差動電容式壓力傳感器的受壓膜片電極位于兩個固定電極之間,構成兩個電容器。在壓力的作用下一個電容器的容量增大而另一個則相應減小,測量結果由差動式電路輸出。它的固定電極是在凹曲的玻璃表面上鍍金屬層而制成。過載時膜片受到凹面的保護而不致破裂。差動電容式壓力傳感器比單電容式的靈敏度高、線性度好,但加工較困難(特別是難以保證對稱性),而且不能實現對被測氣體或液體的隔離,因此不宜于工作在有腐蝕性或雜質的流體中。
四、電磁壓力傳感器
多種利用電磁原理的傳感器統稱,主要包括電感壓力傳感器、霍爾壓力傳感器、電渦流壓力傳感器等。

EJA壓力變送器原理工作
在工作時由單晶硅諧振式傳感器上的兩上H形的振動梁分別將差壓和壓力信號轉換成電流頻率信號,再將其傳達到脈沖計數器上,然后將兩頻率之差直接傳遞到CPU上進行數據處理,經D/A轉換器轉換成與之相對應的輸入信號4-20mADC的輸出信號,并在模擬信號上疊加一個BRAIN或者HART數字信號進行通信。
EJA壓力變送器的工作原理:當被測介質的壓力值直接作用在傳感器的膜片上時,此時膜片就會產生與介質壓力成正比的微位移,使傳感器的電阻值發生變化,并用電子線路檢查發生的變化,然后轉化成為一個與壓力值對應的標準測量信號。

壓力變送器主要性能
1、使用被測介質廣泛,可測油、水及與316不銹鋼和304不銹鋼兼容的糊狀物,具有一定的防腐能力;
2、高準確度、高穩定性、選用進口原裝傳感器,線性好,溫度穩定性高;
3、體積小、重量輕、安裝、調試、使用方便;
4、不銹鋼全封閉外殼,防水好;
5、壓力傳感器直接感測被測液位壓力,不受介質起泡、沉積的影響。
根據系統的大過載
系統的大過載應小于變送器的過載保護極限,否則會影響變送器的使用壽命甚至損壞變送器。通常壓力變送器的安全過載壓力為滿量程的2倍。

2、具體調校:A對變送器進行零點修正
B加壓標定,實際標定砝碼值/顯示值=FC滿量程修正(0-1.5)
3、有規律加壓并回零檢查傳感器線性和重復性來判斷傳感器穩定性

3.3防止振蕩發生
差壓變送器會在阻力不相等時會突出微分器的特性。一般流量輸送管道的主要傳輸方式為泵或壓氣機,上述兩種自身就有規則的脈動現象和管道中流體的擴張、收縮問題,從而使傳輸過程中出現振蕩。對此,管道流量測量的取樣點位置有嚴格要求,必須在有足夠長度的直管段上,以求取得流體介質的平穩流速,取樣點的上游直管段要大于下游直管段,具體要求數值由設計標定;另外,可在測量管線上放置0.5~1.5孔徑的墊子來增加阻力,起到減少流量管線脈動影響。
綜上所述,近年來,隨著壓力測量和控制在工業生產中的普遍應用,相應的帶動了部分自動化技術。尤其壓力變送器為適應工業控制、醫學測試及航空工業等方面的要求,逐漸往高精度化、智能化、集成化的方向發展。自動化儀表作為電氣工程自動化控制下的特殊及重要門類,是采集信息的關鍵部分,可將氣體、液體或蒸汽壓力、液位及流量等工藝參數轉化統一的標準信號,實現各設備間的信息交換及共享,從而高效完成電氣工程監控和協調任務,確保其安全運行。
