Tubular heating element

In the production process of the ceramic heating elements, a ceramic film with an imprinted conducting path is linked with the ceramic carrier material via a so-called laminating process. In the subsequent firing process the sintering into a monolithic component takes place. By integration into the alumina body, the platinum conducting path is protected from the ambient atmosphere and electrically insulated to the in-and outside. Thus, the heating elements are extremely resistant to oxidation and corrosion, durable and robust. Standard heating elements have proofed their durability over more than 100,000 heating cycles (heating and cooling for two minutes each). Due to the compact design, precise heating is possible, specifically where the heat is needed. The ceramic heating elements are deployable in continuous or alternating operation up to 1100 ° C and for a short time up to 1300 ° C. With thin-walled geometries, heating rates of up to 1000 K / min are possible High temperature heating elements A major advantage offered by the platinum conductor path is the linear resistance depending on the temperature. As a result, the heater can simultaneously serve as a temperature sensor and the current operating temperature can be determined at any time. Another advantage is the infinitely variable controllability of the heater temperature via the voltage, from room temperature to the maximum temperature. In addition to determining the temperature via the resistance of the heating circuit, it is optionally possible to design it with an additional sensor circuit.
