補償毛細管設計
具有補償毛細管,幫助平衡高壓側毛細管和低壓側毛細管之間的填充流體的體積和溫度。 這種解決方案可以減少環境溫度漂移的影響,無論是日夜溫差,季節變化,還是陰天變冷。
該補償毛細管連接到傳送器的高壓側,並沿低壓毛細管運行。填充流體的體積在傳送器的兩側之間相同並平衡它們之間的環境溫度。
環境溫度漂移
環境溫度是製程周圍的溫度。 如果水箱位於室外,則傳送器和毛細管系統可以看到日夜,季節,甚至是陰天到晴天的溫度波動。 這種溫度變化會像任何液體一樣影響填充液。 隨著變化,流體在毛細管內收縮和膨脹。 這可能導致讀數不準確。 讀數反映了填充液的變化,而不是液位的實際變化。
比較數據
以下數據顯示了由於陽光引起的溫度漂移對補償型和標準型差壓傳送器的影響。 通過僅在距離毛細管末端延伸50cm的區域和低壓側的隔膜密封件內改變溫度來模擬太陽光的影響。
當低壓側的溫度上升50℃時,標準型的輸出在10kPa的測量範圍內增加了14.0%。 同時,補償型的輸出僅增加了0.8%,這是標準型變化的13.2%。

DP Level transmitter configuration can be very time consuming. Yokogawa DPharp EJA/EJX Pressure transmitters realize reduction in man hours by smart level setup feature.
Differential pressure level measurement has an enemy- temperature. Temperature can have a negative effect on the accuracy of level measurement. This article covers why temperature has this effect and how it can be reduced.
