Fiber Optic Lance

Product catalog summary
Product Overview: The Fiber Optic Lances by BFI Automation are designed to extend the application range of flame monitoring systems. They are highly resistant to temperature and vibration, making them suitable for challenging environments where electronic probes are difficult to install or cool.
Specifications: The lances use high-quality quartz fibers with a transmission spectrum from ultraviolet to far infrared, compatible with semiconductor sensors. The fiber optic cable is robust, featuring stainless steel cladding and a silicone jacket, ensuring water and dust tightness, acid resistance, and temperature stability. The probe can withstand ambient temperatures up to +600 °C, with optical fiber lengths tailored to specific systems, not exceeding 20 meters.
Design: Fiber Optic Lances are customizable, combining rigid and flexible sections for specific solutions. Rigid sections are used for fastening or air purging/cooling, while flexible sections allow easy maintenance. Key components include a cooling air connection, customer-specific flange, guide tube sections, scanner connection, purge air connection, and a sensor head with a lens.
Applications: Ideal for high-temperature, vibration-prone, or space-constrained environments, such as long burner designs and tilting burners. The lances enhance flame intensity detection and external light safety in multi-burner systems. For tilting burners, the sensor head is fixed to maintain a consistent viewing position, with purging and cooling air preventing overheating and residue buildup.
Technical Data: The spectral transmission range is 190 to 1200 nm (UV) and 300 to 2450 nm (IR). The ambient temperature range is -40 °C to +600 °C. The flange connection follows ISO 228 G1 standards, with a bundle diameter of approximately 17 mm. The guide tube diameter is 33.7 mm, with a bending radius greater than 100 mm. Both purge and cooling air connections are ½", requiring 7 m³/h of air.

PRODUCT INFORMATION PART-NO. 6590-9020-01 Fiber Optic Lance Applications •h igh temperatures at the viewing position • in case of strong vibrations at the viewing position • space problems at the viewing position • tilting burners The Fiber Optic Lances are an extension of the application range of our flame monitoring systems. They are characterized by their high temperature and vibration resistant and their robust design. This makes them ideal for applications where the installation or cooling of an electronic probe is difficult or impossible. High-quality quartz fibers are used, which with their transmission spectra from the ultraviolet to the visible to the far infrared range are optimally matched to the semiconductor sensors of the flame sensor. This makes it possible to use it in different emission limits of flame radiation and thus an application for all types of fuel. The glass fibers are integrated into a flexible, robust cable with stainless steel cladding and silicone jacket. The fiber optic cable is thus characterized by water and dust tightness, acid resistance and temperature stability. Technical changes reserved. The probe is equipped with optics that project light with a viewing angle of 2.7° or 6° onto a fiber optic cable. The probe has a ambient temperature stability of up to +600 °C. The lengths of the optical fibers depend on the local conditions and are selected for specific systems. The total length should not exceed 20 m.

1 | Design Fiber Optic Lances are developed and manufactured on project- and customer-specific basis. The lance can be assembled from any combination of rigid and flexible sections, which allows for specific and individual solutions. The rigid sections are usually used for fastening or for feeding purging and/or cooling air. Fiber Optic Lances laid in guide tubes are easy to maintain because they can be removed from the system and reinstalled. 1. ½" cooling air connection 2. Flange accor. customer specification 3.

2 | Applications Poorly accessible viewing positions through long burner designs The radiation intensity of the flame monitoring is reduced significantly by long forms of burners. Fiber Optic Lances can be mounted directly at the fuel outlet of such burner design and thus detect the flame radiation from a short distance from the original flame. This increases not only the flame intensity but also the external light safety in multi-burner systems. Tilting burner Especially for tilting burners, the requirement for flame monitoring is very high, as the viewing position is dynamic. Monitoring is...
