Product Overview
The Foxboro 58P5 is a high-precision pneumatic proportional band unit engineered for stable and reliable process regulation. Unlike full pneumatic controllers, the 58P5 is dedicated to proportional band (gain) adjustment, enabling precise tuning of control loop responsiveness.
Commonly deployed in legacy Foxboro pneumatic systems, the 58P5 converts a standard pneumatic input signal into a proportional output, ensuring steady process control in applications where pneumatic reliability and intrinsic safety are critical.

Power Generation
Pneumatic regulation of boiler feedwater and steam pressure using mechanical feedback control loops.
Technical FAQ
Q: What is the primary role of the 58P5 in a control loop?
A: The 58P5 acts as the gain-setting element of the loop. Adjusting the proportional band determines how aggressively the final control element (e.g., control valve) responds to changes in the process variable.
Q: Is the 58P5 suitable for outdoor installation?
A: Yes. The ruggedized enclosure supports field mounting, provided the supply air is clean, dry, and instrument-quality to prevent internal orifice contamination.
