Abstract: 본발명은산업용설비나수송용으로사용할동안고저항성유체의품질과상태를판단하여결정하는방법에관한것이다. 상기방법은결정된주파수에서의전압신호의진동크기를적용하고, 유체에담겨진전극으로오프셋하고그리고, 신호에대한유체반응을정량화하는것이다. 상기방법은제로오프셋-전압을가진고- 및중간-주파수신호와오프셋-전압을가진저-주파수신호가인가된양호한 3개고정된전기적신호에대한유체의반응을관찰하는것이다. 고-주파수반응에서유체변화를변경하는것이중간- 및저-주파수반응에서변경하는것보다대체로덜한적용에서의유체용으로, 상기방법은제로-오프셋-전압신호인중간-주파수와, 비-제로-오프셋-전압신호인저-주파수만의반응을관찰할수 있다. 초기또는피크값에대한유체반응의변화크기와변화율이, 사용중에, 기본적이고연속적으로유체의품질과상태를결정하는데사용된다.

Abstract: A method for determining quality and condition of a highly resistive fluid in transportation and industrial equipment. The method applies a multitude of oscillating voltage signals at determined frequencies and offsets to electrodes immersed in the fluid and quantifies fluid response to the signals. The method monitors response of the fluid to a preferred three fixed electrical signals applied a high and a medium frequency signal with zero offset voltage and a low frequency signal with an offset voltage. For fluids in applications where change in the fluid's change in high-frequency response is substantially less than changes in medium- and low-frequency responses, the method can monitor response to only the medium-frequency, zero-offset- voltage signal and the low-frequency, non-zero-offset-voltage signal. The magnitude and rate of change of fluid responses, relative to initial or peak values, are used to essentially continuously determine fluid quality and condition while in use.
