Description
Zirconia – O₂
By applying Zirconia (ZrO₂) sensor, changes in Electromotive Force (EMF) due to the ionization reaction among platinum (Pt) electrodes to be converted to the partial pressure (concentration) of oxygen molecules in the flue gas. Most widely accepted O₂ measuring method at any facility, from boiler to CEMS
Features
- Measures ionization reactions based on EMF changes between
platinum (Pt) electrodes using Zirconia (ZrO2) Principle, converted into
oxygen concentrations - Employs a K-type thermocouple for excellent linearity between
temperature and EMF - Maintains measurement accuracy through periodic automatic
self-check cycles - Utilizes an IC with built-in Cold Junction Compensation (CJC)
functionality - Minimizes noise and protects heater lifespan with
Zero-Crossing functionality - Explosion-proof model available (GGA-70-1 Ex.)
