Gasgefüllte thermo-elastische Vorrichtung zur Druck- oder Temperaturmessung

摘要

A bourdon tube for gas and liquid-filled thermometers and pressure gauges constructed by edge welding two strips of isoelastic nickel alloy to form a wall to wall low volume bourdon tube that exhibits a low ambient temperature effect and improved rangeability over all existing bourdon tubes used for temperature and pressure measurement and control.
