日本NAGANO KEIKI長野計(jì)器成立于1896年，是一家專門做壓力測(cè)量技術(shù)行業(yè)的公司，崇尚“以科技為本”的理念 ，是壓力計(jì)和壓力傳感器的領(lǐng)導(dǎo)者之一。近年來公司產(chǎn)品陣容也從壓力測(cè)量發(fā)展為相對(duì)全面德測(cè)量控制技術(shù)。
NAGANO KEIKI長野計(jì)器主營產(chǎn)品有壓力變送器，壓力開關(guān)，壓力傳感器，數(shù)字壓力表等等。

NAGANO KEIKI壓力開關(guān)CQ21系列介紹及選型
這是一種結(jié)構(gòu)簡單的壓力開關(guān)，其中波登管應(yīng)用于壓力傳感元件，其移動(dòng)直接作用于微動(dòng)開關(guān)。這些壓力開關(guān)有很多是為過程工業(yè)的報(bào)警和控制而制造的，其中很多開關(guān)在發(fā)電廠和化工廠有應(yīng)用效果。
根據(jù)波登管移動(dòng)直接作用于微動(dòng)開關(guān)的結(jié)構(gòu)，構(gòu)成部件的數(shù)量少并且表現(xiàn)出優(yōu)異的耐用性。
壓力范圍從低壓擴(kuò)展到高壓：0.1 MPa 到 70 MPa，符合廣泛的范圍。
該壓力開關(guān)主要針對(duì)火力發(fā)電廠開發(fā)，接線空間大，維護(hù)方便。
This is a pressure switch with simple construction in which a Bourdon tube is applied to the pressure sensing element and its move directly functions the microswitch. A lot of these pressure switches have been manufactured for the warning and control of process industry, and a lot of these switches have application results in power and chemical plants.
According to the construction by which a Bourdon tube move directly functions the microswitch, the number of constituent parts is small and excellent durability is demonstrated.
The pressure range extends extensively from low pressure to high pressure:0.1 MPa to 70 MPa, complying with extensive ranges.
This pressure switch has been developed mainly for thermal power stations, equipped with a large wiring space, assuring easy maintenance work.
