Abstract:
1. A temperature measuring device comprising: a thermo-well tube; a cable or wire type temperature measuring means which is installed in a thermo-well tube; and pulleys installed at outside of openings formed at both ends of the thermo-well tube, respectively, wherein the temperature measuring means has temperature detecting sensors disposed at an intermediate portion thereof, the temperature detecting sensors are moved axially in the thermo-well tube by applying tension to both ends of the cable or wire type temperature measuring means, the temperature detecting sensors include a pair of temperature sensors which are contained in a tube type junction portion and connected to each other, or a pair of temperature sensors which are respectively contained in each tube type junction portion and connected to each other by a connection portion, and the pulleys are used when the tension is applied to the cable or wire type temperature measuring means.
