选用铂热电阻温度计时,应注意根据使用环境选择它的封装形式,否则会因测温元件的受潮短路而导致整个检测系统无法工作。在空气湿度大温度较低容易产生露点的场合(例如,冷冻站的测温、啤酒发酵罐测温等),为了避免露珠使热电光件短路,应选择玻璃、塑料或陶瓷封装的热电阻元件或铠装热电阻,以代替常用的云母骨架装配的铂热电
Use platinum thermistor thermometer, should pay attention to choose its package according to the use of the environment, otherwise it will be due to humidity components of the temperature measurement circuit caused by the entire detection system can not work. In the case of dew point prone to dew point when air temperature is low (eg, temperature in freezing station, temperature in beer fermenter, etc.), in order to avoid dewdrop short circuit of thermoelectric light, thermistor components of glass, plastic or ceramic package Or armored thermal resistance, instead of the commonly used mica skeleton assembly platinum thermoelectric
