Abstract: A method of assembling a pressure sensor is disclosed. The sensor includes an aneroid capsule and an electrical circuit secured to opposite sides of a first insulator. The capsule and circuit are electrically interconnected. Second and third insulators are assembled on opposite sides of the first insulator bearing against respective ones of the aneroid capsule and the electronic sensing circuit. The subassembly so formed then is partially inserted into the open end of a hollow can having a closed opposite end with a port therein. A vacuum is applied to the port to suck the subassembly into the hollow can.
