摘要：
In order to provide a status monitoring system for accurately determining the contaminant water concentration in a lubricant oil used in a rolling device, the provision is made of a contaminant water concentration monitoring device (6) configured to monitor the contaminant water concentration in the lubricant oil (5). The contaminant water concentration monitoring device (6) includes an electrostatic capacitance detector (7) and an oil temperature measuring instrument (8), which are configured to detect the electrostatic capacitance and the oil temperature of the lubricant oil (5), respectively, and a water concentration calculation section (9) configured to detect the contaminant water concentration from the detected electrostatic capacitance and oil temperature in accordance with a predetermined rule.
