OHR-B400轉速表要顯示轉速“轉/min”，參數要怎么設置？OHR頻率/轉速表接收的脈沖范圍多大，電壓幅值多大？
答：轉速表測量到的信號是頻率，單位是HZ也就是“脈沖/S”，要轉換成“轉/min”的話首先要把S轉換為分鐘，就要把比例因子改為60，這樣顯示的數值對應的單位就是“脈沖/min”，然后再看每轉有幾個脈沖，就把比例因子除以幾。例如，現在有個設備每轉是30個脈沖，要儀表上顯示的是“轉/min”，則把比例因子設置成2就可以（比例因子=1*60/每轉的脈沖數）。頻率測量范圍是：1~34KHZ，電壓幅值：0.3~12V，最小分別率：0.01HZ.

其次，西門子PLC硬件高度集成，已集成到各種小型化模塊中。此外，這些模塊是匹配的，并已被序列化和標準化。西門子公司是世界上好大的機電公司之一。西門子siamtic模塊化控制器具有很大的優勢。它可以購買和使用，長期的兼容性和可用性，可以在惡劣的環境下工作，模塊可以擴展和升級。電壓電流檢測電路：將檢測電壓電流與主電路電位隔離。驅動電路：驅動主電路裝置的電路。它與控制電路隔離，使主電路器件通斷。

羅斯蒙特3051壓力變送器選型手冊
一、工作原理
工作時，高、低壓側的隔離膜片和灌充液將過程壓力傳遞給灌充液，接著灌充液將壓力傳遞到傳感器中心的傳感膜片上。傳感膜片是一個張緊的彈性元件，其位移隨所受壓而變化（對于ＧＰ表壓變送器，大氣壓如同施加在傳感膜片的低壓側一樣）。ＡＰ絕壓變送器，低壓側始終保持一個參考壓力。傳感膜片的ｚｕｉ大位移量為０．００４英寸（０．１毫米），且位移量與壓力成正比。兩側的電容極板檢測傳感膜片的位置。傳感膜片和電容極板之間電容的差值被轉換為相應的電流，電壓或數字ＨＡＲＴ（高速可尋址遠程發送器數據公路）輸出信號。

電磁流量計可用于測量漿狀流體的流速。差壓流量計:這是最普通的流量技巧，包孕孔板、文丘里管和音速噴嘴。DP流量計可用于測量大多數液體、氣體和蒸汽的流速。DP流量計沒有移動部分，利用廣泛，易于應用。但堵塞后，它會產生壓力丟失，影響準確度。流量測量的準確度取決于壓力表的準確度。
西門子產品具有很強的抗振性，采用集中和分布式IO控制，近年來，西門子能夠有效地進入中國市場，并牢牢扎根于中國市場。這與西門子產品的質量和性能密切相關，包括S7-200、S7-300和S7-400。S7-200適用于制造一系列機械設備或作為一個獨立的解決方案。對于這樣一個工業化系統，模仿者很難分析出來某個子系統的程序是什么。

?當在爆炸性氣體環境下連接HART手操器之前，應確保回路中儀表的安裝符合本質安全或非易燃現場接線的準則。
?通電時，不得在爆炸性/易燃性環境下拆卸變送器表蓋。
2、觸電會導致死亡或者重傷：
?應避免與引線或接線端子相接觸。引線上可能存在的高壓會引起觸電。本產品關鍵零部件是膜頭，請注意在安裝及使用過程中不要損傷。
步驟1：安裝羅斯蒙特3051壓力變送器
①不要直接在壓力變送器電子外殼上施加轉矩。為了避免外殼損壞，只可以在六角形的過程接頭上施加轉矩。
