Feedthroughs

Feedthroughs are an important component for many temperature measurements when the measured atmosphere needs to be protected.

If the sensors need to be changed frequently, such as for batch elements, feedthroughs with pre-assembled connectors are suitable.

thermo-control feedthroughs are custom-made and built to customer specifications. They have the following features:

  • Gas-tight / vacuum-tight design
  • Feedthrough with thermocouple cables or sheathed cables
  • Assembly with connector
  • Fixed or replaceable cables
