智能型在線式側(cè)裝密度計(jì)的溫度補(bǔ)償該怎么算
密度計(jì)的溫度補(bǔ)償并不是說補(bǔ)償?shù)蕉嗌龠m合,而是要按照測(cè)量時(shí)實(shí)際的情況來補(bǔ)償?shù)模⒉皇钦f想補(bǔ)多少就補(bǔ)多少。
密度計(jì)的溫度補(bǔ)償原理是:使用水當(dāng)測(cè)量溶液時(shí),密度計(jì)能測(cè)得樣品對(duì)水之比重值,而水的比重會(huì)隨著水的溫度變化而變化,所以需要以水4℃比重1.0000為基礎(chǔ)加以溫度補(bǔ)償。
對(duì)于水的溫度補(bǔ)償系數(shù),儀特諾固體密度計(jì)系列產(chǎn)品型號(hào),都已存入攝氏0~49℃的記憶值。

/主要特點(diǎn)
1、采用一體化結(jié)構(gòu)的兩線制變送器,無活動(dòng)部件維護(hù)簡(jiǎn)單。
1. Two wire transmitter with integrated structure, no moving parts and easy maintenance.
2、四位半數(shù)字液晶顯示。
2. Four and a half digit LCD.
3、安裝使用方便,插入液體即可顯示讀數(shù)。
3. It is easy to install and use, and the reading can be displayed by inserting liquid.
4、使用于流體或靜止液體,適合于管道和罐體安裝。
4. Used for fluid or static liquid, suitable for pipeline and tank installation.
5、溫度和密度兩個(gè)參數(shù)可交替顯示,便于進(jìn)行行業(yè)標(biāo)密換算。
5. Temperature and density can be displayed alternately, which is convenient for industry standard density conversion.
6、連續(xù)在線測(cè)量液體密度無過程中斷,可直接用于生產(chǎn)過程控制。
6. Continuous on-line measurement of liquid density without process interruption can be directly used for production process control.
7、接觸液體部件全部為幾種介質(zhì)不銹鋼材料制造,安全;衛(wèi)生。
7. All parts contacting liquid are made of stainless steel with several mediums, safe and sanitary.
測(cè)試前用溫度計(jì)量出水的實(shí)際溫度之后,將相應(yīng)溫度修改成溫度計(jì)所顯示之溫度即可。(水溫相差6℃則比重將相差0.001)。儀特諾密度計(jì)儀器出廠時(shí)機(jī)器默認(rèn)溫度為25℃。
運(yùn)用阿基米德原理浮力法測(cè)固體密度,用純水作為測(cè)量介質(zhì),既經(jīng)濟(jì)實(shí)惠,又方便取水,但是,當(dāng)測(cè)量的固體產(chǎn)品,會(huì)跟水起反應(yīng),或者有些粉末放在水里會(huì)漂浮,不能完全沉入,此時(shí)還用水來作為測(cè)量介質(zhì)的話,測(cè)量結(jié)果就會(huì)有偏差的,所以就需要用到固體密度計(jì)的溶液補(bǔ)償功能。
