Description
(5) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ТЕМПЕРАТУРЫ ГАЗОВОГО ПОТОКА(5) DEVICE FOR MEASURING THE GAS FLOW TEMPERATURE
1one
Изобретейие относитс к термомет рии и может быть использовано при измерении температуры воздуха или газов газотурбинных двигателей.The invention relates to thermometry and can be used to measure the temperature of air or gases of gas turbine engines.
По основному авт. СЁ. № 8879 3 известно устройство дл измерени температуры газового потока, содержащее т.ермодатчик с ; усилителем, выход которого подключен к входу сумматора , через дифференцирующий блок- ю к входу блока перемножени и через первый фильтр-преобразователь - к входу вычислител , датчик давлени с усилителем, соединенный через второй фильтр-преобразователь с вторым ts входом вычислител , выход которого подключен к второму входу блока перемножени , соединенного свторым входом сумматора Р According to the main author. Here. No. 8879 3, a device is known for measuring the temperature of a gas stream comprising a temperature sensor with; the amplifier, whose output is connected to the input of the adder, through a differentiation unit to the input of the multiplication unit and through the first filter converter to the input of the calculator, a pressure sensor with an amplifier connected through a second filter converter to the second ts input of the calculator, the output of which is connected to the second input of the multiplication unit connected to the second input of the adder P
Однако это устройство имеет погрешность , обусловленную отсутствием коррекции по посто нной времени датчика дав ени .However, this device has an error due to the lack of correction for the constant time of the pressure sensor.
Целью изобретени вл етс повышение точности измерени .The aim of the invention is to improve the measurement accuracy.
Поставленна цель достигаетс тем, что в устройство дл измерени температуры газового потока дополнительно введены соединенные последовательно дифференцирующий блок, блок умножени и сумматор, а также задатчик посто нной времени, выход которого соединен с одним из входов дополнительного блока умножени , причем выход датчика давлени с усилителем соединен с входом дополнительного дифференцирующего блока и с вторым входом дополнительного сумматора , а выход последнего соединен с входом второго фильтра-преобразовател .The goal is achieved by adding a series-connected differentiation unit, a multiplication unit and an adder, as well as a constant time setting device, the output of which is connected to one of the inputs of the additional multiplication unit, to the device for measuring the temperature of the gas flow; with the input of the additional differentiating unit and with the second input of the additional adder, and the output of the latter is connected to the input of the second filter converter.
На чертеже приведена блок-схема предлагаемого устройства.The drawing shows a block diagram of the proposed device.
