Abstract
Изобретение относитс к измеритель- л ной технике и может быть использовано дл измерени давлени жидкостей и газов. Целью изобретени вл етс повышение чувствительности и точности измерени , это достигаетс введением селективной обратной св зи в автогенератор 13 при помощи цепи обратной акустической св зи, включающей пьезопреобразователи 7 и 8, жидкость 5, уголковый отражатель 6, размещенный на упругом чувствительном элементе 4. Отражающие , плоскости отражател расположены под пр мым углом друг к другу и обращены к пьезопреобразователю, установленному на корпусе. 2 ил.The invention relates to a measuring technique and can be used to measure the pressure of liquids and gases. The aim of the invention is to increase the sensitivity and accuracy of measurement, this is achieved by introducing selective feedback into the self-oscillator 13 using a feedback acoustic circuit including piezoelectric transducers 7 and 8, liquid 5, corner reflector 6 placed on the elastic sensitive element 4. Reflecting, the reflector planes are located at a right angle to each other and face the piezoelectric transducer mounted on the housing. 2 Il.
