Sensor assembly requires some very high technology in both sensing technology and packaging to create a robust, small, and accurate system that can survive in a hostile environment. In the past these sensors could be larger and employ gaskets or other mechanical seals. Today with the need for sensors to optimise operation and safety in everything from spacecraft to consumer goods, the requirement for a low cost, low heat input joining method is critical.
These sensors can also involve very sensitive electrical and mechanical transducers along with temperature sensitive parts and seals so sealing them against the elements must be done with a reliable, low heat-input, system; all at low cost.
Laser welding with redENERGY: A Laser weld of quality components is a hermetic seal so that no contaminants can reach the sensors or pressure transducers and the proper reference pressure will always be preserved. Laser welding has very low heat input and can be placed very close to polymer seals, glass-to-metal seals, soldered components, and electronic circuits. Integration of a Laser system into a sensor welding line is simple with minimal control requirements, non-contact, with a very robust process window and almost no consumables or adjustments when compared to micro-tig, resistance welding, or brazing.
