3.7.2.
Temperature measurement with KTY sensors:
Motor temperature can also be continuously monitored by the drive using a KTY 84-
130 thermal sensor built in to the stator winding. KTY sensors are semiconductor
sensors that change their resistance according to an approximately linear
characteristic. The required temperature limits for alarm and tripping can be set in the
drive.
The graph below shows KTY sensor resistance vs temperature, for a measuring
current of 2 mA:
Warning: KTY sensor is sensitive to electrostatic discharge. So,
always wear an antistatic wrist strap during KTY handling.
Warning: KTY sensor is polarized. Do not invert the wires.
Warning: KTY sensor is sensitive. Do not check it with an Ohmmeter or
any measuring or testing device.
