壓力表pressuregauge壓力表(英文名稱:pressuregauge)是指以彈性元件為敏感元件，測量并指示高于環(huán)境壓力的儀表，應(yīng)用極為普遍，它幾乎遍及所有的工業(yè)流程和科研領(lǐng)域。在熱力管網(wǎng)、油氣傳輸、供水供氣系統(tǒng)、車輛維修保養(yǎng)廠店等領(lǐng)域隨處可見。尤其在工業(yè)過程控制與技術(shù)測量過程中，由于機(jī)械式壓力表的彈性敏感元件具有很高的機(jī)械強(qiáng)度以及生產(chǎn)方便等特性，使得機(jī)械式壓力表得到越來越***的應(yīng)用。壓力表工作原理是通過表內(nèi)的敏感元件(波登管、膜盒、波紋管)的彈性形變，再由表內(nèi)機(jī)芯的轉(zhuǎn)換機(jī)構(gòu)將壓力形變傳導(dǎo)至指針，引起指針轉(zhuǎn)動來顯示壓力。壓力表上mpa是什么意思？森垚儀表回答：壓力表上的Mpa是壓強(qiáng)單位，Mpa（兆帕）。。在國際單位制中，壓強(qiáng)的單位是帕斯卡，簡稱帕（Pa），即牛頓/平方米（N/m2）。壓強(qiáng)的常用單位還有巴（bar）、千帕（kpa）、兆帕（Mpa）、pSI等。衛(wèi)生型隔膜表一般用哪種材質(zhì)。浙江數(shù)字壓力表讀數(shù)</p><p
