產(chǎn)品詳情
山東中發(fā)L+B編碼器讀數(shù)頭GEL2444KZRT3K030廠家報價
當(dāng)然也有選擇進(jìn)口真空儀表設(shè)備，但是真空測控儀表、真空計，進(jìn)口的產(chǎn)品非常昂貴，是不是一定要選擇進(jìn)口產(chǎn)品呢？我們應(yīng)該如何選擇性價比高的真空計呢？根據(jù)多年從事真空計、真空數(shù)字式儀器儀表研制和應(yīng)用工作經(jīng)驗體會，有以下的幾點供大家參考，希望對大家有用。[B]，從真空測量機理的先進(jìn)性來考慮[/B]，應(yīng)該選擇采用新型傳感元件的真空計，如硅集成真空傳感器、陶瓷基片厚膜電路真空度傳感器、陶瓷電容式薄膜真空規(guī)等等；而傳統(tǒng)老式的熱傳導(dǎo)類（熱偶計、電阻計、皮拉尼計等等）雖然價格稍低些，但其精度低、穩(wěn)定性差、壽命短，按照產(chǎn)品標(biāo)準(zhǔn)測量精度誤差5%就合格；雖然現(xiàn)在也有數(shù)字化、但是畢竟是先天不足。

EVH5沒有得電：EVH5是比例壓力閥，它是由壓力閥放大器和PLC的176號對應(yīng)的輸出口控制。通過測量175，176就能判斷是哪一部分的故障。EVH9沒有得電：首先測量A2，C2看數(shù)控系統(tǒng)是否有給定信號輸出，如沒有應(yīng)檢查數(shù)字I/O的狀態(tài)，即J24的1.8，2.1，J26的1.5，1.6應(yīng)該得電。如A2，C2有給定信號輸出，再測量伺服閥放大器的輸出C6，C8就能判斷伺服閥放大器的好壞。滑塊無快進(jìn)滑塊的快進(jìn)是由下腔回油，依靠滑塊的重量在上腔形成負(fù)壓吸油產(chǎn)生的。
當(dāng)然也有選擇進(jìn)口真空儀表設(shè)備，但是真空測控儀表、真空計，進(jìn)口的產(chǎn)品非常昂貴，是不是一定要選擇進(jìn)口產(chǎn)品呢？我們應(yīng)該如何選擇性價比高的真空計呢？根據(jù)多年從事真空計、真空數(shù)字式儀器儀表研制和應(yīng)用工作經(jīng)驗體會，有以下的幾點供大家參考，希望對大家有用。[B]，從真空測量機理的先進(jìn)性來考慮[/B]，應(yīng)該選擇采用新型傳感元件的真空計，如硅集成真空傳感器、陶瓷基片厚膜電路真空度傳感器、陶瓷電容式薄膜真空規(guī)等等；而傳統(tǒng)老式的熱傳導(dǎo)類（熱偶計、電阻計、皮拉尼計等等）雖然價格稍低些，但其精度低、穩(wěn)定性差、壽命短，按照產(chǎn)品標(biāo)準(zhǔn)測量精度誤差5%就合格；雖然現(xiàn)在也有數(shù)字化、但是畢竟是先天不足。

EVH5沒有得電：EVH5是比例壓力閥，它是由壓力閥放大器和PLC的176號對應(yīng)的輸出口控制。通過測量175，176就能判斷是哪一部分的故障。EVH9沒有得電：首先測量A2，C2看數(shù)控系統(tǒng)是否有給定信號輸出，如沒有應(yīng)檢查數(shù)字I/O的狀態(tài)，即J24的1.8，2.1，J26的1.5，1.6應(yīng)該得電。如A2，C2有給定信號輸出，再測量伺服閥放大器的輸出C6，C8就能判斷伺服閥放大器的好壞。滑塊無快進(jìn)滑塊的快進(jìn)是由下腔回油，依靠滑塊的重量在上腔形成負(fù)壓吸油產(chǎn)生的。
