a programmable electronic pressure sensor designed for industrial applications, particularly for monitoring vacuum and relative pressure. It features a robust stainless steel housing, a high-visibility 4-digit LED display, and a G 1/4 process connection.
This sensor is designed for process control and monitoring, providing two independent switching outputs that can be configured as PNP or NPN. It also supports IO-Link, allowing for advanced diagnostics and remote parameter setting.
Key Features 🎯
- Wide Measuring Range: Capable of measuring both vacuum and positive pressure from -1 to 1 bar.
- Dual Switching Outputs: Two independent, programmable switching outputs (PNP/NPN) for flexible control.
- IO-Link Enabled: Allows for digital communication, remote configuration, and diagnostics.
- Clear Display: Bright 4-digit alphanumeric LED display shows the current pressure.
- Programmable: Set points, reset points, output functions (NO/NC), and display units are all programmable via the pushbuttons.
- Robust Housing: Features a stainless steel housing with an IP65 protection rating.
