產(chǎn)品介紹

3151DP高精度進口膜片差壓變送器作為一種高精度智能型的現(xiàn)場差壓參數(shù)的檢測儀表,用來測量各種介質(zhì)在液體,氣體和蒸汽狀態(tài)下 的差壓、壓力,液位的參數(shù),并將被測的差壓參數(shù)轉(zhuǎn)換成4-20mA標準電信號輸出,同時采用HART協(xié)議,具有與手操器或上位機進行通訊的功能,變送器具 有輸出參數(shù)組態(tài)功能,能適應(yīng)不同用戶的需要。它可以精確地測量差壓、液位、真空度和比重。

3151DP具有防塵結(jié)構(gòu),安裝、使用和調(diào)校都方便簡單。接線端子和電子線路板放置在變送器上部的密封電氣腔室內(nèi),且彼此相互隔離開。所以現(xiàn)場接線 時,放大器仍在密封狀態(tài)下工作。變送器具有反極性保護措施,防止由于電源接反而損壞變送器。工作時的容積變化量小于0.16毫升,可防止被測介質(zhì)液柱過大 變化,因而可不需為補償容積變化量而增置冷凝器或液位筒。變送器與被測介質(zhì)接觸部分的零部件,選用316L不銹鋼材料。采用表面貼裝的電子元件和插拔式設(shè) 計制造的印制電路板,使故障少,維護方便,通用性強,減少了備品備件,降低了維修成本。

產(chǎn)品特點

1完整的測量范圍:0-0.15kPa~42MPa, 多種選擇、應(yīng)用靈活,可以滿足絕大部分用戶的需求。

2、結(jié)構(gòu)小巧、堅固、抗振。一體化接線盒和本機零點和量程調(diào)整和LCD顯示組態(tài)按鈕,使安裝、校驗和運行簡化。

3、在變送器殼體上設(shè)計了非接觸式就地零點、量程調(diào)整和LCD液晶顯示參數(shù)組態(tài)按鈕,便于現(xiàn)場調(diào)整零點和量程及設(shè)置所需的現(xiàn)場顯示參數(shù)。

4采用固體、插接式印制線路板、模塊化結(jié)構(gòu),有助于故障檢修及減少備件庫存示參數(shù)。

5、阻尼可調(diào),提高了用戶的可選擇性。

6、智能電路,方便用戶操作。

7、具有獨立抗電磁干擾電路和軟件抗干擾設(shè)計,提高了產(chǎn)品的可靠性。

8、內(nèi)部具有測量溫度參數(shù)傳感器,提高了變送器環(huán)境溫度影響補償性能,由于該傳感器與被測介質(zhì)直接接觸,所以同時可獲得與傳感器所接觸的介質(zhì)的溫度信息。

9、變送器配置的現(xiàn)場數(shù)字顯示表可以直接顯示測量壓力值、輸出模擬電流值、被測壓力對應(yīng)設(shè)定量程的百分比值、傳感器本體與其被接觸介質(zhì)的溫度值。本項技術(shù)己申請。

10變送器提高了故障恢復(fù)能力,大大減少了變送器維護工作量。

11LCD液晶顯示表采用多參數(shù)循環(huán)顯示方式工作。

12具有HART協(xié)議遠程通訊功能,在實現(xiàn)壓力測量的同時,增加了傳感器本體與被接觸介質(zhì)的溫度檢測功能,為用戶提供了更多的現(xiàn)場工況信息,有利于用戶提高過程控制的效果。

13、具有全金屬密封的差動電容壓力傳感器的δ室結(jié)構(gòu)創(chuàng)新設(shè)計,使差壓(壓力)和溫度測量實現(xiàn)了重大改進和良好的穩(wěn)定性。
