PURPOSE:To maintain sufficient configuration strength against the large dynamic pressure of a high-temperature, high-pressure air flow, by fixing sheath type thermocoules to a thin supporting plates so that they are positioned in parallel with the air flow. CONSTITUTION:A reinforcing body 11 comprising an inverted U-shaped metal plate is fixed to the top end part of a thermocouple attaching shaft 10. A thin supporting plate 12 is fixed to the top end plate of the shaft 10. A plurality of thermocoules are fixed to the supporting plate 12 and a heat sensitive part is protruded into an air flow. The shaft 10 is arranged at the outside of the air flow to be measured and the reinforcing body 11 is arranged in the air flow to be measured, so that the reinforcing body 11 and the supporting plate 12 are in parallel with the air flow. The air flow, which has entered in the reinforcing body 11, is divided by the supporting plate 12 and merged at the downstream side of the reinforcing body 11 so as to flow as a unitary stream. Therefore the flowing resistance is low. |
