Abstract
A ceramic pressure measuring cell with a basic body ( ), a diaphragm ( ) connected to the basic body ( ) to form a measuring chamber ( ), which during operation undergoes a deflection dependent on a pressure (p -p ) to be measured and the deflection of which is registered by means of an electromechanical transducer and is made accessible for further evaluation and/or processing, and a bore ( ) which penetrates the basic body ( ) and into which a small pressure tube ( ) is soldered in a pressure-resistant and gastight manner, and via which a pressure (p , p ) is introduced into the measuring chamber ( ), is provided, in which a volume inside the measuring cell and the small pressure tube is precisely known, since the mechanical stop ( ) fixes a depth of penetration of the small pressure tube ( ) into the basic body ( ).
