要考慮系統(tǒng)的比較大壓力。一般來說，壓力變送器器壓力范圍比較大值應該達到系統(tǒng)比較大壓力值的1．5倍，眉山壓力變送器銷售。一些水壓和過程控制，有壓力尖峰或者連續(xù)的脈沖。這些尖峰可能會達到“比較大”壓力的5倍甚至10倍，眉山壓力變送器銷售，眉山壓力變送器銷售，可能造成變送器的損壞。連續(xù)的高壓脈沖，接近或者超過變送器的比較大額定壓力，會縮短變送器的實用壽命。但提高變送器額定壓力會**變送器的分辨率?？梢栽谙到y(tǒng)中使用緩沖器來減弱尖峰，這會降低傳感器的響應速度。

2、防止渣滓在導管內(nèi)沉積； </p> <p> 3、測量液體壓力時，取壓口應開在流程管道側面，以避免沉淀積渣； </p> <p> 4、測量氣體壓力時，取壓口應開在流程管道頂端，并且變送器也應安裝在流程管道上部，以便積累的液體容易注入流程管道中； </p> <p> 5、導壓管應安裝在溫度波動小的地方； </p> <p> 6、測量蒸汽或其它高溫介質時，需接加緩沖管（盤管）等冷凝器，不應使變送器的工作溫度超過極限； </p> <p> 7、冬季發(fā)生冰凍時，安裝在室外的變送器必需采取防凍措施，避免引壓口內(nèi)的液體因結冰體積膨脹，導至傳感器損壞； </p> <p> 8、測量液體壓力時，變送器的安裝位置應避免液體的沖擊（水錘現(xiàn)象），以免傳感器過壓損壞； </p> <p> 9、接線時，將電纜穿過防水接頭（附件）或繞性管并擰緊密封螺帽，以防雨水等通過電纜滲漏進變送器殼體內(nèi)。眉山壓力變送器銷售</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="眉山壓力變送器銷售,壓力變送器"

檢查安裝孔的尺寸：如果安裝孔的尺寸不合適，傳感器在安裝過程中，其螺紋部分就很容易受到磨損。這不僅會影響設備的密封性能，而且使壓力傳感器不能充分發(fā)揮作用，甚至還可能產(chǎn)生安全***。只有合適的安裝孔才能夠避免螺紋的磨損（螺紋工業(yè)標準1/2-20 </p> <p> UNF 2B），通?？梢圆捎冒惭b孔測量儀對安裝孔進行檢測，以做出適當?shù)恼{(diào)整。 </p> <p> 保持安裝孔的清潔：保持安裝孔的清潔并防止熔料堵塞對保證設備的正常運行來說十分重要。在擠出機被清潔之前，所有的壓力傳感器都應該從機筒上拆除以避免損壞。在拆除傳感器時，熔料有可能流入到安裝孔中并硬化，如果這些殘余的熔料沒有被去除，當再次安裝傳感器時就可能造成其頂部受損。清潔工具包能夠將這些熔料殘余物去除。然而，重復的清潔過程有可能加深安裝孔對傳感器造成的損壞。如果這種情況發(fā)生，就應當采取措施來升高傳感器在安裝孔中的位置。
