了解温度传感器一、了解温度传感器Understandingtemperaturesensors因此，人类离不开温度，当然也离不开温度传感器。Therefore,humanbeingscannotlivewithouttemperature,andofcoursecannotlivewithouttemperaturesensors.温度是反映物体冷热状态的物理参数。Temperatureisaphysicalparameterthatreflectsthecoldandhotstateofanobject.温度是与人类生活息息相关的物理量。在2000多年前，就开始为检测温度进行了各种努力，并开始使用温度传感器检测温度。人类社会中，工业、农业、商业、科研、国防、医学及环保等部门都与温度有着密切的关系。工业生产自动化流程,温度测量点要占全部测量点的一半左右。Temperatureisaphysicalquantitycloselyrelatedtohumanlife.Morethan2,000yearsago,variouseffortstodetecttemperaturebegan,andtemperaturesensorsbegantobeusedtodetecttemperature.Inhumansociety,industry,agriculture,commerce,scientificresearch,nationaldefense,medicineandenvironmentalprotectionandothersectorshaveacloserelationshipwithtemperature.Intheindustrialproductionautomationprocess,thetemperaturemeasurementpointsshouldaccountforabouthalfofthetotalmeasurementpoints.
