Sealed Sensor Assembly Gets A Reliability Boost

What’s the best way to incorporate sensors and sensing electronics into a pressure or vacuum chamber? Traditionally, the answer would have involved a hermetically sealed wire feedthrough. And in applications with complex or numerous electrical connections, well-designed hermetic feedthroughs are still the way to go.

However, there is another lesser-known way to bring sensors and similar electronics into a pressure chamber. Rather than pass sealed wires through through the pressure wall as with a feedthrough, you can instead hermetically seal circuit board assemblies that interface with a sensor. These sealed circuit board assemblies can then protrude directly into the pressure or vacuum chamber.

In the right applications, sealed circuit board assemblies have some persuasive performance and cost benefits. This white paper will examine how Lumasense, a leading provider of condition monitoring systems for power generation and distribution equipment, reaped those benefits.
