Description
Изобретение относитс к устройствам дл измерени уровн кнп дих жидкостей при помощи р да последовательно соединенных термопар , гор чие спаи которых в зависимости от того наход тс они в жидкости или в парах создают различную электродвижущую силу.The present invention relates to devices for measuring the level of liquid fluids using a series of thermocouples connected in series, the hot junctions of which, depending on whether they are in a liquid or in pairs, create a different electromotive force.
Предлагаемое устройство отличаетс от известных тем, что шкала измер ющего э. д. с. термопар выполнена подвижной и механически св зана с подвижной системой м.анометра, измер ющего давление пара в котле, с целью устранени погрешностей показаний устройства, в зависимости от абсолютного значени температуры пара, завис щей от давлени в котле.The proposed device differs from the known ones in that the scale measuring e. d. The thermocouples are made mobile and mechanically connected with the mobile system of an meter measuring steam pressure in the boiler in order to eliminate errors in the readings of the device, depending on the absolute value of the steam temperature depending on the pressure in the boiler.
На чертеже изображена схема предлагаемого устройства дл измерени уровн кип щей жидкости в закрытом сосуде.The drawing shows the scheme of the proposed device for measuring the level of boiling liquid in a closed vessel.
Устройство состоит из датчика 1 в виде р да термопар, вставленных в водомерную колонку 2 и включенных последовательно в цепь милливольтметра 3. Колонка соединена двум патрубками с паровод ным коллектором котла, причем нижний (вод ной) патрубок изогнут в виде U-образной трубки с ребрами дл охлаждени воды, поступающей в колонку. Благодар этому температура этой воды практически будет посто нной.The device consists of a sensor 1 in the form of a series of thermocouples inserted into the water column 2 and connected in series to the millivoltmeter 3. The column is connected by two nozzles with a steam-water collector of the boiler, and the lower (water) nozzle is bent in the form of a U-shaped ribs to cool the water entering the column. Due to this, the temperature of this water will practically be constant.
Термопары состо т из элементов, часть которых соприкасаетс с паром, имеющим температуру t (при данном давлении), а друга (нижн ) -с водой, имеющей температуру tz, причем t значительно больше /2При изменении уровн воды количество элементов, подверженны.х действию высокой температуры парового пространства, мен етс , а следовательно, мен етс и электродвижуща сила батареи по формулеThermocouples consist of elements, some of which are in contact with steam having a temperature t (at a given pressure), and another (lower) with water having a temperature tz, with t being much greater / 2When the water level changes, the number of elements exposed to high temperature of the vapor space, the battery's electromotive force varies and, consequently, according to the formula
