精度提高。早期電磁流量計(jì)精度一般為±1.5%~±2.5%。現(xiàn)在電磁流量計(jì)精度提高到±.5%~.1%。有的廠商已做±.2%的電磁流量計(jì)。勵(lì)磁方式改變。由早使用的交流工頻(5Hz)正弦波勵(lì)磁,改變?yōu)榈皖l矩形波勵(lì)磁(6.25Hz)。近開發(fā)的產(chǎn)品則采用雙頻波勵(lì)磁(低頻矩形波6.25Hz+高頻矩形波75Hz)。交流工頻勵(lì)磁是利用市電作為勵(lì)磁電源,電源頻率不穩(wěn)定,在測(cè)量電極上會(huì)產(chǎn)生一種磁通微分噪聲,使儀表零點(diǎn)漂移。

運(yùn)轉(zhuǎn)環(huán)境的檢查。
⑴PLC運(yùn)轉(zhuǎn)環(huán)境溫度在0~60℃。溫度過(guò)高將使得PLC內(nèi)部元件功能惡化和毛病添加,尤其是CPU會(huì)因“電子搬遷”表象的加快而下降PLC的壽數(shù)。溫度偏低,模仿回路的安全系數(shù)也會(huì)變小,超低溫時(shí)能夠致使操控體系動(dòng)作不正常。處置的方法是在操控柜裝置適宜的軸流電扇或許加裝空調(diào),并留意常常檢查。
⑵環(huán)境相對(duì)濕度在5%~95%之間。在濕度較大的環(huán)境中,水分簡(jiǎn)單通過(guò)模塊上的IC的金屬表面的缺點(diǎn)侵入內(nèi)部,致使內(nèi)部元件功能的惡化,使內(nèi)部絕緣功能下降,會(huì)因高壓或浪涌電壓而致使短路;在極端枯燥的環(huán)境下,MOS集成電路會(huì)因靜電而致使擊穿。
⑶定時(shí)吹掃內(nèi)部塵埃,以確保風(fēng)道的疏通和元件的絕緣。
⑷檢查PLC的裝置狀態(tài)。各PLC單元固定是不是結(jié)實(shí),各種I/O模塊端子是不是松動(dòng),PLC通訊電纜的子母連接器是不是刺進(jìn)并旋緊,外部連接線有無(wú)損害。
⑸檢查PLC的程序存儲(chǔ)器的電池是不是需求替換。
