Abstract
An extended resistance temperature sensor formed of a plurality of lengths of pre-insulated resistance temperature detector (RTD) wire. The RTD wire is either unheated, self heated, alternatingly self heated or is heated by means of strands of heater wire integrated with or placed closely adjacent to the RTD wire. The RTD wire itself, or together with the heater wire, is bonded together in one elongated embodiment. Alternatively the RTD wire, or with the heater wire, may be encased in insulated shrink tubing, thin wall metal tubing or both. Connectors are provided at each end of the elongated structure to supply electrical current for heating purposes or to connect the RTD wire to detection circuitry, or both, and the configuration of RTD wire is doubled back on itself to form a U-shaped structure with the connectors adjacent each other. Protective sheaths are provided over the connectors.
