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: Embodiments of the present disclosure provide a safety protection device for Raman spectroscopy detection and a Raman spectroscopy detection system including the safety protection device. The safety protection device includes: a detection cavity including a cavity body, the cavity body having an opening end through which a sample to be detected is allowed to be placed into the detection cavity; and a cover configured to cover and engage the opening end so as to form, together with the detection cavity, an explosion proof container defining a space for receiving the sample to be detected, the detection cavity further includes a detection opening formed in the cavity body such that a Raman detection probe is allowed to be inserted into the space through the detection opening so as to detect the sample.

Abstract: A gas sensor comprises a cavity for containing a gas, means for generating radiation which is transmitted through the cavity and includes one or more wavelengths which is absorbed in use by a gas to be detected; and a detector for detecting radiation which has passed through the cavity. The walls of the cavity are sufficiently reflective to the radiation that the cavity is substantially uniformally illuminated with the radiation.
