Abstract
A component for a gauge comprising a bourdon tube having a first end and a second end. A socket is joined to the first end of the bourdon tube and a closure member is joined to the second end of the bourdon tube. At least one of the bourdon tube and the closure member comprises a copper nickel alloy and/or the socket comprises a nickel silver alloy. In addition, a low temperature soldering material, such as a tin-bismuth soldering material, was used to affix the socket to the bourdon tube and the closure member to the bourdon tube. Preferably, the components contain substantially no free copper. Such a component resists corrosion, especially corrosion formed when certain fluids are used with such components.
Claims25
A component for a gauge comprising:
- a bourdon tube having a first end and a second end;
- a socket joined to the first end of said bourdon tube;
- and
- a closure member joined to the second end of said bourdon tube,
