THE TECHNOLOGY:


Three basic types of element can be produced, which the company refers to as Types 1, 2 and 3:

Type 1 Elements - Here the resistive track is flame sprayed directly onto an insulating substrate and electrical contacts are applied at two opposing points, or areas, so that the current flows from one contact area to the second, through the resistive oxide matrix, along the surface of the substrate, and generates heat from the resistance of the oxide matrix to the passage of electrical current.

Type 2 Elements – transmit current in the z axis through the substrate rather than radially across one face of it, as is the case with Type 1 elements. As such, there is no insulating layer between the element and the substrate.

Type 3 Elements – are also being developed. These are self-regulating elements, which can be produced with “switch points” ranging from 40°C to 400°C without the need for a separate thermostat or temperature regulating device. They are essentially modified Type 2 elements, but incorporating an additional oxide layer, providing a system with two resistors in series. Please contact us if you wish to discuss these.

For Type 1 Elements the current flows from one contact area to the second, through the resistive oxide matrix, along the surface of (but not through) the substrate.
