Over the years, we at Sandelius have manufactured many different types of high pressure thermocouple assemblies. We maintain a pressure testing set-up capable of performing tests up to 80,000 PSI. Whether you have an existing design or would like to develop a new high pressure thermocouple specification, we would appreciate the opportunity to quote on your requirements.
