Each thermocouple is fixed to the bimetals. The bimetals spread out in tight contact with the inside wall of the protecting tube at the operating temperature and the pads that thermocouple are fixed are also pressed against the inside wall of the protecting tube.
Features:
- The thermocouple can be inserted to the protecting tube smoothly because bimetals are closed at the normal temperature.
- The bimetals spread out in tight contact with the inside wall of the protecting tube at the operating temperature.
- Easy to be removed as the bimetallic fins are closed.
