| 摘要 |
Disclosed in the present invention is an apparatus to measure a temperature comprising: a plurality of temperature sensors which respectively configure separate channels; an analog-digital converting part to perform a digital conversion of measured values transmitted from the temperature sensors; a control measure which executes a PID operation by comparing the measured values transmitted from the analog-digital converting part with preset target values; and an outputting measure which transmits PWM control signals transmitted from the control measure to the outside. The control measure performs insulation among the temperature sensors by sequentially actuating input side insulating parts connected to each of the temperature sensors, and digitizes two times the measured values measured by each of the temperature sensors per every sampling period. |
