With sheathed thermocouples SCT108, the flexible part of the probe is a mineral insulated cable. This cable consists of a stainless steel outer sheath, in which the inner conductors are encased for insulation and compressed into a highly compacted ceramic mass. The outer sheath is made of stainless steel or Ni alloy. The inner conductors are welded together at the measuring end of the sheathed cable to form the ’thermocouple’. In designs where the measuring element is not insulated the sheath is also welded to the thermocouple. Connector cables are connected to the other end of the sheathed Üable, the sheathed cable is hermetically sealed with a sealing compound. The connector wires form the basis for the electrical interface, with cable, a connector or a terminal block then attached to these connector wires. Due to their flexibility and the small diameters in which they are available, sheathed thermocouples can be used in ĺocations that are not easily accessible.
