更改智能型壓力變送器的量程范圍是我們?cè)趯?shí)際應(yīng)用中經(jīng)常會(huì)用到的一種操作。首先也是在智能型壓力變送器正常顯示時(shí)，屏幕上依次出現(xiàn)5個(gè)“0”閃爍后，等到右位閃爍時(shí)松手，按下S鍵，將智能型壓力變送器的顯示數(shù)字改成“00003”，按M鍵一次，液晶左下角顯示數(shù)字“3”。我們就進(jìn)入了智能型壓力變送器量程范圍的調(diào)節(jié)界面。這時(shí)按下S鍵一次，左側(cè)的箭頭開始閃爍，Z鍵是位移，S鍵是更改數(shù)字。右位閃爍時(shí)，按Z鍵小數(shù)點(diǎn)全亮，按S鍵可進(jìn)行小數(shù)點(diǎn)位置的選擇。輸入完畢后按M鍵進(jìn)行數(shù)據(jù)的保存，并切換到量程上限界面。此時(shí)，智能型壓力變送器液晶顯示左下角顯示“4”，接下來就是重復(fù)以上操作，更改成想要的量程后，按M鍵進(jìn)行保存即可。需要注意的是，如果不需要調(diào)整智能型壓力變送器的量程下限，可在進(jìn)入“3”后直接按下M鍵保存并跳過，進(jìn)入“4”的界面進(jìn)行調(diào)整量程上限。吉林水暖管道壓力變送器哪里買能與各種型號(hào)的動(dòng)圈式指示儀、數(shù)字壓力表、電子電位差計(jì)配套使用，也能與智能調(diào)節(jié)儀或計(jì)算機(jī)系統(tǒng)配套使用。</p><div

壓力變送器的精度。在質(zhì)量上分析，壓力變送器的精度是zui重要的技術(shù)參數(shù)。壓力變送器精度關(guān)系到整個(gè)測量系統(tǒng)的zui終結(jié)果。儀表的精度簡言之就是儀表測量值接近真值的準(zhǔn)確程度，通常用相對(duì)百分誤差（也稱相對(duì)折合誤差）表示。按儀表工業(yè)規(guī)定，儀表的精確度劃分成若干等級(jí)，簡稱精度等級(jí)。精度等級(jí)的數(shù)字越小，精度越高。我們可以從三個(gè)方面理解壓力變送器精度的概念：1、精度表示測量結(jié)果與真值之間的一致程度，它反映測量結(jié)果中系統(tǒng)誤差與隨機(jī)誤差的綜合。其定量特征可用測量的不確定度(或極限誤差)來表示。2、精度表示在一定條件下進(jìn)行多次測量時(shí)，所得測量結(jié)果彼此之間符合的程度，它反映測量結(jié)果中隨機(jī)誤差的影響程度。3、精度表示測量結(jié)果中系統(tǒng)誤差大小的程度，反映了規(guī)定條件下，測量結(jié)果中所有系統(tǒng)誤差的綜合。在價(jià)格上，壓力變送器的精度越高，其價(jià)格也越昂貴。在實(shí)際使用過程中，如果測量目的是定性分析，不必要選用juedui量值精度高的壓力變送器；如果是為了定量分析，必須獲得精確的測量值，就需選用精度等級(jí)能滿足要求的壓力變送器。 </p><p> 壓力表與壓力變送器的區(qū)別?小編特將兩者的概念介紹如下： </p> <p> 一、什么是壓力表? </p> <p> 壓力表一般直接裝在管道中，利用內(nèi)部的膨脹管感應(yīng)壓力，同時(shí)驅(qū)動(dòng)齒輪機(jī)構(gòu)使指針轉(zhuǎn)動(dòng)達(dá)到顯示壓力數(shù)值的效果。 </p> <p> 二、什么是壓力變送器? </p> <p> 壓力變送器一般用于工控自動(dòng)化中。安裝在需要讀取壓力的地方，可能為管道或者某個(gè)存儲(chǔ)罐，將氣體、液體等壓力信號(hào)轉(zhuǎn)變?yōu)殡娏骰蛘唠妷盒盘?hào)，這些電流或者電壓信號(hào)將提供給記錄儀、調(diào)節(jié)器、報(bào)警器等儀表，從而達(dá)到測量、記錄和調(diào)節(jié)的作用。 </p> <p> 可見壓力表和壓力變送器并非一個(gè)概念，各有其應(yīng)用領(lǐng)域及測量范圍. 壓力變送器在管道上使用，管內(nèi)無介質(zhì)，壓力不為零。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

