The temperature block calibratior ranges from 50℃ to 300℃,and the Immersion depth is only 45 mm. The heat method is dependent on ANSYS,which simulate the temperature field. The calibratior is heated by a 500 W heater and six 25 W heat rods. Through the dynamic PID control technology,effectively control temperature overshoot phenomenon. After all,the temperature block calibratior can meet the demand of calibrating short temperature sensor in field environment,since the high heating and high cooling,stability and radial uniformity.
