Assessment of materials for designing cables for monitoring temperature and humidity in stored grains

利用实测的相对湿度和温度可以计算仓内粮食的含水率。 IntraGrain开发了连接T和RH传感器的技术，并开发了解释测量的T和RH的软件。为了保护传感器免受恶劣的粮食储存环境的影响，传感器应安装在电缆内。拟议的研究旨在确定可用于电缆的合适材料。为了找到合适的材料，将测量所选材料在-40至60 ℃温度下的断裂强度、伸长率、收缩率。还将确定电缆材料内部传感器的响应时间。在研究结束时，将推荐使用温度（材料的最高和最低温度）和适当直径（以承受任何储存条件下的负载）。

Measured relative humidity (RH) and temperature (T) could be used to calculate grain moisture content inside stored grain bins. IntraGrain developed the technology to connect the T and RH sensors and software to interpret the measured T and RH. To protect the sensors from the harsh grain storage environment, the sensors should be installed inside cables. The proposed study is to determine suitable materials that could be used for the cable. To find the suitable materials, breaking strength, elongation, shrinkage of selected materials at temperatures from -40 to 60 C will be measured. The response time of the sensors inside cable materials will be also determined. Service temperature (maximum and minimum temperatures of the material) and suitable diameter (to withstand load under any storage condition) will be recommended at the end of the study.
