FiNCORE AFiL In-situ Combustion Oxygen Analyzer (Low Temperature)
FiNCORE AFiL in-situ zirconia O2 (and optional COe/pRed) analyzer for low-temperature applications up to 300 °C, with remote transmitter up to 50 m away.
Key Features
- Process (measured gas) temperature up to 300 °C
- O2 0.1–100 %; optional COe/pRed (10–200 ppm H2, 5000 ppm CO)
- FiNCORE sensor with DIN connector; remote transmitter up to 10 m, or 50 m with junction box
- 2 × 4-20 mA NAMUR + RS485 Modbus RTU
- 24 V DC or 115–230 V AC, average 7 W
- Manual or automatic calibration set
Overview
FiNCORE AFi low-temperature in-situ O2 analyzer for process temperatures up to 300 °C with remote monitoring; configurable sensor, filter holder, calibration, display and communications.
Working Principle
A heated zirconium-oxide (ZrO2) sensor, regulated at 600–800 °C by an S-type thermocouple, measures O2 against an air/gas reference according to the Nernst law; an optional channel measures reducing potential (pRed) / unburnt compounds (COe). The probe is mounted on a direct, by-pass or semi-extractive sampling tube inserted into the flue duct.
Applications
Benefits
- Enables burner fuel/air ratio control for combustion efficiency and process safety
- Low-maintenance probe design with fast response
- Repeatability ±0.5 % of full scale; linearity ±2 % of value
