Description

Известны датчики дл  измерени  быстроиеременных давлении с тензометрическим преобразователем, содержащие чувствительный элемент, выполненный в виде тонкостенного цилиндра, одно основание которого укреплено в корпусе с проволочными тензометрами, наклеенными по образующей , а другое упираетс  в мембрану. Однако такие датчики имеют большую температурную погрешность.Sensors are known for measuring fast and variable pressure with a strain gauge transducer, containing a sensitive element made in the form of a thin-walled cylinder, one base of which is fixed in a housing with wire strain gauges glued along the generatrix and the other abutting the membrane. However, such sensors have a large temperature error.

В описываемом датчике указанный недостаток устранен тем, что дл  уменьшени  температурной погрешности датчика оба основани  цилиндра закреплены в корпусе, а внутренн   поверхность цилиндра снабжена по ском, в который упираетс  шток, прилегающий к мембране.In the sensor described, this drawback is eliminated by the fact that, in order to reduce the temperature error of the sensor, both bases of the cylinder are fixed in the housing, and the inner surface of the cylinder is provided with a junction that abuts the stem adjacent to the membrane.

На чертеже изображен датчик.The drawing shows the sensor.

Датчик дл  измерени  быстропеременных давлений с текзометрическим преобразователем состоит из корпуса /, чувствительного элемента, выполненного в виде цилиндра 2, верхнее 3 и нижнее 4 основани  которого закреплены в корпусе /, мембраны 5 и штока 6Мембрана 5, воспринимающа  давление, передает его чувствительному элементу посредством штока 6, прилегающего нижним концом к мембране 5, а верхним концом упирающегос  в по сок 7 на внутренней поверхности цилиндра 2, расположенный симметрично относительно оснований 5 и 4 цилиндра 2. При этом верхн   половина цилиндра 2 сжимаетс , а нижн   половина-раст гиваетс .A sensor for measuring rapidly variable pressures with a textometric transducer consists of a housing /, a sensing element made in the form of a cylinder 2, the upper 3 and lower 4 bases of which are fixed in the housing /, the membrane 5 and the rod 6Membrane 5, which receives pressure, transmits it to the sensitive element by means of a rod 6, adjacent the lower end to the membrane 5, and the upper end abutting on juice 7 on the inner surface of the cylinder 2, located symmetrically relative to the bases 5 and 4 of the cylinder 2. In this case, the upper olovina cylinder 2 is compressed, and the lower half-stretched.

Тензометры 5 и 9, составл ющие полумост сопротивлений и наклеенные по образующей цилиндра (в верхней и нижней его части), преобразуют деформацию цилиндра в электрический сигнал.Strain gauges 5 and 9, constituting a half-bridge of resistances and glued along the generator of the cylinder (in its upper and lower parts), convert the deformation of the cylinder into an electrical signal.
