The oil level indicators of our MTO-TT30 Series are equipped with the same features of our well known MTO-Series.

Furthermore, the TT30-module enables the analogue (0....1mA; 0....20mA; 4....20mA) and digital (RS485) remote indication of the liquid level into the transformer cabinet or the control room.
For visualization of the 4....20mA signal you may use the Ei100 or El100/160 electrical display.
