A high-temperature sensor, having at least one completely ceramic heater and at least one first sensor structure arranged on a first side of the completely ceramic heater, at least in areas. And a method for producing a sensor.

The present invention discloses an electric heating thermal management system for an oil and gas transportation pipeline based on renewable energy and CO.sub.2 energy storage. It transmits the feedback data value through a data collection device arranged in the pipeline to the early warning device by the control device. After analysis and processing, the early warning device can feed back the data value to the control device and the remote operation device in two modes. Different degrees of heating amount can be generated for the oil and gas transportation pipelines at different positions in different modes. Hierarchical and distributed management control for the oil and gas transportation pipelines can be targetedly conducted in unblocked, easily blocked and blocked positions of the oil and gas transportation pipeline. The present invention couples the renewable energy electricity supply device and the CO.sub.2 energy storage device.
