在生产工艺流程中,压力参数的测量是发展最早,应用最广的。早在1849年,法国仪器制造机械师波登(E.Bourdon)就获得了制造弹簧管的专利权,并制出实用弹簧管压力表。一百二十多年未,弹簧管压力表始终是主要的测压仪表。至今,用作压力仪表敏感元件的仍不外乎是弹簧管、螺旋管、板簧、波纹管、膜片、膜盒等。这些弹性元件制成的仪表,统称为弹性式压力表。弹性式压力表在工业自动化仪表中之所以长期占有其稳固的地位,除了测量范
In the production process, the measurement of pressure parameters is the earliest development, the most widely used. As early as 1849, E. Bourdon, a French machinery maker, won the patent for the spring tube and made a practical spring tube pressure gauge. One hundred and twenty years have not, spring tube pressure gauge is always the main manometer. So far, the pressure sensor used for sensitive components is nothing more than a spring tube, spiral tube, leaf spring, bellows, diaphragm, diaphragm boxes. Instruments made of these flexible elements, collectively referred to as the elastic pressure gauge. Flexible pressure gauges in the industrial automation instruments in the reason why the long-term occupy its solid position, in addition to measuring range
