Designed by Shanghai Zhichuan Electronic Tech Co., Ltd., ZCT330MX‐SWP‐N‐YK is a high‐precision dual‐axis inclinometer using NB‐IoT technology for communication. The device measures tilt along each axis from -30 to +30 degrees with a resolution of 0.001 degrees. The device sends an alarm to the platform via the NB-IoT network when the tilt angle of the monitored object exceeds a certain preset value. The critical tilt angle can be set over the entire measuring range with an accuracy of 0.001 degree. The default protocol is CTIOT (based on China Telecom platform), while MQTT and COAP (connectable to One net platform) are optional. The model can be widely used in geotechnical and structural health monitoring, municipal administration, telecom, public utility and many other areas.
