How to detect the quality of inductance hollow coil
For the detection of the quality of air core inductance coil, we should first see whether the appearance of inductance coil is broken, whether the coil is loose, and whether the line is arranged in a whole column.
If there is no obvious damage on the appearance, it needs to be detected by inductor. Generally, the inductance of inductance coil is directly related to the thickness and number of turns of enameled wire used in inductance coil; The resistance value of the inductance coil is not only related to the thickness of the enamelled wire, but also directly related to the test room temperature. Generally, the constant temperature environment will be selected to measure the resistance value of the inductance coil, which will be more accurate.
