[KYB Corporation] "Oil Condition Diagnosis System" Service Launched - Supporting Optimal Maintenance of Hydraulic Equipment

KYB Corporation (hereinafter, KYB) has launched its "Oil Condition Diagnosis System" service, which constantly monitors the condition of hydraulic oil used in hydraulic equipment, supporting stable operation and efficient maintenance of facilities.

In recent years, various industrial sectors, including manufacturing, have been facing demands for advanced and efficient equipment maintenance due to aging facilities, a shortage of maintenance personnel, and the need to address SDGs and carbon neutrality. To address these challenges, KYB has developed an oil condition diagnosis system that visualizes oil conditions and enables understanding of equipment status.

Features of the Oil Condition Diagnosis System

This system is a service that combines an oil condition sensor, an IoT platform, and a dedicated web application to precisely measure the relative permittivity and conductivity of oil.

- **Real-time Visualization of Oil Condition** Constantly monitors the electrical properties of oil, namely conductivity and relative permittivity, as numerical values, allowing intuitive confirmation of oil condition on a web application.

- **High-Sensitivity, High-Reliability Sensing Technology** Particularly, highly sensitive measurement of conductivity is possible, contributing to early detection of subtle changes in oil condition.

- **Diagnosis Service Requiring No Specialized Knowledge** KYB constantly monitors data and notifies users with a report if abnormal signs are detected. This supports appropriate decision-making even if users do not have specialized knowledge of oil.

- **Data-Based Analysis in Combination with Property Analysis (Optional Service)** As an optional service, we offer evidence-based diagnosis and analysis in combination with oil property analysis services provided by our group companies.

### Target and Usage Scenes

This service is intended for factory equipment and various hydraulic machinery, with usage envisioned for the following applications:

- Condition monitoring of hydraulic oil in hydraulic equipment and test benches - Degradation management and optimization of hydraulic oil replacement timing - Reduction of sudden stoppage risks and advancement of predictive maintenance - Labor saving and efficiency improvement in maintenance operations

### Service Overview

- Service launch period: April 2026 - Service format: Monthly service combining an oil condition sensor, communication terminal, web application, and diagnosis service - Target market: Factory equipment, various hydraulic machinery sectors, etc.

*For details on service content, compatible models, costs, etc., please contact our sales representatives or our company.

### Future Development

Through the oil condition diagnosis system, KYB will contribute to stable equipment operation and maximization of lifecycle value, and will continue to expand its application to various industrial fields.
