3. The multipoint thermometer is installed, when a plurality of armored cables are required to be inserted into the thermometer sleeve at the same time, on the premise that the armored cables are not bundled, the longer the insertion depth is, the larger the friction force between the armored cables and the inner wall of the sleeve is, the mechanical strength of the armored cable body can be reduced along with the longer the insertion depth, the armored cables are easy to bend, and even the armored cables can be blocked in the installation process. If the binding and bundling mode is adopted, although the installation problem is solved, the temperature measuring end is often arranged in the center of the sleeve to cause temperature measuring response lag.
