1) At the Ta (upper and lower) limits the hysteresis could deviate, for Ta > 130C the hysteresis is 30K -15K/+30K.
2) Details on request.
Note: The diagram for self-heating is measured with a thermal control without any insulation in an oil bath. Attention: The heating depends on the thermal conduction of the control to the equipment or part which should be protected.
