Stevens Smart PT 是一款陶瓷膜气压和温度传感器,提供精确的测量结果,适用于各种液位测量应用。除瞬时测量简单之外,这款智能传感器还能捕捉峰值液位,自动采样并按照一定的时间间隔报送基本数据,时间间隔可设置。
耐腐蚀不锈钢外壳和密封的电子元件,使 Smart PT 非常持久耐用,应用时可长期置于水中。
Smart PT 适用于开口型或绝对压力传感模块。两种型号均可根据用户指定长度配备开口型线缆。通过通风管提供大气参数,对气压变化进行补偿。
对地球引力场的局部变化进行可编程式的校正,此外Smart PT 还可对水温-密度相关性进行自动补偿。
每一款 Smart PT 都提供 SDI-12 和 RS-485 两种数字界面。与现有电源和数据采集一起兼容,易部署,方便远程监测站使用传感器进行数据收集。
eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
