The present invention relates to a method of producing the sensors for monitoring corrosion of heat exchanger tubes in a thermal power plant. The sensor is made of the tubes taken out from actual heat-exchanger. As a result, the sensor not only has the same material as the actual heat-exchanger tubes, but also has the same surface state where it contacts the working medium. Therefore, a serious technical difficulties have been solved that the sensor made by the prior art can't measure different corrosion states of actual heat-exchanger tubes, that the corrosion rate measured is different from the corrosion rate of actual heat-exchanger tubes, and that the cost of anti-corrosive treatments is high . By use of the sensor made by the present invention, the different corrosion states of actual heat-exchanger tubes can be measured, not only the rate of uniform corrosion of actual heat-exchanger tubes can be measured but also the rate of localized corrosion of the heat-exchanger tubes can be measured. Moreover, the cost of treatment of anti-corrosion can be decreased.
