Abstract

1. Датчик давления с частотным выходным сигналом по а.с. №427256, отличающийся тем, что, с целью повышения точности и стабильности выходной характеристики датчика при измерении абсолютных давлений, в нем цилиндрический резонатор заключен в трубку круглого сечения из вакуумплотного диэлектрика, концы которой через переходные втулки из металла, образующего согласованный спай с материалом диэлектрика, соединены с концами резонатора и образуют с ним и с трубкой из диэлектрика герметичную кольцевую камеру.2. Датчик по п.1, отличающийся тем, что трубка из диэлектрика соединена с концами резонатора фланцевым соединением, плоские участки которого образованы с одной стороны переходными втулками, соединенными с резонатором, а с другой - развитыми торцовыми поверхностями трубки из диэлектрика, либо промежуточными втулками из металла, соединенными с трубкой из диэлектрика.3. Датчик по пп.1 и 2, отличающийся тем, что диэлектрическая трубка выполнена из конденсаторной керамики на основе титаната бария или цирконато-титаната свинца.1. Pressure sensor with a frequency output signal according to a.s. No. 427256, characterized in that, in order to improve the accuracy and stability of the output characteristic of the sensor when measuring absolute pressures, a cylindrical resonator is enclosed in a circular section tube of a vacuum-tight dielectric, the ends of which through transitional sleeves of metal forming a consistent junction with the material of the dielectric, connected to the ends of the resonator and form with it and with the dielectric tube a sealed annular chamber. A sensor according to claim 1, characterized in that the dielectric tube is connected to the ends of the resonator by a flange joint, the flat portions of which are formed on one side by transition sleeves connected to the resonator, and on the other by the developed end surfaces of the dielectric tube or intermediate sleeves of metal connected to a dielectric tube. Sensor according to claims 1 and 2, characterized in that the dielectric tube is made of capacitor ceramics based on barium titanate or lead zirconato-titanate.
