壓力開關使用在管道中的注意事項
目前工業上的壓力開關大多數都是使用在管道中，測量管道壓力的，為了獲得最佳測量效果，今天由小編為您詳細介紹在管道中使用壓力開關時的注意事項。
1.安裝時，應避免壓力開關與腐蝕性介質或者高溫介質的直接接觸，并安裝在溫度和壓力都波動較小的位置，同時還要防止沉積物聚積在管道之內。
2.接線時，為了防止雨水侵入電纜，影響壓力開關的殼體，需將電纜穿過防水接頭并擰緊螺釘。
3.在測量氣體壓力時，取壓口應設在管道頂端，而壓力開關則應安裝在管道上方，防止液體流入管道中；測量液體壓力時，為了防止積渣，取壓口應設在管道側面。
4.為了防止冬季因溫度過低導致的壓力開關結冰，因適當采取防凍措施。
