The magnetic oil level indicator in accordance with DIN 42569 is used for oil immersed transformers with expansion tank or reactors. They will be mounted onto the expansion tank. The transmission of float movement is done with a magnetic clutch. This guarantees tightness up to 10 bar. In case the view dome gets damaged, no oil can leak neither ambient air can enter unintentionally.
The magnetic oil level indicator according to DIN 42569 is distinguished in two types: Type A (without switches) und Type B (with one or two NO/NC limit switches).
