The DAQ-LP-CT4G wireless current acquisition sensor terminal is equipped with a low-power, high- sensitivity open-type transformer . It converts the large current on the primary side into a small current on the secondary side through the principle of electromagnetic induction, and is then used for current monitoring . It can sensitively detect the size of the line current and report data to the designated platform server wirelessly at regular intervals .

The terminal adopts GPRS/NB-IOT/LoRa communication mode to overcome the wireless communication obstruction caused by the special environment on site, greatly simplifying the on-site deployment time and reducing construction costs . The working status of the equipment is divided into three states: sleep , collection and storage , and activation and reporting . This terminal is equipped with a variety of open-close transformers, a wide range of measured current, high-quality magnetic core materials, an open-close structure, and is easy to install. It is used for current monitoring and collection in AC motors, lighting equipment, air compressors, heating, ventilation and air conditioning equipment, building automatic control systems, industrial city networks, rural power grid transformation projects and other scenarios .
