摘要： In a measurement system for a pressure gage which has a bourdon tube spring as well as a spring support, the bourdon tube spring is made of a metallic material and the spring support is made of a polymer plastic. The connection between the bourdon tube spring and the spring support is made by means of a metallic transition element which has a recess into which the fixed end of the bourdon tube spring is glued or soldered, and which has engagement means formed on it which are in form-fitting engagement with the spring support. The compound assembly comprising the transition element and the spring support combines the cost advantage of the fabrication of the spring support from plastic with the mechanical advantages and antileak advantages of a metal-to-metal connection for the connection of the bourdon tube spring to the spring support. The fabrication of the measurement system is carried out such that the compound assembly of the spring support and the transition element is produced first, before the connection with the bourdon tube spring is made in conventional manner.
