These thermocouples are best suited to capture high temperatures. They are predominantly used in industry and machine building because of their high mechanical strength. Since they are sheathed in flame-resistant magnesium oxide, they withstand high pressures, vibration and shocks. In the solder technology, they are used to record time/temperature processes for boards in soldering systems. When selecting these thermocouples, care must be taken to choose units with a low heat capacity, so that the measuring results are not compromised.
