Peak Sensors supplies temperature sensors to many specialised applications. POX, Partial Oxidation is a chemical plant process which uses fuel / air mixture to partially oxidise the gases into other useful products. Carbon Monoxide is the common product. The POX temperature sensor requires some novel design detail to survive the plant and to be safe should failure occur.

POX Process

This process occurs at temperatures around 1200 deg C. It is a very aggressive environment for temperature sensors. Heat, Pressure, Oxygen and Combustion products are present. A number of Probes are typically situated almost within the insulation to give them some protection. As insulation deteriates over the plant life the probes get an even tougher life.… Read more
