11.3 ΔT functionality
This functionality is used if the temperatures in a workpiece must not differ too much in order to
avoid stresses in the material. The functionality is also used for bearings when the temperatures of
the inner ring and outer ring must not differ too much. If necessary, ask the supplier of the workpiece
what the maximum temperature difference in the workpiece may be.
The ΔT functionality is switched on and set as described in section 6.5.
For the ΔT functionality it is necessary that the two sensors (T1 and T2) are connected to the heater
and positioned correctly on the workpiece.
Positioning of sensors:
Position sensor T1 (red) at the point where the heat is applied to the workpiece; this is usually the
bore. This sensor is the "main sensor" and the master in the heating process. Position sensor T2
(green) elsewhere on the workpiece. Position it in such a way that it is easy to monitor a possible
difference in temperature between the two measuring points on the workpiece. See also the
image in chapter 7.
