Product Details:

FOXBORO 130MN4 is a panel mount pneumatic indicating controller from the classic 130M series, a high precision industrial instrumentation built for single-loop closed-loop control. This pneumatic controller is assembled with finely machined pneumatic mechanical components and housed in a solid metal casing, protecting internal parts from vibration, dust and mild corrosion in heavy industrial environments. The front dial clearly displays both process variable and setpoint value, allowing field operators to observe real-time operating status and adjust setpoints directly on the unit.

This FOXBORO 130MN4 pneumatic controller receives standard 3~15 psi pneumatic measurement signal from field transmitters which detect temperature, pressure, flow or liquid level. It processes the signal via built-in PID algorithm and outputs 3~15 psi pneumatic signal to drive pneumatic valve actuators, forming a complete closed-loop field control system. It has bumpless auto-manual transfer function. Operators can switch between automatic control mode and manual output mode without sudden output jump, avoiding disturbance to continuous production process. The unit supports local setpoint adjustment and can also accept remote pneumatic setpoint input according to different system configuration requirements.

Without electronic circuit boards, this pneumatic controller has strong resistance to electromagnetic interference. It is a reliable choice for explosion hazardous areas where electronic instruments cannot work safely. The internal modular mechanical structure simplifies routine inspection, disassembly and component replacement, effectively reducing maintenance workload and plant downtime. This process regulator is widely applied in oil & gas, chemical refining, power generation, pulp and paper industries. It can be used for new automation project construction, and also serves as spare parts to replace aging pneumatic control equipment on site. Every FOXBORO 130MN4 pneumatic controller is fully calibrated before delivery to guarantee consistent and stable long-term performance for process automation.
