    摘要： A housing sensor having a semiconductor element for measuring hydrogen concentration in an insulating fluid in equipment having a mounting flange on the equipment providing access to the interior of the equipment provided with a plurality of bolt receiving openings arranged on the mounting flange in a first pattern which includes a first flange having at least one or more openings and an outer periphery. The sensor also includes a tubular housing support member having one end received in one of the openings, a plurality of bolt receiving apertures arranged in a pattern corresponding to the first pattern within the outer periphery of the first flange. The sensor further includes at least one wire receiving opening extending through the housing body, a cover closing an end of the housing body distal from the one end, a first seal disposed between the first flange and the tubular housing support member, a second seal disposed on the first flange for engaging the mounting flange.

    摘要： The invention provides a sensor assembly for a sensor having a semiconductor element for measuring hydrogen concentration in an insulating fluid in electric power generation, transmission, and distribution equipment having a temperature well that has a tubular portion extending into the equipment providing access to the interior of the equipment, the temperature well having a movable valve at an end of the tubular portion. The tubular portion includes a first flange, a tubular housing member attached to the first flange having one end adapted to be telescopically received in the temperature well. The tubular portion further includes a housing body having one end thereof connected to the tubular housing member having a substantially uniform cross section extending from the tubular housing member wherein at least one wire receiving opening extends through the housing body. The tubular portion also includes a cover closing an end of the housing body distal from the one end, a first seal disposed between the tubular housing member and the tubular portion of the temperature well for blocking the flow of insulating fluid in the space between the housing member and the temperature well wherein said tubular housing member is long enough so that when fully extended into the temperature well, the tubular housing causes the movable valve to open.
