EpRox probes measure even at very low oxygen partial pressure. The gas to be investigated is heated up and catalytically decomposed. After reaction the oxygen content is measured at equilibrium and converted.
EpRox1000-FL for FLOAT – Tin Bath
To avoid oxidation of the liquid tin in tin baths of float plants what would cause glass defects it is important to analyse and control the atmosphere in the tin bath. With the EpRox1000-FL up to 6 selected measuring points per measuring system along the tin bath can be monitored with just one probe.
The dewpoint temperature – based on an equilibrium of oxygen, hydrogen and water steam in the tin bath atmosphere – is calculated after measuring the oxygen content in the atmosphere. Also a HORN® created key figure of the atmosphere based on the tin, oxygen and tin oxide is defined. This gives the controller a quick and scientifically sound statement about the overall state of the atmosphere and its effect on the tin bath.
The EpRox system is available as a stand-alone as well as add-on system to a HORN® SCADA system.
