Eurox oxygen sensors DiRox1500-elpro

The oxygen sensor DiRox1500-elpro measures oxygen content in exhaust gas, thereby helping to increase the efficiency of the furnace. It is specially designed for application at high temperature in regenerative furnaces in hollow glass or flat glass production where a short reaction time is required due to atmosphere changes during reversal of the firing-side.

Advantages at a glance:

Increased furnace efficiency
high temperature oxygen sensor with unique electrodes attached by spring forces up to 1500 °C
fast reaction at changing atmosphere
long lifetime due to the patented active ceramic diffusion block and the particular electrode protection (elpro)
fast and safe installation within 2 hours by the EUROX Holding Device, flexible and adaptable to all furnace geometries
The sensor DiRox1500-elpro consists of a monolithic zirconium (ZrO2) tube, which is gas-tight and enables fast and safe installation. Attached to the zirconium tube are the solid, inner and outer electrodes, made of a special chemical resistant platinum alloy. Both electrodes are constantly pressed against the zirconium tube by compressive spring force, thereby allowing continuous operation. In addition, this measuring cell can operate in reduced atmospheres of up to approx. 1500 °C and in spite of any chemical attacks.

This measuring cell is installed in a protection tube, which has a measuring hole on the tip and additional side bores as inlet for the measuring gas to assure a fast reaction without any mechanical gas extraction.

The outer platinum electrode is separated from the measuring gas by a permeable, patented active ceramic diffusion block and special electrode protection (elpro) developed by EUROX. This offers full protection for the measuring cell against attacks by harmful components of the exhaust gases.

The DiRox1500-elpro sensor is optimized for atmosphere control of regenerative operated glass melting furnaces with alternating firing-sides and changing atmospheres e.g. preheated combustion air and furnace exhaust gases.

 

 

Eurox extractive oxygen sensor EpRox900-FH

The heated, extractive Oxygen Sensor is based on a Zirconia cell and is measuring the real O2 content of Fuel gas - / Air – Premixes by an “ideal, stoichiometric combustion”  i.e. the measured oxygen content equals the flue gas after an “ideal burner” as well. Note: All of the free O2- content in the measuring gas is reacting with all oxidable components until equilibrium and always the free remaining oxygen content is indicated.

Advantages at a glance:

exclusive high operating temperature of 900 °C  of the Zirconium cell (common cells operate up to 750 °C only) warrants a complete and fast catalytic transformation of the gas-air-premixes
“elpro”  EUROX Electrode Protection: electrode protected by the patented active ceramic diffusion block
high cell stability and chemical resistance due to massive non-aging platinum alloy electrodes ( ! no Pt-pastes ! )
reliable electrode contacts by spring forces in an unique way
shortest response times (t95) of some 30 Seconds only (Dew meters: t 95 = ± 2 h)
elaborated stabilized measuring gas flow even at varying flow resistances
low flow sensitivity: a deviation of ± 5 l/h (max. ± 10 l/h) at recommended  30 l/h measuring gas flow leads only to comparable minor influence
rugged heating coil, vastly overzized components, low voltage heating, PID-controlled
no sooting at reducing atmospheres even over long times
high capacity, low dead space filter with high separtion efficiency

 

Eurox extractive oxygen sensor EpRox900-FL

The heated, extractive Oxygen Sensor is based on a Zirconia cell and measures the real O2 content of protective gases even at highest reducing atmospheres. Note: all of the free O2- content in the measuring gas will react with all oxidable components until equilibrium and always the free remaining oxygen content is indicated.

Advantages at a glance:

exclusive high operating temperature of 900 °C  of the Zirconium cell (common cells operate up to 750 °C only) warrants a complete and fast catalytic reaction
