JCM-1600 OIL MOISTURE SENSOR

Features

• Rapid continuous detection of water activity (aw) in oil
• Accurate water content in oil (ppm)
• Measure lubricating oil, hydraulic oil and insulation oil
• Multiple oil parameter calibration procedures
• Long-term stable operation in harsh environment

Summary

Real-time monitoring of moisture content in lubricating oils and hydraulic fluids plays an indispensable role in maintaining the proper operation of large-scale continuous operation equipment and heavy machinery. Moisture can compromise oil films, cause metal component corrosion, degrade lubricant effectiveness, shorten service life, and in severe cases, lead to unplanned mechanical shutdowns that result in serious safety incidents and economic losses.

As critical assets in the power industry, transformers and reactors rely on real-time monitoring of trace moisture content in insulating oil to ensure safe operation. Moisture accumulation reduces insulation breakdown voltage, increases dielectric loss, accelerates degradation of polymer-based insulation materials, and diminishes system performance. In severe cases, this can trigger insulation breakdown and partial discharge, ultimately compromising the safety of power systems.
