전자유도법을 이용한 피스톤 온도 측정과 다구찌법을 이용한 코일 센서 검출법

Method of 'Electromagnetic Induction' has many benefits of other methods as 'Linkage Methode', 'Templog' and 'piston telemetry' etc. It is as precise as linkage method and as accurate as piston telemetry. In addition to that, It can measure multi points per piston and multi cylinders by real time. And we can save time and man power contrast to other method. But 'Electromagnetic Induction' method needs to calibrate each sensor parts, that takes place of many portion of preparatory period. In this paper we introduce calibration method which use 'Digital Variable Resistor'. If measurement equipment. primary & secondary coil sensor is prepared and some temperature sensor whose specification is known already is prepared too. you can prepare everything which is need to measuring piston temperature in very short period.