在工業(yè)自動(dòng)化來領(lǐng)域，壓力變送器與差壓變送器都是不可缺少的一種測量儀表。我們就來分析一下壓力變送器和差壓變送器相同與不同之處。 </p> <p> 壓力變送器與差壓變送器的相同點(diǎn)： </p> <p> 工作原理相同：壓力變送器與差壓變送器都是通過壓阻效應(yīng)產(chǎn)生的電壓信號(hào)，經(jīng)過放大、零點(diǎn)和靈敏度溫度補(bǔ)償來實(shí)現(xiàn)其終的測量。 </p> <p> 輸出信號(hào)相同：不管是壓力變送器還是差壓變送器，都能進(jìn)行4～20 mA 的電流輸出、RS485 數(shù)字信號(hào)輸出和0～10 VDC、0～5 VDC等電壓信號(hào)輸出。 </p> <p> 壓力變送器與差壓變送器的不同點(diǎn)： </p> <p> 壓力端的不同：壓力變送器只能測量一個(gè)壓力端的壓力，而差壓變送器可以測量兩個(gè)壓力點(diǎn)的壓力，兩者壓力相減，正壓端壓力減負(fù)壓端壓力得出壓力差值。 </p> <p> 連接方式的不同：壓力變送器一般采用的都是螺紋連接，差壓變送器除了可采用螺紋連接，更多的則選用寶塔嘴和快接口的連接方式，可直接接相應(yīng)直徑的軟管。安裝更加方便。變送器的輸出信號(hào)傳輸?shù)街锌厥疫M(jìn)行壓力指示、記錄或控制。吉林水暖管道壓力變送器哪里買</p><p style="text-indent:25px">安裝時(shí)應(yīng)使變送器的壓力敏感件軸向垂直于重力方向，若安裝條件限制，應(yīng)安裝固定后調(diào)整變送器零位到標(biāo)準(zhǔn)值。陜西煙塵治理壓力變送器推薦廠家</p><p> 壓力變送器采用電流輸出的方式有很多優(yōu)勢：diyi、壓力變送器不易受寄生熱電偶和沿電線電阻壓降和溫漂的影響，常規(guī)導(dǎo)線就能滿足工況需求；可節(jié)省大量電纜線和安裝費(fèi)用。第二、當(dāng)壓力變送器電流源輸出電阻足夠大時(shí)，經(jīng)磁場耦合感應(yīng)到導(dǎo)線環(huán)路內(nèi)的電壓，不會(huì)產(chǎn)生明顯影響，因?yàn)楦蓴_源引起的電流極小，一般利用雙絞線就能降低干擾；三線制與四線制必須用屏蔽線，屏蔽線的屏蔽層要妥善接地。第三、電容性干擾會(huì)導(dǎo)致jieshouqi電阻產(chǎn)生有關(guān)誤差，對(duì)于4~ 20mA 兩線制環(huán)路， jieshouqi電阻通常為2508 （取樣Uou t=1~ 5V ）這個(gè)電阻小到不足以產(chǎn)生明顯誤差，因此，可以允許的電線長度比電壓遙測系統(tǒng)更長更遠(yuǎn)。第四、壓力變送器各個(gè)單臺(tái)示讀裝置或記錄裝置可以在電線長度不等的不同通道間進(jìn)行換接，不因電線長度的不等而造成精度的差異，從而實(shí)現(xiàn)分散采集、集中控制。第五、將4mA 用于零電平，使判斷開路與短路或壓力變送器損壞（ 0mA 狀態(tài)）十分方便。第六、壓力變送器的兩線輸出口非常容易增設(shè)一兩只防雷防浪涌器件，有利于安全防雷防爆。 </p> <p> <br /> 陜西煙塵治理壓力變送器推薦廠家</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2916135.html</p></div></div></div></div></div><div
