Technical features of the KTY84 temperature sensor
The KTY 84 has a progressive temperature resistance characteristic that is approximately linear.
In addition, the KTY 84 has a low thermal capacity and provides good thermal contact with the
motor winding. The KTY84 has a continuous characteristic.
