Distributed Data Acquisition Node
The model LPWAN distributed data acquisition node is a multi-communication interface, multi-functional 4G wireless datalogger. This datalogger node has the advantages of multiple interface protocol conversion,automatic data collection, wireless distributed installation, easy maintenance, and high reliability. Suitable for data collection from various vibrating wire sensors and digital sensors, such as vibrating wire strain gauges, rebar strain gauges, load cells, crackmeters, earth pressure cells, piezometers/pore water pressure gauges, precise settlement monitoring system, displacement sensors, tiltmeter, inclinometer, temperature and humidity meter, rain gauge, etc. This datalogger can be widely used to collect and transmit structural health monitoring data in scenarios such as foundation pits, bridges, tunnels, slopes, reservoirs and dams, buildings, steel structures, and tailings ponds.
