Bộ thu thập và lưu trữ dữ liệu Datalogger cho cảm biến dây rung (GeoNet Cellular, Wi-Fi® + Satellite Network Loggers) Geokon 8920 - 8930 - 8950
Overview
The Model 8920 Series Cellular Loggers, Model 8930 Series Wi-Fi Loggers and Model 8950 Series Satellite Loggers offer high-value, networked data collection options for all GEOKON vibrating wire instruments and addressable sensor strings.¹ The 8920 and 8950 Series loggers are ideal for smaller networks with a limited number of sensors, high-traffic areas (i.e. areas with radio interference), dense urban environments and areas with no line-of-sight between loggers. The 8930 Series loggers are ideal for underground mines, indoor environments and on structures with a Wi-Fi network readily available.
The GeoNet Network Loggers can be added to sites with existing GeoNet 8800 Series and/or GeoNet 8900 Series Wireless Data Hosting Systems, allowing additional loggers to be placed in locations beyond the range of existing mesh networks. The loggers are ready for deployment and data acquisition may commence within minutes after installation as no SIM card nor cellular provider activation are necessary.²
The system is compatible with all GEOKON Vibrating Wire instruments, addressable sensor strings and addressable thermistor strings. Single, multichannel and addressable versions of each telemetry option are available. Self-contained tilt loggers are also available, for attachment to structures, to wirelessly measure any tilting that may occur. The multichannel VW loggers expand the capacity at each logger, allowing clusters of closely spaced sensors or vibrating wire load cells, multipoint borehole extensometers or multilevel piezometers to be added to the system.
The GeoNet Network Loggers collect their respective sensor data and provide seamless and secure cloud integration via the Internet and GEOKON OpenAPI. GEOKON OpenAPI is easy-to-use and allows users to activate loggers, change settings, configure sensor channels, and view current logger status. Industry leading data visualization software or the no-cost GEOKON Agent Software can be used with GEOKON OpenAPI for data viewing and reporting.
The capacity of GeoNet Multi-Channel and Addressable Loggers can be expanded using the Model 8960 Series Digital Vibrating Wire Interfaces.
