GAS SENSORS WITH STRUCTURE TO RESIST SIGNAL LOSSES DUE TO CONDENSATION

摘要

Embodiments of the disclosure relate to capillary controlled gas sensors comprising a top cap assembly, wherein the top cap assembly is operable to reduce the effects of condensation and pressure changes on the effectiveness of the gas sensor. The top cap assembly comprises a capillary controlled gas flow path, a bulk flow control assembly, and a raised boss surrounded by a moat.
