MESSKO^® MMK

Messko products for transformers ensure a high degree of measuring quality and reliability. Finding simple, practical solutions is frequently required when transformers in operation are to be upgraded and retrofitted.

In the area of oil level indicators for transformers, our type MMK oil level indicator works without a float in the oil conservator and can be easily mounted on existing connections in accordance with DIN 42552.

A measuring pipe of stainless steel is secured as a parallel container with a flange to the oil conservator. This pipe contains a cylindrical float with a built-in permanent magnet.

The indicator rail with the magnetic flags is installed on the outside of the measuring pipe. The float magnet turns the magnetic flags in the indicator rail by 180° depending on the filling level. From white to red for rising level and from red to white for sinking level.

Extremely flexible use for various applications due to modular kit system consisting of:

• Connection fittings in acc. w. DIN 42552
• Indicator rail, mounting terminals
• Float
• Measuring pipe
• Limit value switch
• Remote control of measured values

The type MMK indicator is also available as a complete unit based on customer specifications.

Advantages of the MMK solution:

• Easy to upgrade
• Good legibility
• Shock-proof design
• Weather-resistant
• Vibration and oscillation-proof
• Limit value contacts (min. - max.)
• Remote transmission (4 to 20 mA)
• Low maintenance requirements
