Description
(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ТЕМПЕРАТУРЫ(54) DEVICE FOR TEMPERATURE MEASUREMENT
1one
Изобретение относитс к термометрии .This invention relates to thermometry.
Известно устройство дл измерени температуры, содержащее дилатометрический датчик, соединенный через упругий элемент с пневмосиловым преобразователем, снабженным мембранным блоком и соплом .A device for measuring temperature is known, comprising a dilatometric sensor connected via an elastic element to a pneumatic force transducer equipped with a membrane unit and a nozzle.
Однако известное устройство не обладает требуемой точностью измерени из-за его недостаточной чувствительности .However, the known device does not have the required measurement accuracy due to its insufficient sensitivity.
Наиболее близким по технической сущности к изобретению вл етс устройство дл измерени температуры, содержащее дилатометрический датчик, соединенный посредством рычага и упругого элемента с пневмосиловым преобразователем, который снабжен мембранным блоком, соплом, соединенным через дроссель с линией питани , а через усилитель - с выходом устройства, камерой отрицательной обратной св зи, соединенной черезThe closest to the technical essence of the invention is a device for measuring temperature, containing a dilatometric sensor connected by means of a lever and an elastic element to a pneumatic force transducer, which is equipped with a membrane unit, a nozzle connected through a choke to the power line, and through an amplifier negative feedback camera connected through
дроссельный делитель с выходом устройства , и переключатель диапазонов измерени , содержащий два элемента, одни выходы которых соединены с задатчиками давлени верхнего и нижнего уровн срабатывани , а вторые ьходы - с выходом устройства, нормально закрытый пневмоконтакт, управл ющий вход которого соединен с выходом первого элемента сравнени , a throttle divider with the device output, and a measuring range switch containing two elements, one outputs of which are connected to the upper and lower response pressure setting devices, and the second inputs - to the device output, normally closed pneumatic contact, the control input of which is connected to the output of the first comparison element ,
10 выход с атмосферой, а вход - с входом усилител и через обратный клапан с выходом второго элемента сравнени , и индикатор, соединенный с выходом усилител 21.10 output with the atmosphere, and the input with the input of the amplifier and through a check valve with the output of the second element of the comparison, and the indicator connected to the output of the amplifier 21.

Однако и это устройство не обеспечивает требуемой точности измерени во всем рабочем диапазоне из-за того, что второй диапазон измерени больше первого, а нижний предел However, this device does not provide the required measurement accuracy over the entire working range due to the fact that the second measurement range is greater than the first, and the lower limit
