I?m responsible for Electrical Heat Tracing for Process Maintenance for an Offshore Platform. It is Type I process application for which loose temperature control is acceptable. Heat Tracing (by stabilized design self regulating cable) is intended just to maintain temperature above a set point. Process doesn?t care if temperature goes 10 or 15 degree higher.
In this case, please let know your opinion if process heating can be achieved using appropriately selected self regulating cable without any control temperature sensor and contactor. I believe the MCB to branch circuit will be always switched ON and only the current will be regulated based on temperature of process pipe. There is no need of any additional switching device or line temperature sensor.
Don?t have much experience with heat tracing. Just needed some advise to proceed.
