它的工作原理是利用旋轉(zhuǎn)質(zhì)量的離心力與轉(zhuǎn)角度或比例的原理而形成的轉(zhuǎn)速表。當(dāng)轉(zhuǎn)速表的軸轉(zhuǎn)動(dòng)時(shí)，離心器上重錘在慣性離心力的作用下離開(kāi)軸心，并通過(guò)傳動(dòng)裝置帶動(dòng)表針轉(zhuǎn)動(dòng)。軸的轉(zhuǎn)速根據(jù)指針在慣性離心力和彈簧彈力平衡是的位置來(lái)確定[1]。磁性轉(zhuǎn)速儀磁性轉(zhuǎn)速儀[2]利用旋轉(zhuǎn)磁場(chǎng)，在金屬罩帽上產(chǎn)生旋轉(zhuǎn)力，利用旋轉(zhuǎn)力與游絲力的平衡來(lái)指示轉(zhuǎn)速。磁性轉(zhuǎn)速表，是成功利用磁力的一個(gè)典范，是利用磁力原理的機(jī)械式轉(zhuǎn)速儀；一般就地安裝，用軟軸可以短距離異地安裝。磁性轉(zhuǎn)速儀，因結(jié)構(gòu)較簡(jiǎn)單。異地安裝時(shí)軟軸易損壞。用途編輯轉(zhuǎn)速表一般設(shè)置在儀表板內(nèi)，與車(chē)速里程表對(duì)轉(zhuǎn)速表轉(zhuǎn)速表(4張)稱地放置在一起。轉(zhuǎn)速表是按照磁性原理工作的，它接收點(diǎn)火線圈中初級(jí)電流中斷時(shí)產(chǎn)生的脈沖信號(hào)。
