Customer Background
An industrial combustion equipment manufacturer is developing a combustion safety monitoring system designed to verify stable flame combustion following ignition and to trigger protective measures in the event of an accidental flameout. The client’s previous solution proved susceptible to ambient light interference during field testing; consequently, they sought to evaluate a detector capable of responding to ultraviolet (UV) radiation while remaining insensitive to visible light.

Testing Approach
The client procured R2868 samples, and their R&D team developed the necessary drive and signal-processing circuitry to conduct validation tests on a laboratory test bench. Key testing objectives included:

Determining the ability to detect ignition and stable combustion states;
Ensuring the output signal changes promptly upon flame extinction;
Verifying that ambient lighting or fluctuations in visible light do not cause false triggers;
Confirming that detection performance meets design requirements across various installation angles and distances.During the testing process, the client configured the operating circuitry according to the device’s datasheet and connected the sensor output to a controller for data recording and analysis.

Test Results
Under the experimental conditions established by the client, the samples successfully responded to the UV radiation emitted by the combustion flame. Furthermore, the control system was able to detect the signal change immediately following flame extinction. No false triggers were observed when laboratory lighting was activated or when visible light conditions were adjusted. Following multiple cycles of ignition, flameout, and repeated testing, the client confirmed that this solution met the functional validation requirements for their prototype phase.

Future Application
With the sample testing successfully completed, the client has incorporated the R2868 into the next phase of their combustion monitoring system design. They plan to further validate the installation positioning, drive circuitry, signal threshold settings, and long-term stability within the full-scale system environment before deciding on mass-market adoption.

Case Summary
This sample validation process enabled the client to confirm the suitability of the R2868 for their specific flame-detection requirements prior to final productization, thereby mitigating the risks associated with premature bulk procurement or the need for extensive system redesign. For similar projects, it is recommended to first utilize samples for circuit integration and laboratory testing, followed by validation at the equipment and field-application levels.
