Sensor Specifications
| Model | ARCIS-I25 Series and ARCIS-U25 Series |
|---|---|
| Detection Object |
Combustion of hydrocarbons and non-carbonaceous substances (Such as gasoline, alcohol, natural gas, hydrogen, etc.) |
| Detection Principle |
ARCIS-I25 / ARCIS-3I25: Multi-beam IR sensing with temporal and spectral analysis to validate flame. ARCIS-U25 Series: Dual-spectrum fusion, both UV and IR must be detected to confirm flame. Logic processed by STM32G0B1RET6. |
| Spectral Range |
ARCIS-U25: UV: 185 nm ~ 260 nm ARCIS-I25 and Series: IR: 4.48 µm ~ 5.0 µm ARCIS-U25 Series: UV: 185 nm ~ 260 nm IR: 4.48 µm ~ 5.0 µm |
| Output Signal |
Relay Outputs: 2x SPDT, 5A @ 230VAC or 5A @ 30VDC Analog Output (DAC + XTR111): 0~20 mA loop |
| Response Time (Sensor) |
Level I: 6–10s (Fast alarm, non-interference) Level II: 15–18s (Reliable, clean environments) Level III: 22–26s (Reliable in interference) Level IV: 3–4s (Demonstration mode) |
| Logic Judgment |
ARCIS-I25 / ARCIS-3I25: Multibeam IR correlation (IR only) ARCIS-U25 Series: OR Logic: Valid flame when both UV and IR signals are active |
