Control of self-regulating heating cable for use in pipeline heating applications
J.L. Lardear · 2002
Self-regulating heating cable is an effective method of electrical heat tracing. The control of temperature without conventional sensors such as RTDs and thermocouples is described. The theory of temperature control using variable self-regulating cable is discussed. Characteristics unique to this method of heat tracing are detailed and a controller specified to meet these requirements. A cost-effective control system is described and laboratory results presented.>
