IPD57L压力变送器,采用硅隔膜传感器或电容传感器,带不锈钢外壳,使用专业IC电路,温度范围为零,全量程性能补偿。因此,它可以检测出广大监测点中的网络系统实时数据,如液罐检测、储罐和油水压力监测仪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
