加(jia)壓(ya)(ya)變(bian)送(song)(song)器輸出不變(bian)化，再加(jia)壓(ya)(ya)變(bian)送(song)(song)器輸出突(tu)然變(bian)化，泄壓(ya)(ya)變(bian)送(song)(song)器零位回不去。 產生此現(xian)象的原因極有可能是壓(ya)(ya)力(li)傳感器密(mi)封圈(quan)引起的。

是否符(fu)合(he)供電(dian)要(yao)求；電(dian)源與變(bian)送器及負載設備之間有無(wu)接線(xian)錯誤。如果變(bian)送器接線(xian)端子(zi)上無(wu)電(dian)壓(ya)或極性接反均可造成變(bian)送器無(wu)電(dian)壓(ya)信號(hao)輸出。

壓力傳感(gan)(gan)器(qi)(qi)及(ji)(ji)變(bian)(bian)送(song)器(qi)(qi)的外殼一般需接地，信號電(dian)纜線不得(de)與動(dong)力電(dian)纜混(hun)合鋪設，傳感(gan)(gan)器(qi)(qi)及(ji)(ji)變(bian)(bian)送(song)器(qi)(qi)周圍應(ying)避免有強電(dian)磁干擾。傳感(gan)(gan)器(qi)(qi)及(ji)(ji)變(bian)(bian)送(song)器(qi)(qi)在使用 變(bian)(bian)送(song)器(qi)(qi)（圖8）中應(ying)按行業規定(ding)進行周期檢定(ding)。
