Precision New Genuine Flame Scanner FIREYE 95DSS1E-1 Good Performance for Industrial Equipment

The FIREYE 95DSS1E-1 is a microprocessor-based, integrated flame scanner that combines dual sensing (IR + UV) with an internal flame relay, so it can detect and prove flame presence without requiring a separate remote flame amplifier. In the InSight Type 95 family, the 95DS models are specifically the dual-sensor version, containing both an infrared sensor and an ultraviolet sensor in one housing, which makes it a practical choice for mixed-fuel or challenging burner conditions where relying on a single spectral band can be limiting. 

Unlike traditional flame detection systems that depend mainly on “brightness,” the InSight scanner determines flame presence by monitoring the frequency spectrum and modulation of flame flicker, then selecting a modulation frequency and gain that best separates “real flame” from background radiation and noise. During setup, the scanner selects the modulation frequency that yields the best ON/OFF discrimination; this is a core reason the InSight platform is used in both single-burner and multi-burner applications where false flame discrimination matters. 

The 95DSS1E-1 is the Standard feature level (S1E) variant in a NEMA 4X / IP66 housing, with a 12-pin quarter-turn quick-disconnect, built for pipe-mount installations. The “E” (S1E) designation indicates the CE-oriented contact rating version, which uses a 50 VAC maximum contact rating class for the relay output specification in the Type 95 documentation. 

Key Product Highlights (What it does well in the real world)

In combustion systems, flame detection is both a safety requirement and a reliability lever: stable detection reduces nuisance trips, and good diagnostics shorten commissioning and maintenance time. The 95DSS1E-1 supports this with:

• Integrated internal flame relay with adjustable ON/OFF thresholds, eliminating the need for a separate flame amplifier in many architectures. 

• Dual IR + UV sensing for broader flame signature coverage across fuels and operating states. 

• 4–20 mA analog output for flame signal strength trending and commissioning verification, plus an onboard alphanumeric display and keypad for configuration and troubleshooting. 

• Two selectable internal files (Standard S1) so you can store separate settings for different fuels or firing rates (for example gas vs oil, low fire vs high fire). 

• Electronic self-checking design (no mechanical shutter required), improving reliability and reducing mechanical wear points.

Understanding the Ordering Code: Why “95DSS1E-1” is a specific, useful variant

Fireye’s Type 95 naming is not decorative; it tells you exactly what you’re buying:

• 95DS = dual-sensor scanner containing both IR and UV sensors.

• S1E = Standard feature set, CE-oriented contact rating class (50 VAC). The Standard S1 feature set includes three choices of modulation frequency, adjustable sensor gain, adjustable flame relay thresholds, 4–20 mA output, fault relay, and two programmable files. 

• -1 = NEMA 4X / IP66 housing with 12-pin electrical connector and pipe-mount configuration. 

This matters for engineering and purchasing because it reduces surprises: the -1 version is typically easier to retrofit into standard burner front installations, and the S1E version aligns with CE contact rating expectations where applicable.

Installation and Commissioning Notes (the stuff that prevents nuisance trips)

Because the InSight scanner “decides” flame presence by evaluating the flame’s frequency spectrum, sighting is everything. Fireye recommends mounting so the primary combustion zone is within the scanner’s line of sight, then using the scanner’s LED display feedback to optimize alignment. 

A few practical best practices from the installation guidance:

• Aim the scanner so the line of sight intersects the burner center at a slight angle and sees as much of the primary combustion zone as possible. 

• Keep the view unobstructed; physical hardware such as register blades may need careful trimming (always coordinate with the burner manufacturer).

• Use the recommended heat insulating nipple to isolate the scanner from ground and reduce conducted noise; this is explicitly called out as important due to the microprocessor-based design. 

• Plan purge/cooling air correctly: 4 SCFM is a common baseline, but near the upper temperature limit or with dusty fuels, higher flow may be required. 

These details are the difference between a flame detector that “works on paper” and one that stays stable after months of thermal cycling, soot, and maintenance shortcuts.

Typical Applications and Fit

The dual IR/UV approach is commonly selected for industrial burners where operating conditions vary or where you want stronger discrimination across different combustion regimes. The Type 95 documentation positions IR sensing as well suited to coal and oil (700–1700 nm IR response) and UV sensing as well suited to gas (295–320 nm UV response), and the dual-sensor 95DS combines both. 
That makes the 95DSS1E-1 a strong candidate for multi-fuel burners, process heaters, boilers, ovens, furnaces, incineration systems, and multi-burner combustion chambers where background radiation can confuse simpler detectors.

Conclusion

The FIREYE 95DSS1E-1 is a rugged, integrated dual IR/UV flame scanner designed to deliver reliable flame discrimination, practical diagnostics, and simplified panel integration through an internal flame relay and a 4–20 mA signal output. With a NEMA 4X / IP66 enclosure, 24 VDC power, and a 12-pin quick-disconnect, it fits cleanly into modern burner management panels and retrofit projects—especially where multi-fuel operation or difficult flame signatures make single-band detection risky.
