| Abstract: | A kind of heat transfer coefficient sensor based on steady state method was developed.A calibration terminal was pulled.The precision was analyzed and the results were compared with the values calculated from the classics empirical equation.The heat transfer coefficient obtained from the calibration terminal and the empirical equation is in a good agreement.The results shows that the calibration method is reasonable.The feasibility of the sensor is proved by the calibration experiment and the modified coeff... |
