| Abstract: | The universal data acquisition system, which is based on PC and multiple - function ADC card, is widely used in the real - time measurement and control in industrial and scientific research. This paper discusses, first of all, the requirements of sensor - conditioning in the light of thermocouple temperature sensor, then the concept of transducer in comparison with the thermocouple temperature sensor and its transducer and, finally, a typical signal conditioning circuit for practical use to deal with the universal data conditioning functions. |
