专利汇可以提供Temperature sensing assembly专利检索,专利查询,专利分析的服务。并且An electrical temperature sensing assembly for detecting the temperature of a remotely located device, such as a bearing, which is operating in a cooling medium. The sensing assembly includes two releasably connected body members. One of the body members is connected to the apparatus containing the bearing and the other is connected with an electrical conduit. A union joins the two body members so that it is not necessary to rotate one body member relative to the other to remove the temperature sensing assembly from the apparatus. Furthermore, it is not necessary to disconnect the electrical conductor from the temperature probe which is contained within the body members when disassembling the temperature sensing assembly. In one embodiment, a spring encircles the temperature probe so that the probe is resiliently biased into intimate engagement with a bearing race or other device wherein the temperature is to be determined. In another embodiment, the temperature probe is rigidly secured and sealed in the body member and, yet, can be removed from the temperature sensing assembly without disconnecting the electrical circuitry connecting the probe with read-out apparatus.,下面是Temperature sensing assembly专利的具体信息内容。

1. A temperature sensing assembly comprising: a first body member having a first end adapted for connection with apparatus wherein the temperature is to be sensed, a second end and an opening intersecting said ends; a second body member having a first end adapted for connection with a conduit, a second end engaging the second end of said first body member and an opening intersecting the end of said second body member; connection means releasably connecting said body members with said openings in alignment and the second ends of said body members in engagement; an elongate sensing element located in said aligned openings and having a sensing end disposed in said first body member and a second end having an electrical conductor extending therefrom and into the conduit; seal means forming a fluid-tight seal between said sensing element and one of said body members; and, biasing means for exerting a resilient force on said sensing element urging said element relatively toward the apparatus wherein the temperature is to be sensed, said biasing means including a first washer-like member slidingly disposed on said sensing element and engageable with said seal means, a second washer-like member disposed on the sensing portion of said sensing element, and a helical spring encircling said sensing element between and engaging said washer-like members and having an unstressed length greater than the distance between said washer-like members.
2. The sensing assembly of claim 1 wherein said seal means comprises a deformable O-ring having an unstressed inner diameter smaller than said sensing element encircling said sensing element and sealingly engaging the second end of said second body member.
3. A temperature sensing assembly comprising: a first body member having a first end adapted for connection with apparatus wherein the temperature is to be sensed, a second end and an opening intersecting said ends; a second body member having a first end adapted for connection with a conduit, a second end engaging the second end of said first body member and an opening intersecting the ends of said second body member, said second end of said second member having a conical recess encircling said opening; connection means releasably connecting said body members with said openings in alignment and the second ends of said body members in engagement; an elongate sensing element located in said aligned openings and having a sensing end disposed in said first body member and a second end having an electrical conductor extending therefrom and into the conduit; and, seal means forming a fluid-tight seal between said sensing element and one of said body members, said seal means including a deformable frusto-conical seal member encircling said sealing element and mating with the conical recess in said second member, and seal deforming means located on said sensing element and engaging said seal member and first body member whereby said seal member is deformed into sealing engagement with said sensing element and second body member when said connection means is connected.
