Датчик массового расхода и температуры воздуха

Номер: RU0000183325U1

Полезная модель относится к области измерительной техники, в частности к датчикам массового расхода воздуха, потребляемого двигателем внутреннего сгорания (ДВС) автомобиля. Датчик содержит корпус, внутри которого расположен чувствительный элемент в виде упругой лопасти, и блок обработки сигналов. Сущность полезной модели состоит в том, что расход определяется по величине упругой деформации лопасти в форме треугольника, находящейся в потоке воздуха, при этом интегральный изгиб пропорционален массе проходящего воздуха. Для измерения интегрального прогиба на лопасть нанесены тензорезисторы. Тензорезисторы включены по схеме моста Уинстона, что обеспечивает высокую чувствительность и температурную компенсацию параметров цепи. Сигналы от измерительного моста поступают в электронную схему измерения массового расхода и температуры воздуха. Массовый расход воздуха определяется по измеренному значению интегрального прогиба лопасти, а температура воздуха – по значению полного тока моста. Технический результат - расширение функциональных возможностей, диапазона условий эксплуатации, упрощение конструкции и повышение точности измерения датчика массового расхода и температуры воздуха. 3 ил.

A tunable tunnel junction thermometry circuit includes a variable width tunnel junction between a test object and a probe. The junction width is varied and a change in thermovoltage across the junction with respect to the change in distance across the junction is determined. Also, a change in biased current with respect to a change in distance across the junction is determined. A temperature gradient across the junction is determined based on a mathematical relationship between the temperature gradient, the change in thermovoltage with respect to distance and the change in biased current with respect to distance. Thermovoltage may be measured by nullifying a thermoelectric tunneling current with an applied voltage supply level. A piezoelectric actuator may modulate the probe, and thus the junction width, to vary thermovoltage and biased current across the junction. Lock-in amplifiers measure the derivatives of the thermovoltage and biased current modulated by varying junction width.
