Известно устройство дл  измерени  двум  датчиками температуры и давлени  газа.A device for measuring two temperature and gas pressure sensors is known.

Однако известным устройством температура и давление измер ютс  не в одной и той же точке газового потока, что приводит к значительной ошибке в оценке его параметров.However, with a known device, temperature and pressure are not measured at the same point in the gas stream, which leads to a significant error in the estimation of its parameters.

Цель изобретени  - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.

Дл  достижени  этой цели на трубке полного напора установлен цилиндрический наконечник из термоизолирующего материала, внутрь которого введен гор чий спай термопары .To achieve this goal, a cylindrical tip of a thermally insulating material is installed on the full-pressure tube, into which a hot junction of the thermocouple is inserted.

На чертеже изображено устройство в разрезе .The drawing shows the device in section.

Устройство содержит кожух 1, заборник 2, отверсти  3 дл  протока -воздуха, камеру 4, трубку 5 полного напора, наконечник 6, термопару 7, отверсти  8 дл  выхода воздуха, камеру торможени  9, корпус 10 устройства.The device comprises a casing 1, an intake 2, openings 3 for duct-air, a chamber 4, a full-pressure tube 5, a tip 6, a thermocouple 7, 8 openings for air outlet, a braking chamber 9, a device body 10.

Устройство работает следующим образом.The device works as follows.

Поток воздуха, поступа  в камеру 9, тормозитс . Одновременно измер ютс  его .параметры: температура и давление. Полное давлениеThe flow of air entering chamber 9 slows down. Its parameters are measured simultaneously: temperature and pressure. Total pressure

щую угол нечувствительности к набегающему воздушному потоку «е менее ±30°. Наконечник 6 трубки 5 изготовлен из термоизолирующего мате1риала, например керамики. Внутрь наконечника введен гор чий опай термопары.inertia angle of insensitivity to incoming air flow "e less than ± 30 °. The tip 6 of the tube 5 is made of thermally insulating material, for example, ceramics. A hot opay thermocouple is inserted inside the tip.

Дл  уменьшени  инерционности термопары в наконеч,нике 6 просверлены отверсти  8 дл  выхода воздуха.To reduce the inertia of the thermocouple in the tip, the nick 6 is drilled holes 8 for air to escape.

Предмет изобретени Subject invention

Устройство дл  измерени  температуры и давлени  газа, например, в каналах лопаточных машин, содержащее камеру стабилизации с размещенной в ней трубкой полного напора , отличающеес  тем, что, с целью повыщени  точности измерени , «а трубке полного напора установлен наконечник из термонзолирующего материала, внутрь которого введен гор ч й спай термопары.A device for measuring temperature and gas pressure, for example, in the channels of blade machines, comprising a stabilization chamber with a full head tube placed in it, characterized in that, in order to improve the measurement accuracy, a tip of a thermal-insulating material is installed in the full head tube A hot junction of the thermocouple is introduced.
