解析壓力開關(guān)的遲滯性
壓力開關(guān)在設(shè)置時，要考慮到工藝要求的壓力范圍和現(xiàn)場被測壓力的脈動情況，否則如果沒有考慮到這兩點，很容易造成遲滯數(shù)值的偏大。
由于壓力開關(guān)本身的滯后性，壓力開關(guān)使用時多多少少都會帶回差，即壓力遲滯：當(dāng)被校準(zhǔn)壓力達(dá)到設(shè)定值時，壓力開關(guān)不動作，只有當(dāng)壓力變化了一部分之后，壓力開關(guān)才開始動作，壓力的從低到高，再由高到低這兩個動作點之間的壓力差便稱為遲滯。因此，壓力開關(guān)在出廠之前，都要經(jīng)過嚴(yán)格校準(zhǔn)，如果內(nèi)部有修復(fù)機構(gòu)可以進(jìn)行適當(dāng)修復(fù)，則為合格的，否則生產(chǎn)的壓力開關(guān)都為不合格。
壓力開關(guān)本身的遲滯性與它所具有的遲滯性設(shè)置范圍是有所區(qū)別的，本身帶的遲滯性不能設(shè)定，且回差數(shù)值較小，而壓力開關(guān)具有的遲滯性設(shè)置范圍則是為了滿足工藝要求而設(shè)定的數(shù)值。
