STATUS MONITORING SYSTEM AND STATUS MONITORING METHOD FOR ROLLING DEVICE
First Claim
1. A status monitoring system to monitor a status of a rolling device, comprising:
- a contaminant water concentration monitoring device to monitor a contaminant water concentration in a lubricant oil, the contaminant water concentration monitoring device including;
an electrostatic capacitance detector to detect an electrostatic capacitance in the lubricant oil;
an oil temperature measuring instrument to detect an oil temperature in the lubricant oil; and
a water concentration calculation section to detect the contaminant water concentration in accordance with a predetermined rule from the electrostatic capacitance detected by the electrostatic capacitance detector and the oil temperature detected by the oil temperature measuring instrument.
