High temperature oxygen probe;

Oxygen combination sensor with built-in type S thermocouple and threaded connection. Applications (examples): The sensor is used, for example, in carburizing plants to control the C-level, in forging furnaces to control the air supply of the gas burners, or in the atmosphere of crematoria. The sensor is not heated. Therefore, a minimum operating temperature of 500 ° C is required. Material Order: Assembly: Connection head form A with M20x1.5 cable gland Pressure range: Ambient pressure up to 2 bar Temperature range: 520 ° C to 1300 ° C Connection: thread G3 / 4 "DIN 228 / thread G1" DIN 228 Thermocouple: 1 x Type S PtRh (10%) - Pt DIN EN 60584-1, Class 1 Protection tube: Ø 17mm Thermowell material: 99.7% Al2O3 Continuous zirconia tube as electrolyte Reference air connection: Ø 6,0 nozzle max 10 liters / hour Purge air connection: Ø 6,0 nozzle max 200 liters / hour Gas electrode: spiral / helix platinum wire Air electrode: spiral platinum wire
