Abstract:

A gas detector having a sealed sensor assembly is only exposed to the ambient atmosphere when the detector is to be placed in the service. The detector is placed in the service by removing an elongated planar adhesive backed sealing member. The gas sensor also incorporates a replaceable biomemetic sensing material which is carried within a housing within the detector. The housing contains an internal region wherein the gas sensing material is located. The internal region is sealed where the housing is attached to a printed circuit board on one hand and by the removable sealing planar member on the other hand so as to protect the gas sensitive material from contamination or exposure to the atmosphere until the unit is placed into service.
