High Temperature Probes

5-hole probe high temperature pressure

Did you ever want to measure temperatures and pressures at the exit of a combustion chamber?
We have several solutions if you want to use our probes at higher temperatures. These probes are also based on an additive manufacturing process, providing the same advantages as with our other probes.


Details

Metal superalloys can be used at up to 1000 deg C (1800 °F). If higher temperatures are required, ceramics such as silicon nitride (SiN) can be used, capable of temperatures up to 1800 deg C (3250 °F). And as mentioned before, these highly customized solutions are made using additive manufacturing allowing for a high degree of customization.
