Method and apparatus for high quality of the resistance of the fluid and / or the state of the online monitoring

摘要

Method for monitoring the fluid electrically resistive highly lubricant or motor oil, applying an AC electrical potential across the fluid in the DC offset and the first frequency of the first electrical response of the first to obtain The resulting a step for, and measuring the electrical response obtained first, the electrical response of the second frequency of the second 2, DC offset of the second to the DC offset voltage of the first non-zero or by applying an AC electrical potential across the fluid a combination thereof, respectively, different from the DC offset of the first and second frequency, comprising the steps, DC offset and the first frequency of the first and second resulting It includes a step of measuring the electrical response, and a step of analyzing the state and / or quality of the fluid from the electrical responses of the first and second measured for the electric potential applied in the respective first and second .
