Description

Предлагаемый прибор предназначен дл  измерени  высоты уровн  жидкости и основан на применении многослойных проволочных тензометров по авт. св. jY 78644. Чувствительным элементом прибора  вл етс  тензометрическа  мембрана с укрепленными на ней четырьм  многослойными тензометрами, собранными по схеме измерительного моста.The proposed device is designed to measure the height of the liquid level and is based on the use of multilayer wire strain gauges according to ed. St. jY 78644. The sensitive element of the device is a strain gauge membrane with four multi-layered strain gauges mounted on it, assembled according to the measuring bridge design.

На фиг. 1 показана принципиальна  схема прибора; на фиг. 2 - конструктивное его выполнение.FIG. 1 shows a schematic diagram of the device; in fig. 2 - its constructive implementation.

Внутри корпуса - латунного цилиндра / с навинченной на него гайкой 2 установлен пружинный динамометр, состо щий из двух стальных скоб 5 и 4; над динамометром установлено кольцо 5, в котором при помощи скобок 6 и винтов закреплена тензометрическа  мембрана 7 (с четырьм  тензометрами ./,), жестко св занна  с винтом 8, ввинченным во втулку Я котора  припа на ко дну сильфонной мембраны 10. Таким образом, при деформации сильфонной мембраны W винт 8 своей головкой нажимает на скобы 3 и 4 прул инного динaмo eтpa, обусловлива  их деформацию. Так как тензомембрана 7 .св зана с винтом 8 Жестко, она также деформируетс ; кра  тензомембраны закреплены не жестко, а скольз т в пазах скобок 6.Inside the case of a brass cylinder / with nut 2 screwed on it, a spring dynamometer is installed, consisting of two steel brackets 5 and 4; A ring 5 is installed above the dynamometer, in which, using brackets 6 and screws, a strain gauge membrane 7 (with four strain gauges ./,) is fixed, rigidly connected with a screw 8 screwed into the sleeve I which is soldered to the bottom of the bellows membrane 10. Thus, during the deformation of the bellows membrane W, the screw 8 with its head presses on the brackets 3 and 4 of the screw of the other dinam, causing their deformation. Since the strainer membrane 7. Is screwed with screw 8 is rigid, it also deforms; The edges of the strain gauge are not rigidly fixed, but are slid in the slots of the brackets 6.

При такой конструкции соответствие между наружным давлением и разбалансировкой моста на тензометре полностью определ етс  упругими свойствами скоб 3 и 4. Таким образом, благодар  применению пружинного динамометра в сочетании с сильфонной мембраной обеспечиваетс  линейность показаний прибора.With this design, the correspondence between the external pressure and the unbalance of the bridge on the strain gauge is completely determined by the elastic properties of brackets 3 and 4. Thus, by using a spring dynamometer in combination with a bellows membrane, the instrument reads linearity.

Сильфонна  мембрана впа на в кольцо 5, которое вставлено в корпус /. Резиновое уплотнительное кольцо 11 при помощи болтов /2 сжимаетс  нажимным кольцом 13, чем создаетс  полна  герметизаци  внутреннего объема прибора.The bellows membrane is inserted into the ring 5, which is inserted into the housing /. The rubber sealing ring 11 is compressed with the aid of bolts / 2 by the pressure ring 13, which creates a complete sealing of the internal volume of the device.

Примен   скобы 3 v, 4 различной упругости, можно использовать прибор дл  различных диапазонов измерени , в силу чего прибор с той же тензомембраной и с той же сильфонной мембраной может работать в установках с разны.ми высотами уровн  жидкости: в балластных цистернах плавучих доков и судов, в топливных танках , дл  измерени  осадки судна и т. д. Точность измерений 1,0-1,2%.Using brackets 3 v, 4 of different elasticity, the device can be used for different measuring ranges, whereby the device with the same strain gauge and the same bellows membrane can work in installations with different heights of the liquid level: in ballast tanks of floating docks and ships , in fuel tanks, to measure ship draft, etc. Measurement accuracy 1.0-1.2%.
