Zusammenfassung:	A heater is provided that includes a resistance coil assembly defining a first end portion having a first conducting pin and a second end portion having a second conducting pin, and a resistance coil disposed between the first end portion and the second end portion, and a first zone adjacent the first end portion with a constant pitch. The resistance coil further defines a continuously variable pitch extending along a length of the resistance coil from the first zone to the second end portion. The continuously variable pitch provides a variable watt density such that a predetermined temperature profile is provided along the sheath.
