92-91 Fireye LENS CAP

Overview

The Fireye 92-91 is a flat, non-magnifying lens cap designed specifically for use with 48PT series infrared flame scanners. Its primary function is to protect the scanner’s sensitive lens assembly from environmental contaminants while maintaining a clear line of sight for flame detection. By shielding the optical components from dust, dirt, and moisture, the cap ensures the scanner operates reliably in demanding industrial combustion environments.

Features

• Flat, non-magnifying design to prevent distortion of the infrared flame signal.
• Constructed to withstand high-temperature industrial settings.
• Direct-fit replacement part for 48PT scanners, ensuring a secure and easy installation.
• Protective barrier that prevents accumulation of soot and debris on the primary scanner lens.

Specifications

• Model Number: 92-91
• Lens Type: Flat (non-magnifying)
• Material: High-quality transparent quartz or heat-resistant glass.
• Compatibility: Fireye 48PT series scanners (e.g., 48PT1, 48PT2).
• Operating Temperature: Designed to match the scanner’s rating, typically up to 200 degree F (94 degree C).

Applications

The 92-91 lens cap is used in industrial and commercial boiler and burner management systems. It is an essential accessory for 48PT infrared scanners monitoring natural gas and oil flames in applications such as oil and gas refining, power generation, pulp and paper mills, and petrochemical plants. It is particularly valuable in environments with high levels of airborne particulates where lens fouling is a concern.
