Notice of Intent for use of Brand Name-GeoKon Pressure Transducers with LORA and Cellular Data Loggers

The GEOKON Model 8921 Series Data Loggers offer a high-value, LTE Cat 1 compatible, networked data collection solution for various vibrating wire instruments and digital sensors. These loggers are factory-ready for quick deployment and data acquisition. Sensor data is collected and transferred via a cellular network to a secure cloud-based storage platform, accessible through GEOKON Agent Software or exportable to third-party platforms via an Open API. The GEOKON API Portal facilitates commissioning, billing, and configuration, allowing users to activate loggers, change settings, configure channels, and view status. Available models include single and multichannel vibrating wire dataloggers, digital addressable data loggers, four-channel analog data loggers, tilt data loggers, and digital high-power data loggers for extensive sensor networks. Typical applications span groundwater monitoring, tailings dams, mining/slope stability, and structural monitoring of various infrastructures. Accessories like solar panels and cables are also available. The product specifications detail power supply, operating temperature, direct connection types, enclosure ratings, and specific details for vibrating wire, analog, and digital data logger capabilities.

The GEOKON Model 8910 GeoNet Wireless LoRa Data Acquisition System is designed for various monitoring applications including groundwater, tailings dams, mining, slope stability, and structural monitoring. This system utilizes LoRa radio technology in a star network topology, where data loggers communicate directly with a gateway. The data loggers conserve battery life by sleeping when not collecting or transmitting data and can operate autonomously if disconnected from the network. Up to eight networks can coexist using different operating channels, and the system supports LoRaWAN® protocol for third-party gateways. Network configuration is managed via the GEOKON API. The system includes a gateway that aggregates data from various data loggers and securely stores it in the GEOKON cloud platform, accessible through GEOKON Agent Software or a third-party platform via Open API. Available data logger models include single and multichannel Vibrating Wire, digital addressable, four-channel analog, tilt, and time domain reflectometry loggers, as well as a Digital High Power data logger capable of reading numerous MEMS sensors and non-GEOKON RS-485 MODBUS sensors with custom firmware. Accessories like solar panels and cables are also available. The system boasts a range of up to 20 km in rural areas and 5 km in urban areas, operates in the 868-928 MHz ISM band, and is housed in an IP68-rated enclosure.

Agent software and its mobile counterpart, Agent Mobile, provide comprehensive solutions for configuring hardware, monitoring sensors, and collecting data from GeoNet Data Hosting Systems and LC-2 Series Dataloggers. Agent Mobile, an Android application available on the Google Play Store, offers enhanced diagnostics, on-site data collection, and the ability to enable/disable GeoNet radio functions (Airplane Mode). The desktop Agent software simplifies hardware configuration, data monitoring, collection, and reduction, automatically converting raw data to engineering units using the GEOKON calibration database. It utilizes an object-oriented design with “Projects” to organize devices and allows for the creation of “Templates” to copy user configurations. Key features include an intuitive interface, comprehensive configuration options, real-time text and graphic-based monitoring, and data export capabilities to various formats with customizable alerts. The software is compatible with Microsoft Windows 7, 8, 10, or 11 and requires 1 GB of free RAM.

The GEOKON 4500 Series Vibrating Wire Piezometers and Pressure Transducers are advanced instruments designed for measuring fluid pressures in various geological and hydraulic applications. These devices operate on a principle involving a pressure-sensitive diaphragm and a vibrating wire, providing long-term stability, reliability, and resistance to environmental factors like moisture and varying cable resistances. The series includes models tailored for specific uses, such as standard installations, low-pressure measurements, small-diameter standpipes, drive-point applications, heavy-duty burial in embankments, and direct coupling into hydraulic/pneumatic lines. Additionally, specialized barometers and very low fluid pressure transducers are available. The instruments are constructed from all-stainless steel for corrosion resistance and can be customized with various cables, filter stones, and splice kits. They are compatible with a range of GEOKON readout devices and data loggers, making them suitable for federal government RFPs, federal grants, and state and local RFPs requiring precise and durable pressure monitoring solutions in challenging environments.
