Claims (1)
- 測定セルがついている密度計を用いた試料の密度の正確な測定方法であって、前記測定セルは、
非常に良好な熱伝導性を持ち、その内側の部分でストッパ(11)によって閉じられた測定チャンバ(1)を規定する実質的な筺体と、
接地され、分析される前記試料で満たされ、前記測定チャンバ(1)の内部に延在するUチューブ(2)であって、該Uチューブ(2)は、その中間部で強磁性体部材(3)を備えた中央肢(21)と、それらの自由端で前記ストッパに固定され、前記測定チャンバ(1)から外側へ突出して、前記Uチューブ(2)内で分析される前記試料の注入と、該試料の排出とを可能にする2つの側方肢(22,23)とを有するUチューブと、
前記Uチューブ(2)と相対的に電位をもって維持され、キャパシタを規定するために前記チューブ(2)と面する位置で前記ストッパ(11)に固定された、絶縁された伝導性読み取り板(6)と、
前記強磁性体部材(3)と直角に前記筺体のハウジングに取り付けられた強磁性励磁巻き線(8)と、
前記巻き線を駆動するための手段と、前記キャパシタの容量を読み取るための手段と、
を備え、前記方法は、
分析される前記試料が前記Uチューブ(2)内に注入され、
前記巻き線を駆動するための手段が、前記Uチューブ(2)に連続的に同期した矩形励磁信号を伝送して、前記チューブに共振周波数で正弦波共振信号によって表わされる振動を引き起こさせるように、動作され、
前記共振周波数は、前記キャパシタ(2,6)の端子での電圧における変動から決定され、分析される前記試料の密度の近似値が、それ自体知られている標準方程式に基づいてそれから推論され、
前記矩形励磁信号のパルス幅は、前記共振信号の予め規定された一定振幅を維持するように制御され、分析される前記試料の粘性に依存する補正率がそれから推論され、
分析される前記試料の実際の密度が、前に決定された密度の近似値と前記補正率とに基づいて計算される、
試料の密度の正確な測定方法。
