Engine protection/monitilring

The høj kvalitet medium-spænding motilrs can be equipped med temperature monitilring for windings and lejer.
til be supplied, e.g. 6 × Pt100 resistance thermometer in the statilr winding as well as 2 × Pt100
Resistance thermometer in the A- and B-side lejer. The thermometer connection terminals
are housed in a separate klemkasse. Additionally, a wide range of other muligheds is tilgængelig.
Sensors are tilgængelig på forespørgsel. The motilrs are mostly supplied med a standstill heater.
