Multipoint temperature measurement system based on a film platinum temperature sensor |
|
| Abstract: | In the process of producing alcohol, the multipoint temperature in distilling towers needs to be measured. A multipoint temperature measurement system is designed by using a new type film platinum temperature sensor. The linearity correction circuit of positive feedback can make the output voltage be linear with the temperature, so the measurement accuracy of the system is improved. The system has such advantages as novel circuit design, high accuracy and good practicality. |
| Keywords: | temperature measurement multipoint film platinum temperature sensor linearity correction |
