Abstract

There is provided a method for assembly of temperature probes. An insertion element or sensor such as a resistance temperature detector is mounted in a receiving cavity and surrounded by sufficient packing to electrically insulate the sensor. A stalk is utilized as a conduit for routing and insulating lead wires through the support casing. The stalk is notched at a point to facilitate the connection of wires threaded through the stalk to the sensor wires and to minimize the inadvertent contact of these wires with the metallic surfaces. The notch in the stalk protects the junction from contact with the metallic sides of the guide walls and protects the junction from mechanical stresses. To further protect the junction of the lead and sensor wires, the sensor is placed adjacent and parallel to the stalk prior to insertion. The stalk and the sensor are inserted simultaneously with the stalk coming to rest before the sensor travel stops, thereby minimizing the stresses to the junction. The stalk is guided and supported by a cavity in the tip casing. A support casing is mated to one end of the tip casing.
