Foxboro 58P5 Pneumatic Controller – Product Description

Description / Overview

The Foxboro 58P5 is a pneumatic controller from the 58P Series, designed for industrial process control using pneumatic signals. It combines precise PID control with rugged construction, ensuring reliable operation in demanding environments. Moreover, it supports proportional, integral (reset), and derivative actions for accurate process variable regulation. Therefore, operators can achieve stable control of pressure, temperature, flow, and level in processes where electronic controllers are impractical or pneumatic systems are standard.
