MESSKO® OLS
Oil level switch
Do you see potential for improvement in your existing oil level switches? Then MESSKO® OLS is your solution. The advanced oil level switch with integrated float technology ensures accurate monitoring of oil levels in your transformers. Even if gas accumulates under the cover, the measurement accuracy remains unaffected.
MESSKO® OLS is particularly suitable for use in wind power applications, due to its high corrosion resistance. It has passed the tests, which were carried out in accordance with IEC 60076-22-1 standard. To protect the sensitive floating system from fluid waves inside the transformer and from damage during installation, it is covered with a plastic tube. There is a test point or a screw option for venting the system.
The device can be easily screwed into the transformer using a G 1½ inch thread. A highlight of the design is the terminal box, which can be rotated 360° by hand from the customer.
