Digital three-axis gradiometer
Product Overview
Grad-13 provides high resolution vector measurements of the strength and direction of magnetic fields on land or in water.
It features low orthogonality error and digital correction allow for scalar measurements to be made. It can use solo, or be integrated into multi-sensor arrays.
It’s ideal for site and downhole surveying, cable and pipe detection.
Key features
- Baselines from 500mm to 1000mm.
- Land and submersible (200m) versions.
- Measuring range of ±70 or ±100μT.
- Integral three-axis accelerometer with ±2g range.
- Individual sensor and gradient outputs.
- Gradiometer can be connected to a computer using readily available RS422 to USB or
- Ethernet converters.
- Gradient noise <25pTrms/√Hz/m at 1Hz with 500mm baseline.
Applications
- Detection of buried magnetic anomalies such as unexploded ordnance (UXO) by surface or downhole surveys.
- Geophysical surveys for archaeology and mineral exploration.
- Pipe and cable location.
