Overview
High-precision wireless nodes for Vibrating Wire (VW) sensors, featuring built-in temperature compensation and pulse counting capabilities.
The Geolook Vibrating Wire (VW) Node series is the industry standard for wirelessly monitoring frequency-based geotechnical sensors. Designed to work with Piezometers, Strain Gauges, Crack Meters, and Pressure Cells, these nodes utilize advanced spectral analysis to deliver clean, noise-free readings even in electrically noisy construction environments. Unlike analogue signals which can degrade over long cables, the frequency signal from a VW sensor is immune to cable resistance changes. The Geolook Node preserves this signal integrity while adding the convenience of long-range LoRa wireless transmission, eliminating the need for manual data collection in hazardous or hard-to-reach locations.

Detailed Description
The VW Advantage
Vibrating Wire technology is the 'Gold Standard' in geotechnical monitoring because the output signal is a frequency, not a voltage. This means the reading is not affected by moisture in the cable or changes in lead wire resistance over long distances.
The Geolook Node excites the sensor wire by 'plucking' it with a voltage sweep, then listens to the resonant frequency. This method is incredibly stable and ideal for long-term projects like dam or tunnel monitoring.
S1 vs. S8: Strategic Deployment
We offer two models to suit different installation densities:
- BEAM-VW-S1: Designed for distributed monitoring, such as a series of single boreholes spread across a large site. It also features a unique 'Pulse Counter' input, allowing it to double as a rainfall or flow meter node.
- BEAM-VW-S8: The heavy lifter. It connects up to 8 VW sensors to a single radio. This is perfect for instrumented piles, multipoint extensometers, or strut levels where many sensors are clustered in one location, significantly reducing hardware costs.
Battery Life and Reliability
Power management is critical for buried or inaccessible nodes. By utilizing low-power components and smart sleep cycles, the BEAM-VW series can operate for up to 10 years on standard internal batteries (dependent on sampling rate). The IP67 enclosure ensures the internal electronics remain dry even during monsoon seasons or in humid tunnel environments.
Integrated Temperature Compensation
Almost all geotechnical structures expand and contract with temperature. To distinguish real movement from thermal expansion, temperature data is vital.
Every Geolook VW Node includes dedicated thermistor channels (one for every VW channel). This allows the system to automatically apply thermal correction factors to the raw data, ensuring the final engineering values are accurate regardless of the season.
Noise Filtering Algorithms
Construction sites are noisy places—both acoustically and electrically. Heavy machinery, generators, and power lines can induce interference in sensor cables.
The Geolook Nodes utilize proprietary signal processing algorithms to identify the pure resonant frequency of the sensor wire while rejecting background electrical noise, ensuring data integrity even in difficult urban environments.
