<p>Provided are a sensor device that generates a quantitative signal and another qualitative signal which corresponds to pressure applied when pressure-applying matter, such as air, a liquid column or injection water poured or injected from a nozzle, collides (comes into contact), and a cooling system performance evaluation apparatus comprising same. According to the present invention, the generation of the quantitative as well as qualitative signals and data is enabled corresponding to the pressure applied when a liquid, air, liquid column from the nozzle, injection water from the nozzle, or the like collide (come into contact), and a measurement error caused by a change in temperature is prevented, based on which cooling system performance (in a pouring or injection state) can be evaluated with precision at least quantitatively. Therefore, maintainability and operability of a cooling system can be improved.</p> |
