…Elastic materials include brass, phosphor bronze, beryllium copper, stainless steel, and nickel spun C, while for high pressures, special steels such as chrome steel, Monel, and chrome molybdenum steel are used. Bourdon tube and diaphragm pressure gauges are available for low to high pressures, while bellows and hollow aerial pressure gauges have high pressure sensitivity and are primarily used to measure atmospheric pressure and low pressures. The deformation of the elastic element is magnified and indicated by a mechanical magnifying and indicating mechanism or an electrical transducer (displacement or strain transducer), and the pressure is measured. … *Some of the terminology used to refer to "air-filled pressure gauges" is listed below.

…弾性材料には,黄銅,リン青銅,ベリリウム銅,ステンレス鋼,ニッケルスパンCなどが用いられ,高圧用には,クロム鋼,モネル,クロムモリブデン鋼などの特殊鋼を使用する。ブルドン管形圧力計とダイヤフラム形圧力計は低圧用から高圧用まであり,ベローズ形圧力計と空ごう形圧力計は圧力感度が大きいため,主として気圧や低圧力の測定用である。弾性素子の変形量は機械式拡大指示機構,あるいは電気式変換器(変位またはひずみ変換器)により拡大,指示され,圧力が測られる。… ※「空ごう形圧力計」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
