摘要： An improved right angle thermocouple provides for constant pressure sensing tip contact achieved by means of a coiled and thus resiliently biased junction wire structure extending from the mounting base, preferably in the form of a circular loop of flattened ribbon shaped dissimilar metallic wires overlapped at a welded sensing tip. This sensing tip is protected by a spring biased protective shield of low thermal conductivity material having a few prongs extending from its open end for contact with the surface to be monitored in a manner that causes little thermal modification that would result in an erroneous temperature reading. The shield member, preferably cylindrical in shape, moves between two stops, one surrounding and protecting the sensing tip from physical damage and the other withdrawing just enough to permit the resilient bias of the sensing tip loop to establish a constant measurement contact pressure. The sensing tip is an unsupported loop of wire terminating in a welded junction of two ribbon elements so coiled as to produce a spring bias establishing the contact pressure of the sensing tip with the surface to be monitored, thereby avoiding temperature errors resulting from either thermal bleedoff from the heat source being sensed or from variations of contact pressure at the sensing tip.

摘要： A renewable, elongated thermocouple probe having a first elongated thermocouple element and a second elongated thermocouple element surrounding the first element. Electrical insulation material is positioned between opposed surfaces of the first and second thermocouple elements to electrically insulate the elements from each other. A temperature sensing tip is provided at one end of the probe by grinding the end of the probe with an abrasive material to provide an electrically conductive connection in the form of metallic particles to define a conduction path between the first and second thermocouple elements and over the insulating material. The opposite end of the probe can be connected with a thermocouple reference junction in a conventional manner.
