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.
