A burst disk assembly is configured for use in a pressurized gas system for venting pressurized gas from the system in the event that the gas exceeds a predetermined pressure. A plug has a tapered cylindrical shape with a minimum cross-section that is less than a body plug region open cross-section of the assembly, and a maximum cross-section that is greater than the body plug region open cross-section. The plug defines, at an end adjacent the minimum cross-section, a disk face. A frangible disk is positioned in the plug region and is sandwiched between the plug disk face and a body radial wall of the assembly.
A measurement pickup is provided offering a high measure of safety and having a measurement pickup housing, a sensor element arranged in the measurement pickup, at least one connection element closing the measurement pickup housing, and an excess-pressure protection device, especially a burst disk or a pressure relief valve, integrated in the connection element, which serves to effect a pressure equalization with an environment of the measurement pickup in the case of a pressure overload in the measurement pickup.
