High Pressure Thermocouple TC90

  • High-pressure thermocouple is used for temperature measurement in industrial applications.
  • The thermocouple is suitable for the highest process requirements and enables reliable temperature measurement, for example, in plastics production and processing.
  • Each TC90 is designed and manufactured in accordance with individual customer specifications.
  • These instruments are manufactured using special manufacturing processes and, in order to ensure their quality, specific test arrangements and material tests are applied.
  • This measuring assembly is sealed by means of metal-to-metal sealing, high-pressure threaded connectors or sealing lenses, which have both proven successful over many years.
