Configuration (Non-Explosion-Proof Version)

  • Piezoresistive pressure sensor with stainless steel diaphragm filled with silicone oil

  • Electrical connection options:

    • Plug per EN 175301-803-A (IP65)

    • M12 connector (IP67)

    • Integrated cable (IP67)

    • Quickon fast connection (IP67)

  • Output signal: 4–20 mA or 0–10 V

Configuration (Explosion-Proof Version)

  • Same sensor and housing structure as the standard version

  • Supported electrical connections:

    • Plug per EN 175301-803-A (IP65)

    • M12 connector (IP67)

  • Output signal: 4–20 mA

Mode of Operation

The operating pressure is applied to the stainless steel diaphragm, transmitting force to the internal thin-film resistance bridge. The resulting voltage signal is then amplified and converted into either a 4–20 mA current or a 0–10 V DC voltage output.

The output signal is linearly proportional to the input pressure, allowing for seamless integration into industrial monitoring and control systems.
