儀表能適應(yīng)特殊場(chǎng)合,各種工作條件,廣泛應(yīng)用于石油、化工、機(jī)械、冶金、核能技術(shù)及開(kāi)關(guān)頻繁的工藝流程。


技術(shù)參數(shù):











測(cè)量范圍


0~0.16;0~0.25;0~0.4;0~0.6;0~2.5;0~4;0~6;0~10;0~16;0~25;0~40;0~60

3、儀表為垂直向下直接安裝式,可直接安裝在被測(cè)管道壓力接口上,安裝時(shí)避免儀表連接螺紋與表前閥之間形成“封閉壓力”(觀察示值,注意有壓力響應(yīng)時(shí)間),如果形成該壓力,應(yīng)及時(shí)消除,否則會(huì)造成測(cè)量元件損壞、介質(zhì)泄漏。

大三位半液晶顯示,直觀、清晰;不銹鋼接口與多種介質(zhì)兼容。主要應(yīng)用于石油化工、煤礦液壓、電站、汽車電子、液位測(cè)量等。它具有防水、防震結(jié)構(gòu),特別適于野外無(wú)電源情況下的壓力測(cè)量,帶調(diào)零裝置,方便現(xiàn)場(chǎng)使用。數(shù)顯壓力表采用大容量鋰離子電池供電,功耗低,可長(zhǎng)期連續(xù)工作,自動(dòng)光控或磁控開(kāi)關(guān)能延長(zhǎng)電池工作時(shí)間,當(dāng)顯示LOBAT時(shí)提示電池電量不足,應(yīng)使用專用充電器及時(shí)充電(充電器另配)。
主要技術(shù)指標(biāo):
1.顯示:3位或4位LED、LCD2.

測(cè)量范圍一般與在0.1Pa至1000Pa。
與皮拉尼電阻規(guī)一樣,這種規(guī)也需要在不同的使用氣體下標(biāo)定。
熱陰極電離規(guī)
如右圖所示,熱陰極電離規(guī)中,由熱陰極即燈絲發(fā)射電子,電離真空中的氣體分子,產(chǎn)生離子,由收集極收集產(chǎn)生的離子,形成離子電流,通過(guò)測(cè)量離子電流的大小即可推算出真空中氣體分子的密度,進(jìn)而得到氣壓大小。
這種規(guī)的測(cè)量范圍一般為1.0E-05Pa至0.1Pa。
經(jīng)改進(jìn)后的熱陰極電離規(guī),Bayard-Alpert規(guī),可以將測(cè)量下限降低至1.0E-09Pa。
由于不同氣體在相同氣壓下的電離率不同,這種規(guī)在使用時(shí)也需要在不同氣體下進(jìn)行標(biāo)定。
冷陰極電離規(guī)
