Description
Известно применение термопар дл измерени уровн жидкост, а также указателей уровн поверхности раздела жидкости и газа при отсутствии к кой-либо разности температур между ними, нричем эти указатели выполиеиы ио схеме равновесного моста, сонротивление одного из плеч которого, нагретое до определенной температуры, охлаждаетс при погружении его в жидкость.It is known to use thermocouples to measure the level of a liquid, as well as indicators of the level of the interface between a liquid and a gas in the absence of any temperature difference between them, but these indicators are valid for an equilibrium bridge circuit, the resistance of one of the arms that is heated to a certain temperature immersing it in a liquid.
Предлагаемое устройство отличаетс от известных устройств того же назначени тем, что измерительное нлечо моста выполнено из двух сопротивлений, одним из которых вл етс термоиара, нагреваема отдельным источником тока. Такое выполнепне устройства увеличивает его чувствительность при измереиии.The proposed device differs from the known devices of the same designation in that the measuring bridge is made of two resistances, one of which is a thermo-spark heated by a separate current source. Such a performance of the device increases its sensitivity during measurement.
На чертеже изображена ириннипиальиа схема устр011ства дл определени уровн поверхности раздела жидкости и газа.The drawing shows an irinnipial diagram of the device for determining the level of the interface between the liquid and the gas.
Здесь:R-нагрузочный реостат-170Here: R-load resistor-170
R и R2-два плеча моста ио 500 Ra-илечо моста30R and R2 are the two arms of the bridge io 500 Ra-ilech bridge 30
R- -нлечо моста30 с термопарой а-Ь,R- is a bridge with a thermocouple a-b,
R5-предохранительный реостат в цепи гальванометра.R5-safety resistor in the galvanometer circuit.
Таким образолг схема представл ет мост Уитстона с плечами Ri, Ra, Rs, R4, в котором рабочей деталью вл етс не сопротивление R--., а термопара а-Ь.Thus, the diagram represents a Wheatstone bridge with Ri, Ra, Rs, R4 shoulders, in which the working part is not a resistance R--., But a thermocouple a-b.
При замыкании контактов k-d на мост иодаетс посто нный ток ог тнестивольтового аккумул тора Е; при этом Rs введен.When the k-d contacts are closed on the bridge, a constant current of the voltage-protective battery E is iodized; while Rs is entered.
Передвижением скольз щего контакта с на реостате Rs-R мосг приводитс в грубое равновесие; Ro выключаетс и дальиейипп корректировкой гальванометр устанавливаетс на нуль.By moving the sliding contact with on the rheostat, the Rs-R mosg is brought into a rough equilibrium; The ro is turned off and the galvanometer is adjusted to zero by the corrected galvanometer.
