A data center in the U.S.is equipped with multiple standby diesel generator sets to cope with sudden power outages, in order to ensure uninterrupted power supply to data centers. These generator sets require regular maintenance checks, among which oil level monitoring is particularly important. Low oil level may cause engine damage or even shutdown, resulting in serious consequences.Therefore, oil level monitoring and low oil level alarm function is required to prevent generator set damage.

1.Installation location：A reed switch oil level sensor is installed in the oil pan or oil tank of each diesel generator set. According to the design requirements, the installation position, output signal and low liquid level alarm point position are selected.

2.Working principle: the sensor is connected to the reed switch through a magnetic float. As the oil level changes, the float moves up and down, and the built-in magnet changes the magnetic field strength around the reed switch accordingly, thereby controlling the opening and closing of the reed switch contacts. The oil level is monitored online, and when the oil level drops to the preset minimum safety limit, the reed switch closes and sends a switch signal to the monitoring system.

3.Monitoring and alarming: After receiving the signal from the reed switch fuel level sensor, the monitoring system can instantly display the current oil level status and automatically trigger the alarm mechanism when the oil level is too low, notifying maintenance personnel to replenish the oil in time to avoid engine failure caused by lack of oil.

1.Preventing failures：It ensures that the diesel generator set can start quickly and run stably in an emergency, effectively preventing equipment damage caused by insufficient oil level.

2.Automatic management: The product is integrated into the intelligent management system of the data center, it realizes remote monitoring and early warning of diesel generator sets, reduces manual intervention and improves operational efficiency.

3.Cost savings: Early warning avoids potential large-scale repair costs, while optimizing oil replenishment schedules and reducing unnecessary maintenance costs.
