Vacuum Process Sensors
- Designed for vacuum application temperatures up to 2300 °C
- Available in all standard ANSI calibrations
- Optimum performance in most critical vacuum applications
Vulcan Electric Vacuum Process Line of temperature sensors using the latest seal fitting technologies that can be designed to seal pressures ranging from vacuum up to 30,000 psi (2067 bars) and designed for durability and reliability in high temperature applications to 4200° F (2315° C). Such applications generally involve vacuum, reducing, inert gas, graphite, or contamination atmospheres that challenge the life of the thermocouple. Vulcan’s knowledgeable team design and manufacture vacuum sensor assemblies with a selection of appropriate materials and configurations to maximize the life and reliability of thermocouples in these environments.
