MESSKO® MTO
Oil level indicators for transformers
MESSKO® MTO oil level indicators are measuring devices with or without main switching contacts. They are especially well suited for fill level measurements in transformer oil conservators. There are two different float drive types with regard to the oil conservator: Float movement in radial or axial direction. The fill level indicator can be supplied with up to three micro-switches, either permanently installed or freely adjustable. The optional TT30 module enables analog and/or digital remote transmission of the oil level to the control cabinet or control room.
