Figure 3 shows the characteristics by plotting the CA thermoelectric lamp output mV on the horizontal axis and the reciprocal of the sensitivity on the vertical axis. According to these results, the heat flow sensor according to the present invention has an extremely stable output. I know that it will happen.

In addition, the heat flow sensor devised by this invention not only has a stable output, but the reality is that surface-attached heat flow sensors have difficulties in how to attach them to the surface to be measured, but this sensor uses magnets. Since the magnetic adsorption force of the rubber sheet can be used, when the surface of the object to be measured is an iron plate, it becomes possible to bond with its own magnetic force, which is excellent in practical use.

As mentioned above, according to this invention, a planar thermopile made by photo-etching etc. is used as the thermopile, and the structure is such that the planar thermopile is simply sandwiched between thermal resistors, which greatly simplifies manufacturing. This has made it possible to significantly reduce costs, and since a part of the thermal resistor has magnetic force so that it has self-adsorption power,
It is possible to provide a heat flow sensor that can be bonded to a steel plate without using any other parts, and has practical advantages such as being able to perform highly accurate measurements.
