Automatic Data Logger

Product Model:
BGK-Micro-40Pro
Application scope:

BGK-Micro-40Pro series automatic data logger is a new product developed based on IoT technology. It supports three measurement modes: fixed-point, equal interval, and threshold trigger. Measurement data can be transmitted to the G-cloud platform (or BGKLogger) via 4G, LAN, or WIFI, or through RS485 local networking. It can be widely used for automated monitoring in various applications such as water conservancy, geological disasters, highways, bridges, slopes, and subways.

Product Introduction

BGK-Micro-40Pro series automatic data logger is a new product developed based on IoT technology. It supports three measurement modes: fixed-point, equal interval, and threshold trigger. Measurement data can be transmitted to the G-cloud platform (or BGKLogger) via 4G, LAN, or WIFI, or through RS485 local networking. It can be widely used for automated monitoring in various applications such as water conservancy, geological disasters, highways, bridges, slopes, and subways. BGK-Micro-40Pro can achieve measurement on up to 40 channels, with each channel capable of acquiring data from various types of sensors including vibrating wire, differential resistance, standard voltage/current signals, resistance type, linear potentiometer type, and digital sensors. It can also measure a single tipping-bucket rain gauge.

BGK-Micro-40Pro-VW model automatic data logger can achieve measurement on up to 40 channels for vibrating wire instruments. The BGK-Micro-40Pro-R8/R16 models feature a 2U chassis design, suitable for standard equipment racks.

The supporting system software integrates user management, measurement management, data management, and communication management, providing support for automated measurement and data processing for engineering safety. The power supply, communication interfaces, and each measurement channel of the automatic data acquisition unit feature lightning protection, complying with national and relevant industry standards.
