Aiming at the problem of low temperature measurement precision.a high precision temperature measurement
system was put forward based on the PTIOO platinum resistance temperature sensor. This paper introduced the principle
of platinum resistance measuring temperature; Designed a four wire system of platinum resistance connection circuit;
Designed the circuit which could reduce the interference; The accuracy of measurement was improved by joining in the
software compensation value method. Experimental results show that the system can realize high precision temperature
measurement and has good stability, this system can be applied to most of the production situations of temperature
measurement. and it is also easy to operate and has high precision. |
