Definitions
- the invention relates to an electric heating cartridge, in particular for heating of liquid and / or gaseous media, with at least one PTC element, the two At least one PTC element associated electrode bodies, which in a relative to the electrode bodies by at least one insulating electrically isolated housing body received under a bias compressed are.
- Cartridges of this type are characterized by their small construction and thus, that they are both heating and temperature control at the same time.
- These Dual function is achieved through the use of PTC elements (Positive-Temperature-Coefficient), so-called PTC thermistors, achieved.
- a PTC element has the property only to heat up to a predetermined limit temperature. From this limit temperature The electrical resistance increases suddenly, so that the PTC element is not continues to heat. PTC elements are therefore self-regulating and require no additional Temperature control. It is possible to use PTC elements for different electrical To produce voltages and different limit temperatures.
