System for calibrating temperature sensors of the platinum resistance type and permissible resistance type, which is able to acquire the data from 8 sensors at the same time through a data acquisition and conditioning electronic board and also acquiring the data from the high-precision reference pattern instrument via an electronic board of the serial type. The invention comprises a program based on Labview, which controls a temperature chamber through an electronic board with an optical protection system and which is able to maintain the temperature stable with small oscillations lower than ±0,01°C. The system is operated in an automated and sequential manner according to the configuration of the system, from 20,0°C to +60,0 °C with increases or reductions of 1,0°C. The system is flexible with regard to the configuration or programming of the sequence of calibration points. The calibration system is configured and the whole actions and measurements are performed in an automated manne r. The purpose of the system is to calibrate the temperature sensors for providing traceability to the measurements towards the primary patterns and reliability to said measurements.
