Description
(54) ДАТЧИК ДАВЛЕНИЯ(54) PRESSURE SENSOR
рвзйстсф 4 нагреваетс одновременно с твнэорезистором 5 при прохождении через него нзмеритв ьного тока. Температуры рабочего и компенсапионкого тензорезиоторов равны, в результате достигаетс более высока точность компенсации вли ни температуры на тензочувствительчость полупроводниковых тензорезисторов.The horn 4 is heated simultaneously with the TV resistor 5 as the current flows through it. The temperatures of the working and compensating strain gages are equal; as a result, a higher accuracy is achieved in compensating for the effect of temperature on the strain gages of semiconductor strain gages.
Наличие дополнительного тензорезнстора установленного параллельно рабочему, позвол ет пошлсвть точность измерений датчика давлени за счет снижени тем пвратурных погрешностей.The presence of an additional strain gauge installed parallel to the worker, allows the accuracy of the pressure sensor to be measured by reducing the volume error.
Ф ормула изобретени Formula of invention
Датчик давлени по авт. св. 296006, отлнчаюшнйс тем, что, с целью повышени точности за счет сш жени температуршзтх погрешностей, он снабжен дополнительным полупроводниковым тензорезистором, установленным параллельно рабочему в закрепленным с ним в одной точке.Pressure sensor on bus. St. 296006, differing from the fact that, in order to increase the accuracy due to cross-cutting temperature errors, it is equipped with an additional semiconductor strain gauge installed parallel to the worker in fixed with it at one point.
