ABSTRACT:
A strip heater (10) having at least one elongate control element (12a), at least one elongate heating element (12b) and a plurality of elongate conductors (14). An electrical insulator (18) partially encloses the elements (12) and the conductors (14). The elements (12) are physically separated and electrically connected by one of the conductors (14) such that both of the elements (12a and 12b) can be simultaneously placed in relative thermal contact with an object to be heated (19). An equally preferred alternate embodiment (310) has a dividing strip separating further separating the heating element (12b) from the control element (12a) and at a fixed distance such that the heating element (12b) is maintained generally parallel to the control element (12a).
