A Magnetic Oil Level Gauge (MOG) is an essential transformer accessory designed to monitor and display the insulating oil level inside the conservator tank of oil-filled transformers. Maintaining the correct oil level is critical for ensuring efficient cooling, proper insulation, and reliable transformer performance. A Magnetic Oil Level Gauge provides a clear visual indication of the oil level, allowing operators to monitor transformer conditions and identify abnormal oil level changes before they affect equipment performance.
The Magnetic Oil Level Gauge for Transformer operates through a magnetic float mechanism. As the oil level inside the conservator changes, the float moves accordingly. This movement is transferred magnetically to an external indicator dial, providing accurate oil level indication without direct mechanical contact. This design ensures dependable operation, reduced wear, and long service life even in demanding industrial environments.
Magnetic Oil Level Gauges are widely installed on power transformers, distribution transformers, furnace transformers, generator transformers, renewable energy transformers, and industrial oil-filled electrical equipment. They are suitable for both new transformer manufacturing and replacement during maintenance or refurbishment.
