style="text-indent:25px">變送器的種類很多，按工作能源分，有氣動(dòng)變送器、電動(dòng)變送器；按被測(cè)參數(shù)分，有差壓、壓力、流量、溫度、液位等變送器。變送器在儀器、儀表和工業(yè)自動(dòng)化領(lǐng)域中起著舉足輕重的作用。與傳感器不同，變送器除了能將非電量轉(zhuǎn)換成可測(cè)量的電量外，一般還具有一定的放大作用。壓力變送器也稱差變送器，主要由測(cè)壓元件傳感器、模塊電路、顯示表頭、表殼和過程連接件等組成。它能將接收的氣體、液體等壓力信號(hào)轉(zhuǎn)變成標(biāo)準(zhǔn)的電流電壓信號(hào)，以供給指示報(bào)警儀、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測(cè)量、指示和過程調(diào)節(jié)。</p><p style="text-indent:25px">儀器儀表檢修方法：電容旁路法：當(dāng)某一電路產(chǎn)生比較奇怪的現(xiàn)象，例如顯示器混亂時(shí)，可以用電容旁路法確定大概出故障的電路部分。隔離法：故障隔離法不需要相同型號(hào)的設(shè)備或備件作比較，而且安全可靠。根據(jù)故障檢測(cè)流程圖，分割包圍逐步縮小故障搜索范圍，再配合信號(hào)對(duì)比、部件交換等方法，一般會(huì)很快查到故障之所在。敲擊法：經(jīng)常會(huì)遇到儀器運(yùn)行時(shí)好時(shí)壞的現(xiàn)象，這種現(xiàn)象絕大多數(shù)是由于接觸不良或虛焊造成的。對(duì)于這種情況可以采用敲擊與手壓法。儀器是工業(yè)生產(chǎn)的“倍增器”，是科學(xué)研究的“先行官”。</p><div
