Influence of Ambient Temperature on Measurement Results of Wireless Pressure Data Logger
Pressure wireless data recorder is widely used in medical,food,medicine,biotechnology and other fields as the verification equipment of thermal sterilization effect.Because the accuracy of its quantity value will di-rectly affect the effectiveness of sterilization,the calibration is mainly carried out at room temperature in China at present,which is quite different from the actual use environment of more than 100℃.Therefore,according to JJF 2095-2024 calibration specification,this paper conducts comparative experiments on different pressure values at normal temperature,121 ℃ and 134℃.The results show that the pressure value of the recorder at normal tempera-ture is very different from that at 121℃ and 134℃,that is,the ambient temperature has a great influence on the measurement results.
