A closed path infrared sensor includes an enclosure, a first energy source within the enclosure, at least a second energy source within the enclosure, at least one detector system within the enclosure and a mirror system external to the enclosure and spaced from the enclosure. The mirror system reflects energy from the first energy source to the at least one detector system via a first analytical path and reflects energy from the second energy source to the at least one detector system via a second analytical path. Each of the first analytical path and the second analytical path are less than two feet in length.

Infrared sensor with multiple sources for gas measurement

A connector includes a first housing section having a plurality of electrically conductive contacts therein. The connector also includes a second housing section including a plurality of electrically conductive contacts that can form an electrical connection with the contacts of the first housing section. The first housing section and the second housing section are removably connectable and are capable of forming an explosion proof or flame proof housing when connected. The contacts of at least one of the second housing section and the first housing section are movable relative to their respective housing section to align the contacts of the second housing and the contacts of the first housing section during connection of the second housing section to the first housing section. Electrically conductive connection between the contacts of the first housing section and the contacts of the second housing section occurs during connection such that when connection between the contacts of the first housing section and the contacts of the second housing section occurs, the first housing section and the second housing section are in sufficient connection to form an explosion proof housing.

Connectors, instrument assemblies and methods of connecting or disconnecting electrical connections under power

A method of communicating information from a sensor includes the step of modulating the emission of energy from an energy source in a manner that corresponds to information to be transmitted from the sensor through a transmissive section in the sensor housing. Energy from the energy source, which is within the housing of the sensor, also interacts with an analyte in a detectable manner. A sensor for detecting the presence of an analyte in an environment being tested includes a housing, an energy source within the housing, at least one detector within the housing adapted to detect interaction between energy emitted by the energy source and the analyte, a transmissive section in the housing through which energy emitted from the energy source can be transmitted; and a controller within the housing in operative connection with the energy source to modulate emission of energy from the energy source in a manner to communicate information through the transmissive section.

An instrument system includes an instrument assembly having at least one fitting projecting therefrom. The instrument system further includes at least a first housing member including at least one alignment member located therein. The alignment member preferably includes at least one sloped surface which slopes toward at least one seating adapted to seat the at least one fitting of the instrument assembly. The instrument system further includes a second housing member which forms an explosion-proof enclosure with the first housing member to enclose the instrument assembly. The second housing member preferably forms an explosion-proof enclosure with the first housing member via cooperating threading. The instrument assembly can, for example, include electrical components for a combustible gas sensor.
