| 摘要 |
The invention relates to a sensor (1) for measuring the temperature of gases at the outlet of a gas turbine such as a helicopter turbine. This sensor comprises an insulated housing (3) intended to be placed outside the turbine and containing a temperature sensor (17), at least one thermocouple (6A, 6B, 6C) comprising a cold junction (11A, 11B, 11C) mounted in the insulated housing (3) and a hot junction (9A, 9B, 9C) intended to be placed inside the turbine. A connector (2) supported by the insulated housing (3) makes it possible to electrically connect this sensor to a data-acquisition apparatus capable of being placed at a distance from the sensor itself. The connection between cold joints may be made in series or parallel, inside or outside the insulated housing (3). Said sensor may comprise type N thermocouples and sheaths made of Haynes alloy. |
