GDA16 Multipurpose Datalogger for Geotechnical Monitoring with 4G RS485 LoRa Bluetooth Communication
GDA16 Series Multipurpose Datalogger is a full-function data acquisition unit designed for long-term online monitoring projects. It adopts a stand-alone structure and integrates measurement, transmission and power supply in one compact unit. The aluminum alloy enclosure provides protection against water, dust, ultraviolet exposure and electromagnetic interference, making it suitable for outdoor engineering monitoring environments. The GDA16 Series supports flexible 1, 4, 8 and 16-channel configurations. Each channel can be used for multiple types of sensor signals, including vibrating wire, differential resistance, resistance, current, voltage, switch and digital output signals. Sensor channels can be freely combined, and different sensor types can be connected to the same unit according to the project requirements.
