61-6969 Fireye POTENTIOMeter

Overview

The Fireye 61-6969 is a high-precision feedback potentiometer designed for use with Fireye Nexus servomotors, specifically models NX04, NX20, and NX50. This component is essential for providing accurate position feedback to the burner management system, ensuring that air dampers and fuel valves are precisely positioned according to the programmed combustion profile. It is a critical replacement part for maintaining the reliability and safety of industrial and commercial burner control systems.

Features

• Direct coupling to the drive shaft of the servomotor for immediate and accurate position sensing.
• Conductive plastic construction for enhanced durability and long operational life.
• Integrated feedback mechanism that works in conjunction with the drive controller to prevent positioning errors.
• Compact design engineered for seamless fit within the NX series servomotor housing.
• Reliable electrical interface specifically calibrated for Nexus control systems.

Applications

The Fireye 61-6969 is used exclusively within industrial combustion environments where Fireye Nexus systems are installed. It is primarily applied in servomotors that actuate air dampers, gas valves, and oil valves on large-scale burners. By providing real-time feedback on the angular position of these mechanical elements, it allows the controller to maintain optimal fuel-to-air ratios throughout the burner’s firing range. It is commonly found in boiler rooms, power plants, and manufacturing facilities utilizing Nexus-based flame safeguard controls.
