摘　　要：对在粮仓测温中使用的各种温度传感器做了一个比较全面的分析和比较。传统的温度传感器需要比较复杂的信号处理电路,而集成化温度传感器的外围电路非常简单,性能也是传统温度传感器所无法比拟的。粮仓测温的特点是所需要的传感器的数量大、传输线长和监测时间长。温度传感器的选择需要综合多种因素进行考虑。目前,还没有一种温度传感器可以完全替代其它的温度传感器。The temperature sensors used in the granary are analyzed and compared completely. The original temperature sensors need complicated signal process circuit. The integrated temperature sensors just need very sample circuit and the performance is much better than original sensors＇ performance. The feature of temperature measuring in granary is that it needs large quantity sensors and it has a long transmission line and a lone time monitor process. The selection of temperature sensor has to consider several kinds of factors. Now, any sensor can not take the place of other sensors completely.
