The same mixture was used for the fabrication of 15 m long continuousthermal detector.  The addition of La2O3 leads to decrease in thermistor constant and activationenergy values, thus giving freedom to fabricate thermal sensors for various temperatureapplications. A 3 m long continuous thermal detector for application in the temperature range275 - 350 oC was fabricated and later coupled to form a continuous unit of 15 m length. ER -
