Polarmoist是一款新型的、用于探测砂石骨料水分含量的光学湿度传感器。该传感器内嵌一个微处理器,并使用LED作为探测光源;水分含量则用骨料干基重量的百分比来表示。当将它安装在混凝土(制品)生产线的砂石骨料输送带或料仓喂料斗上时,可以对移动中的骨料进行含水率实时测量。该传感器属于非接触式的远端测量装置,故确保了传感器具有稳定的性能和更长的使用寿命。
Polarmoist is a new optical humidity sensor for detecting the moisture content of gravel aggregates. The sensor is embedded with a microprocessor and uses LEDs as the probe light source; the moisture content is expressed as a percentage of the dry weight of the aggregate. When it is installed on a gravel aggregate conveyor or hopper hopper in a concrete (product) line, real-time moisture content measurements can be made on moving aggregates. The sensor is a non-contact remote measurement device, thus ensuring the sensor has a stable performance and longer service life.
