Nearline-PM for the Energy Industry
Wireless Network Vibration Sensor System "Nearline-PM" [Enables proactive measures before failures by predicting equipment abnormalities]
No wiring work required, easy to install later. Achieve equipment maintenance at a low cost.
In the energy industry's equipment maintenance, stable operation of plants is crucial. In particular, failures of rotating machines such as motors, pumps, fans, and compressors can lead to losses due to operational downtime and decreased safety. Nearline-PM continuously monitors the vibrations of these facilities, enabling early detection of failure signs and allowing for planned maintenance. This contributes to stable operation of equipment and reduction of maintenance costs. 【Usage Scenarios】 - Power plants - Substations - Oil plants - Gas plants 【Benefits of Implementation】 - Reduced risk of unexpected equipment shutdowns - Lower maintenance costs - Extended equipment lifespan

basic information
**Features** - Utilizes battery-operated wireless sensors, eliminating the need for wiring work. - Allows for near-constant monitoring with automatic measurements once a day (measurement frequency can be set as desired). - Can be retrofitted, making it suitable for small-scale starts. - Supports high frequencies (17kHz) to detect initial abnormalities in bearings. - Despite being a compact sensor, it is designed for a long battery life of approximately 5 years. **Our Strengths** Asahi Kasei Engineering Corporation provides consistent engineering services from design and construction to maintenance. We also develop diagnostic equipment utilizing digital technology. In addition to offering vibration sensors, our engineers, who have been involved in actual vibration diagnostics, provide support based on how equipment is used and common points of confusion in decision-making. Recently, we have also started vibration monitoring and diagnostic services for ships, with engineers holding ISO 18436-compliant vibration diagnosis qualifications. We hope to be a resource you remember when questions arise, such as: "How should I consider this case?" "Is the current monitoring method sufficient?"
