Product Details:

FOXBORO 130M-N5/ECRB is a panel mount pneumatic indicating controller from the classic 130M series, a premium industrial instrumentation built for single-loop closed-loop field control. This pneumatic controller is assembled with precisely machined pneumatic mechanical components and fitted with a sturdy metal housing, protecting the internal precision parts from vibration, dust and mild corrosive atmosphere in heavy industrial sites. The front panel features a large analog dial that simultaneously shows the real-time process variable and setpoint, allowing field operators to monitor operating status and tune setpoints directly on the unit conveniently.

This FOXBORO 130M-N5/ECRB pneumatic controller receives standard 3~15 psi pneumatic measurement signal from field transmitters that track temperature, pressure, flow or liquid level variables. It processes signals through built-in PID algorithm and outputs 3~15 psi pneumatic signal to drive pneumatic valve actuators, forming a complete closed-loop control circuit. It is equipped with bumpless auto-manual transfer function. Operators can switch freely between automatic control mode and manual output adjustment mode without sudden signal jump, which prevents disturbance and protects continuous production stability. The unit supports local setpoint adjustment and can also accept remote pneumatic setpoint input to match different system configuration requirements. The ECRB option brings enhanced corrosion resistance and improved structural sealing, making it more adaptable to humid and corrosive working environments compared to standard models.

Without electronic circuit boards, this pneumatic controller has strong electromagnetic interference resistance. It is a reliable selection for explosion hazardous locations where electronic instruments cannot operate safely. The internal modular mechanical structure supports simple routine inspection, disassembly and component replacement, effectively cutting maintenance workload and plant downtime. This process regulator is widely used in oil & gas, chemical refining, power generation, pulp and paper industries. It can be deployed for new automation project construction, and also acts as spare parts to replace aging pneumatic control equipment on site. Every FOXBORO 130M-N5/ECRB pneumatic controller is fully calibrated before delivery to maintain consistent and stable long-term performance for process automation.
