智能型在線式側(cè)裝密度計的溫度補償該怎么算
密度計的溫度補償并不是說補償?shù)蕉嗌龠m合，而是要按照測量時實際的情況來補償?shù)?，并不是說想補多少就補多少。
密度計的溫度補償原理是：使用水當測量溶液時，密度計能測得樣品對水之比重值，而水的比重會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)加以溫度補償。
對于水的溫度補償系數(shù),儀特諾固體密度計系列產(chǎn)品型號，都已存入攝氏0~49℃的記憶值。

/主要特點
1、采用一體化結(jié)構(gòu)的兩線制變送器，無活動部件維護簡單。
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、溫度和密度兩個參數(shù)可交替顯示，便于進行行業(yè)標密換算。
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.
測試前用溫度計量出水的實際溫度之后，將相應溫度修改成溫度計所顯示之溫度即可。(水溫相差6℃則比重將相差0.001)。儀特諾密度計儀器出廠時機器默認溫度為25℃。
運用阿基米德原理浮力法測固體密度，用純水作為測量介質(zhì)，既經(jīng)濟實惠，又方便取水，但是，當測量的固體產(chǎn)品，會跟水起反應，或者有些粉末放在水里會漂浮，不能完全沉入，此時還用水來作為測量介質(zhì)的話，測量結(jié)果就會有偏差的，所以就需要用到固體密度計的溶液補償功能。

1、在線密度計傳感器部分間距最少為200mm,直徑為50mm, 現(xiàn)場不能小于這些尺寸安裝,如選擇彎曲型密度計,請測量好可以伸進管內(nèi)的法蘭和長度尺寸。
1. The distance between the sensors of the on-line densitometer shall be at least 200 mm and the diameter shall be 50 mm, which shall not be less than these dimensions for installation on site. If the bending densitometer is selected, please measure the flange and length that can be extended into the pipe.
2、現(xiàn)場液體必須保持沒過兩個測量傳感器,法蘭到第一個傳感器的距離可選。
2. The liquid in the field must not exceed two measuring sensors, and the distance from the flange to the first sensor is optional.
3、管道安裝時需讓液體從最下面?zhèn)鞲衅髦逻M入液體，或者從最上面?zhèn)鞲衅鞯纳厦孢M入液體，不要從中間進入液體。管道安裝通液體時，管道閥門或者彎頭部分至少留出30CM液體緩沖距離。
3. When installing the pipeline, the liquid shall be allowed to enter the liquid from the bottom of the sensor or from the top of the sensor. Do not enter the liquid from the middle. When the pipeline is installed with liquid, at least 30cm liquid buffer distance shall be reserved for the valve or elbow part of the pipeline.
4、配備電源為24VDC輸出4-20mA信號如需接二次用表，需接24V“+”
4. Equipped with 24VDC output 4-20mA signal, if it needs to be connected with secondary meter, it needs to be connected with 24V "+"
5、現(xiàn)場環(huán)境如果外部有腐蝕性液體，請做好防護措施。如果有雷擊危險，請在周圍做好引地裝置。
5. If there is corrosive liquid outside the site environment, please take protective measures. If there is a risk of lightning stroke, please make a grounding device around.
6、如需拆卸做清洗時，拆裝時請保證傳感器膜片不受到碰撞及其它損壞。
6. If it needs to be disassembled for cleaning, please make sure that the sensor diaphragm is not damaged by collision and other damages during disassembly.
7、請勿在高出5Mpa情況下使用。
7. Do not use above 5MPa.
8、如果需要調(diào)整量程需要用手持器, 技術(shù)問題請聯(lián)系華恒.
8. If you need to adjust the measuring range with a handheld device, please contact Hua Heng for technical questions
