Cryogenic isolators, water isolators and vacuum isolators provide electrical isolation of system components that operate within a common environment. They can also be used to provide a conduit to introduce gases or liquids into hermetic systems.
Electrical isolators, sometimes referred to as “breaks” or “envelopes”, consist of metal sleeves brazed to each end of an insulating ceramic tube. Cryogenic isolators are used to introduce cryogenic fluids into a system and to provide electrical isolation of line components. Water isolators are used to introduce water or other fluids into a system and to provide electrical isolation of line components. Vacuum isolators are used to provide an electrical break between the vacuum system and other external components.
Ceramaseal® isolators from CeramTec are made from high-purity alumina ceramics (90% or better). The metal hardware is generally a controlled-expansion nickel-iron alloy, 304 stainless steel or copper. All materials and braze alloys used are chosen for their specific characteristics and ability to maintain the integrity of the seals for use in demanding applications and environments. The assemblies are brazed together using copper, gold-copper or silver-copper alloys.
CeramTec uses advanced techniques and methods to control and monitor critical processes, including 100 percent helium leak testing and x-ray measurements for metalization control. Standard installation mountings for Ceramaseal® isolators include:
