温度的计量和监测在工农业生产和国民经济各部门具有重要意义和十分广泛的应用。而在温度的计量和监测中,要将温度信号转变为电信号则离不开温敏元器件和温度传感器。在测量过程中,由于温度的计测范围很宽,从极低温到极高温;每一种温敏元器件和温度传感器又具有各自的特点、适用范围和使用条件。因此,应根据实际使用时的不同要求适当地选
Temperature measurement and monitoring in industrial and agricultural production and various sectors of the national economy is of great significance and a very wide range of applications. In the temperature measurement and monitoring, it is necessary to convert the temperature signal into electrical signal can not do without temperature-sensitive components and temperature sensors. In the measurement process, as the temperature measurement range is very wide, from very low temperature to very high temperature; each temperature-sensing components and temperature sensors have their own characteristics, scope and conditions of use. Therefore, should be based on the actual use of the different requirements of the appropriate election
