Description

Insert these thin, laminated RTDs in winding slots to detect high temperatures before insulation damage occurs. Six sensors are recommended for each motor, two per phase. Locate sensors near the hottest point of the windings for best performance.

RTD (Stator Slot RTD) of TOPE601 series is installed and coated in additional housing, consisting of two parts (lower and upper). With the additional housing, complete thermometer can be precisely adapted to the dimensions of the generator groove.

Dimensions of the housing, length and insulation of the connecting cable, may be selected depending on the application needs/requirements


Unique design of a core with wound wire


In our sensors, we use a unique method of bifilar winding, so that wire does not “break” on the edges of specially prepared core. It makes out thermometers almost completely resistant to corona discharge or other sudden transients of power.


Other versions


Above mentioned data presents only small part of our supplies program of stator temperature sensors. Upon the customer's request, other versions can also be delivered.
