Description:

The ETS 2000 Extraction System constitutes the ET 2000 High-Temperature Probe and the EP 2000 Pump Unit that combine to form an accessory for the zirconium dioxide measuring cell OS 2000 of the OC 2000 oxygen measuring system.
This system is applied in an environment with flue gas temperatures exceeding 300°C or whenever other conditions prevent a probe from being installed directly at the point of measurement. This system is applied in an
environment with flue gas temperatures exceeding 300°C or whenever other
conditions prevent a probe from beinginstalled directly at the point of measurement.
The EP 2000 Pump Unit allows the system to extract a representative flue-gas sample through the temperature stable probe pipe, past the measuring probe, through the pump, and back to the furnace.
All parts of the ET 2000 probe are made in acid proof stainless steel, (AISI 316) except the extraction pipe which is aluminium oxide.
The EP 2000 flue gas extraction pump has been conceived and designed to ensure a long service life, using materials which resist all condensate products found in flue gasses. Vital wearing parts are made from carbon fibres.

Application:

The principal fields of application of the ETS 2000 Extraction System
are in metal melting furnaces, cremation furnaces and other systems
where the oxygen content needs to be determined before the
flue gas is conducted through a heat exchanger, or where flue-gas
cooling is absent.
