| Abstract: | Considering the fact that imperfection of platinum resistor-based temperature sensor can result in measurement error in data collection and transmission, a temperature acquisition system which boasting of hard- ware and software compensation calibration was proposed. Experimental results show that the high accuracy and resolution and strong anti-interference can make temperature error of this temperature acquisition system less than 0.05℃ ,and it can be applied to temperature measurement asking for high precision. |
