Изобретение относитс  к струйным устройствам , чувствительным к изменению температуры .This invention relates to ink jet devices that are sensitive to changes in temperature.

Известные устройства дл  измерени  температуры газовых потоков, содержащие пневматическую регистрирующую систему и датчик температуры в виде биметаллической пластины , недостаточно точны.The known devices for measuring the temperature of gas streams, which contain a pneumatic recording system and a temperature sensor in the form of a bimetallic plate, are not accurate enough.

Дл  новыщени  точности измерени  в предлагаемом устройстве струйный датчик температуры выполнен в виде сопла из двух материалов с различными коэффициентами теплового расщирени .To improve the measurement accuracy in the proposed device, the jet temperature sensor is made in the form of a nozzle of two materials with different coefficients of thermal expansion.

На чертеже изображена схема описываемого устройства.The drawing shows a diagram of the described device.

Датчик температуры, выполненный в виде тонкостенного сопла 1 из материалов с различными коэффициентами теплового расширени , и сопло 2 сравнени  из материала, нечувствительного к изменению температуры, расположены соосно с входными каналами 3, 4 сопел управлени  пневматической регистрирующей системы 5.A temperature sensor, made in the form of a thin-walled nozzle 1 of materials with different coefficients of thermal expansion, and a comparison nozzle 2 of a material that is insensitive to temperature change, are coaxial with the input channels 3, 4 of the control nozzles of the pneumatic recording system 5.

Устройство работает следующим образом. При изменении температуры потока измен етс  наклон сопла 1 относительно входного канала 3, наклон ж& сопла 2 не измен етс . Разность давлений, возникающа  на входных каналах 3, 4 и пропорциональна  темнературе , регистрируетс  пневматической системой 5.The device works as follows. When the flow temperature changes, the slope of the nozzle 1 changes relative to the inlet channel 3, the slope is & nozzle 2 is unchanged. The pressure difference arising at the input channels 3, 4 and proportional to the temperature is recorded by the pneumatic system 5.
