Embodiment Construction
[0050] The technical solution of this patent will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0051] A kind of wireless real-time temperature measuring device of the present invention, such as Figure 11 As shown, it includes a conductive coil 2 and a Hall sensor 33;
[0052] The Hall sensor 33 is located within the range of the magnetic field generated by the conduction coil 2, and the best position is at the center of the axis of the conduction coil 2;
[0053] The conductive coil 2 is located in the temperature field. For the conductive coil 2 using different metals, the change in resistance value is different for every degree of temperature change. Under constant voltage, the change in resistance value can be converted into the change in current according to Ohm’s law. According to Biot-Savart’s law The change of the current can be converted into the change of the magnetic field strength, therefore, the m...
