Flue gas oxygen (O2) analyzer
25 - 1400°C, MOD-BUS, HART | Model HL303 Fer Strumenti

This analyzer has the unique characteristic that enables the use in process with extremely wide limit of temperature. The probe carries on a real O2 in situ measure with fast response time and there is no flue gas, that circulates inside the probe. The analyzer can be used in process with high particulate content and aggressive atmosphere, like combustion and post combustion chamber of incinerators of domestic and industrial waste.

The analyzer is composed by the probe mod. 4170, electronic unit B770 and Flowmeter box mod. 60 or mod.62

Probe mod.4170

Based on a fully stabilized zirconia element, the probe is provided of a special heater of the zirconia cell that enables the use in process with temperature from 100 to 1400 °C .

The heating element is a thick platinum wire which rises the temperature of the cell to 580 °C . A thermocouple measures the temperature of the probe. If the temperature of the probe due to the combustion rises above 580 °C , the electric power is cut off and the electronic unit compensates the O2 value considering the real temperature of the probe.

The materials used for the construction of the wet parts of the probe are high purity ceramics and platinum.
