Abstract: An optical gas sensing apparatus includes an explosion-rated device electronics enclosure. An explosion-rated sensing enclosure has a light transmitting element to allow light to pass out of and into the sensing enclosure. The sensing enclosure is operably coupled to the explosion-rated device electronics enclosure by a feed-through. In one aspect, an internal volume of the sensing enclosure is less than or equal to about one fiftieth of the volume of the explosion-rated device electronics enclosure. In another aspect, the thickness of the light transmitting element is less than or equal to about 3 millimeters. A light source is disposed within the sensing enclosure and is operably coupled to the device electronics. A detector is disposed within the sensing enclosure and is also operably coupled to the device electronics.

Abstract: An adjustable mount for an optical device in a laser spectroscopy system is provided. The adjustable mount includes body configured to mount to a process and a reflector mount having a feature configured to mount an optical device. An interface between the body and the reflector mount allows relative motion between the reflector mount and the body. At least one alignment device is configured to engage the reflector mount and the body to fix a position of the reflector mount relative to the body. An optical device is removably mounted to the reflector mount independent of the alignment device and is sealed to the reflector mount.
