Foxboro P0901XT-02 Multi-Variable Transmitter

Product Description

The Foxboro P0901XT‑02 is a versatile intelligent transmitter designed for multi-parameter process measurement, including pressure, differential pressure, flow, and liquid level. It integrates directly into Foxboro Evo and I/A Series systems, supporting HART, FOUNDATION Fieldbus, and PROFIBUS PA protocols for digital communication and remote monitoring.

Constructed from corrosion-resistant alloys such as stainless steel or Hastelloy, the P0901XT‑02 is optimized for extreme industrial conditions, including offshore platforms, chemical plants, and high-vibration installations. It delivers precise 4–20 mA analog output with optional digital overlays and provides extensive self-diagnostics for predictive maintenance and operational reliability.

While some suppliers describe this module as a Process Control Unit (PCU) or Fieldbus termination module, its primary function remains high-precision measurement and control.
