Abstract
Изобретение относитс к автомобилестроению и может быть использовано в химической, пищевой и др. отрасл х промышленности. Целью изобретени вл етс повышение точности и быстродействи датчика уровн жидкости. Дл этого в датчике жидкости, имеющем измерительный 1 и компенсационный 2 резисторы, включенные в мостовую схему, эти резисторы выполнены линейно прот женными и из фольги. Измерительный резистор выполнен таким образом, что его проводимость измен етс в зависимости от длины так же, как объем бака в зависимости от его уровн , что позвол ет измер ть уровень жидкости в баках сложной формы. Оба резистора размещены в трубке 5, котора в свою очередь помещаетс в бак. На нижнем конце трубки имеетс жиклер 6, а верхний конец сообщаетс с полостью бака, что делает датчик нечувствительным к кренам, вибраци м, ускорени м и позвол ет использовать его дл измерени уровн топлива в баках наземных транспортных средств. 4 ил.The invention relates to the automotive industry and can be used in the chemical, food and other industries. The aim of the invention is to improve the accuracy and speed of the liquid level sensor. To do this, in a fluid sensor having a measuring 1 and a compensation 2 resistors included in the bridge circuit, these resistors are made linearly and foil. The measuring resistor is designed in such a way that its conductivity varies depending on the length in the same way as the volume of the tank depending on its level, which allows measuring the level of liquid in tanks of complex shape. Both resistors are placed in tube 5, which in turn is placed in a tank. At the lower end of the tube there is a jet 6, and the upper end communicates with the cavity of the tank, which makes the sensor insensitive to rolls, vibrations, accelerations and allows it to be used to measure the level of fuel in the tanks of land vehicles. 4 il.
