FIELD: physics. ^ SUBSTANCE: sensor for pulsed pressure of liquid, gaseous and mixed media with non-steady temperature has a housing with a nozzle for inlet of the measured medium. The detecting element is in form of a multilayer measuring diaphragm and a separating diaphragm, whose centres and peripheral parts are rigidly connected. A strain-sensitive circuit with static thermal compensation elements is deposited onto the measuring diaphragm from the outside. The housing is put into a cover. The channel of the inlet nozzle is fitted, without spacing, with a multiturn auger-type swirler, the length of curvilinear channels äôks of which satisfies a given mathematical inequality. ^ EFFECT: minimising additional temperature error of measurements in case of thermal shock due to non-steady temperature of the working medium. ^ 4 cl, 6 dwg |
