Abstract
A heating device for a field-device display module includes a heating element. The heating element is adapted to the shape of the field-device display module and is equipped such that it converts an electrical current to thermal energy. The heating element can be coupled to the field-device display module such that by the heating element the field-device display module can be heated.
Claims23
A heating device for a field-device display module, comprising:
- a heating element adapted to a shape of the field-device display module, the heating element converting an electrical current to a thermal energy,
- wherein the heating element is couplable to the field-device display module so that, by the heating element, the field-device display module is heatable.
A heating arrangement for a field-device display module, comprising:
- a heating device including a heating element adapted to a shape of the field-device display module, the heating element converting an electrical current to a thermal energy, the heating element being couplable to the field-device display module so that, by the heating element, the field-device display module is heatable;
- and
- a heating-element control device controling the current for the heating element so that a specifiable thermal energy is supplyable to the field-device display module.
A method for displaying a measured value on a field-device display module, comprising:
- switching a heating arrangement on;
- heating the field-device display module;
- and displaying the measured value.
