ABB UR600IR Mod.1000 Uvisor Flame Detection Probe

The ABB UR600IR Mod.1000, also cataloged as the UR600IR Flame Detection Probe, operates as a dedicated hardware component for infrared radiation monitoring and flame quality evaluation within industrial boiler burner management systems (BMS). It monitors infrared flicker frequencies emitted by combustion flames to provide reliable flame disk detection and discrimination.

Hardware Specifications

Backplane Bus & I/O Isolation Profiles

The ABB UR600IR Mod.1000 flame detection probe utilizes optical sensing elements coupled with onboard pre-amplification to optimize signal-to-noise ratios across harsh furnace environments. The unit routes low-frequency flame flicker signals through narrow-band filtering electronics to prevent false discrimination from background thermal radiation and adjacent burner cross-talk. Isolated signal output channels interface with control room control modules (such as Uvisor central units) while integrated internal shielding limits electromagnetic interference along long field cable runs.

Frequently Asked Questions

Q: What primary spectrum does the UR600IR Mod.1000 utilize for flame detection?

A: The UR600IR Mod.1000 measures infrared (IR) flicker radiation emitted by combustion flames, making it suitable for gas, oil, and pulverized coal burners.

Q: How is thermal protection managed for the probe assembly near high-temperature burner fronts?

A: The housing relies on continuous cooling air purge delivered via the mounting assembly to maintain internal electronics within specified ambient operating temperature limits and keep optical elements clean.

Q: Can the UR600IR probe discriminate between target burner flames and background furnace radiation?

A: Yes, onboard electronic filtering analyzes dynamic flame flicker frequencies to distinguish active combustion from static hot refractory background radiation.

Field Installation Guidelines

1. Ensure the burner management system is safely shut down and local power sources are isolated prior to installation.
2. Mount the sight tube and swivelling head securely to the burner wall, verifying an unobstructed line of sight to the flame target zone.
3. Connect continuous, clean, dry purge air to the cooling port before exposing the probe to furnace ambient heat.
4. Terminate signal cables to the rear terminal block using shielded, twisted-pair cabling, anchoring the shield at a single ground point.
5. Tighten all mechanical mounting hardware and threaded connections to ensure minimum 5-thread engagement before re-energizing the flame safety loop.
