129-189 Fireye Mounting Flange Cover

Overview

The Fireye 129-189 is a mounting flange cover designed specifically for use with oxygen probes in combustion efficiency control systems. It serves as a protective component for the mounting assembly of NXCESO2 and FXCESO2 oxygen probes. While the 35-381-2 mounting flange kit includes the primary flange and screws, the 129-189 cover is an optional accessory that provides an additional layer of protection and completion for the installation, and it must typically be ordered as a separate item.

Features

• Designed to fit perfectly over the O2 probe mounting flange to protect the connection point.
• Compatible with specific high-precision oxygen sensors used in industrial boiler and burner applications.
• Simple installation as a secondary component to the primary mounting kit.
• Durable construction suitable for the high-temperature environments found near flue walls and exhaust stacks.

Specifications

• Part Number: 129-189
• Compatible Probes: Fireye NXCESO2 and FXCESO2
• Associated Kit: 35-381-2 (O2 mounting flange kit)
• Application Type: Oxygen monitoring and combustion efficiency

Applications

The 129-189 mounting flange cover is used in industrial and commercial combustion systems that utilize Fireye Nexus PPC400 or NXF4000 controllers. It is applied at the mounting point where an oxygen probe is inserted into a flue or exhaust stack to monitor combustion gas. It is particularly useful in installations where the probe is mounted on the top of a horizontal flue or where additional protection from environmental factors or physical debris is required for the mounting hardware.
