Thermal flow sensor that visualizes the amount and direction of thermal energy.
Energy flow
Thermal design starts with the measurement of thermal energy! Toyota Motor's thermal flow sensor 'Energy flow'
The heat flow sensor is a device that can easily measure heat flux, which is essential for elucidating the mechanisms of temperature change. By converting the electromotive force generated according to the temperature difference between the front and back of the sensor into heat flow, this sensor can measure the "amount" and "direction" of thermal energy passing through its surface with high precision and rapid response.
