Abstract
A heater includes at least one resistive element. The at least one resistive element includes a material having a high temperature coefficient of resistance (TCR) such that the resistive element functions as a heater and as a temperature sensor, the resistive element being a material selected from the group consisting of greater than about 95% nickel, a nickel copper alloy, stainless steel, a molybdenum-nickel alloy, niobium, a nickel-iron alloy, tantalum, zirconium, tungsten, molybdenum, Nisil, and titanium. In one form, the heater is a tubular heater with compacted MgO insulation and a metal sheath.
