ITD57L 温度变送器采用 PT100 传感器,带有不锈钢外壳,在零温度范围范围内使用专业 IC 电路,并实现全量程性能补偿。从而可以检测出广大监测点在广域网系统的实时数据,如液罐检测、储罐和油水温度监测等工业场自动化控制。
通过 LoRaWAN ® 模块,它通过网关将压力传输到网络服务器和应用程序服务器。用户可以远程监视状态。它适用于不同频率,如 470Mhz(中国)、868Mhz(欧洲)、915Mhz(美国)、923Mhz(澳大利亚)。与低功耗算法一样,内部电池一次充电可以工作1年以上(使用不同的参数,实现3年使用寿命)。
1) 1) 电池续航时间超过3年
2) -141dBm 灵敏度
3) 视图区域中的 10,000m 发射距离
4) 通过网关,它可以将数据上传到云中
5)可从事化工、冶金、石油、电力自动化领域
