Product Description
Foxboro 43AP-FA42CPC Pneumatic Indicating Controller
Product Overview
- The Foxboro 43AP-FA42CPC is a Pneumatic Indicating Controller from the 43AP series, manufactured by Foxboro, now part of Schneider Electric. This versatile instrument controls process variables such as pressure, temperature, flow, and level by detecting the difference between a process measurement and its setpoint, producing a proportional pneumatic output signal. It is used in industrial applications, including oil and gas, chemical processing, and power generation, for reliable process control in demanding environments.
