"Voice coil Temperature Meter" of Onsoku will electrically measure the temperature of the wire itself. Therefore, It is
possible to measure the electric wire original temperature without being affected by the thermal resistance of such an
insulating coating and the bobbin material.
ᲤᲴWhen measuring the temperature of the voice coil using a temperature sensor of contact type,
Thermal resistance of the insulating coating and adhesive, and measurement error of several tens of degrees is caused by heat radiation to the bobbin and the
outside air.
