Vacuum-Thermocouples
Pressure range 10-8mbar to 21bar
Our Vacuum-Thermocouples are used mostly in heat treatment furnaces for hardening, sintering or brazing.
Like all thermo-control thermocouple they follow the basic design principles:
- separated, thin wall-thickness, ceramic protection tubes made from high density 99.7% Al2O3
- additional empty protection tube for in-situ controlling measurements
- Form A connection head
- Standard lengths from 400mm to 1600mm
- 4 years warranty for PtRh-Pt type thermocouples 4 Jahre Garantie against drift thermocouple wire damages
- Standard process fitting with a ISO 2861 small flange or Ø22×150 tube
- Custom made process fitting upon request for quote possible
- Vacuum tight and pressure proof until 20bar
- Maximum Helium leak rate of 10-6 mbar L / s
- Optional with certificate of calibration in accordance to AMS 2750
- Optional assembled with connectors and cables
Following process fittings are available on stock:
Built with ISO 2861 small flange

Built with a Ø22 stainless steel tube
Configuration table
| 8 | – | PP | XX | ZZ | – | LLLL | AA |
- PP – pressure range
- 05 vacuum tight and pressure proof up to 5bar
- 10 vacuum tight and pressure proof up to 10bar
- 15 vacuum tight and pressure proof up to 15bar
- 20 vacuum tight and pressure proof up to 20bar
Please note that for pressures above 5bar it is imperative to apply an additional safety feature such as a chain etc. This ha to prevent the thermocouple from being shot out in case of a loose fitting.
