Overview

Smart, portable readout with Bluetooth connectivity, GPS tagging, and real-time graphical data visualization.

The GL-VW200 represents the next generation of portable geotechnical data collection. Unlike traditional readouts, the GL-VW200 combines the precision of a vibrating wire interface with the power of a modern field computer. It features a full-color touchscreen, integrated GPS for location validation, and Bluetooth connectivity for syncing with mobile devices. Designed for large-scale projects, it allows engineers to upload project site plans, identify sensors via QR codes, and instantly view historical data trends in the field. It eliminates manual data entry errors and streamlines the "read-and-report" workflow.

Detailed Description

Advanced Operation & FFT

While standard readouts count zero-crossings to determine frequency, the GL-VW200 utilizes Fast Fourier Transform (FFT) signal processing . This allows it to isolate the true vibrating wire frequency from background electrical noise, making it superior for use near power lines, transformers, or active construction machinery.

The device also supports 'Project Mode,' where the user uploads a site map and sensor list. The readout then guides the engineer from sensor to sensor, ensuring no data points are missed during a survey.

Why Choose the GL-VW200?

Data Integrity: With built-in GPS and time-stamping, every reading is geographically verified, preventing data falsification or location mix-ups.
Instant Analysis: The ability to view a graph of the last 100 readings on-screen allows engineers to spot anomalies (like sudden movements) immediately while still on site, rather than waiting to return to the office.
Connectivity: Sync data directly to the Geolook Cloud via Wi-Fi or to your smartphone via Bluetooth, eliminating the need for physical cables and manual CSV exports.

Smart Applications

Automated Baseline Collection: Quickly establish initial readings for hundreds of sensors using the rapid-scan mode.
Multiplexer Control: Can connect to and control external multiplexers to read 16 or 32 sensors automatically via a single connection.
Remote Tech Support: Field technicians can share their screen via the companion app to get real-time troubleshooting advice from HQ.
