Product Details:

FOXBORO 130K-N4-LLPF is a compact pneumatic indicating controller belonging to FOXBORO 130K series, a high-performance industrial instrumentation built for single-loop field control. This pneumatic controller adopts precision mechanical pneumatic components, assembled inside a sturdy metal housing to withstand vibration, moisture and corrosive atmosphere in heavy industrial sites. The front panel integrates a clear analog dial, showing process variable and setpoint at the same time for operators to read and adjust parameters locally conveniently.

This FOXBORO 130K-N4-LLPF pneumatic controller receives 3~15 psi pneumatic measurement signal from field transmitters that monitor temperature, pressure, flow or liquid level. It calculates PID control output and sends 3~15 psi pneumatic signal to drive valve actuators to realize closed-loop process regulator. It supports bumpless auto-manual transfer; switching between automatic control and manual output adjustment will not cause sudden signal jump, which protects production stability. The unit can accept local setpoint adjustment, and also supports remote pneumatic setpoint input to match different process control requirements.

Without electronic circuit design, this pneumatic controller has excellent anti-electromagnetic interference capability, suitable for explosion hazardous areas where electronic instruments cannot operate safely. The internal mechanical structure is modular, making inspection, disassembly and component replacement simple, cutting maintenance workload and plant downtime. This process regulator is widely used in oil & gas, chemical refining, power generation, pulp and paper industries. It is suitable for new plant construction projects and spare parts replacement for legacy pneumatic control systems. The FOXBORO 130K-N4-LLPF pneumatic controller has been factory calibrated before delivery, maintaining stable and consistent performance for long-term continuous process automation.
