«TRITON» MULTICHANNEL MAGNETIC FIELD MEASUREMENT SYSTEM

Up to 600 measurements per second with 0.1 nT resolution on each channel

Data acquisition unit of magnetic field measurement system
Data acquisition unit of magnetic field measurement system

Application:

- Automated real-time survey and magnetic field mapping
  of geomagnetic anomalies on the land and in the sea;

- Large-area demining: unexploded ordnance (UXO), landmine and seamine detection;

- Steel pipelines stressed state remote magnetic inspection.

Key features:

- High resolution 0.1 nT in wide ±70000,0 nT range;

- Up to 12x 3-axial sensors can be used simultaneously;

- Anyone topology of magnetic field sensor can be chosen
  from single fluxgate element to gradiometer or 3-axial topology;

- Making possible to provide magnetic measurements down to 40 meters under water;

- Real-time color map, linear graph and digital indication of measurements;

- USB/RS-232 interface to connect external GPS/RTK receiver;

- Connecting to the personal computer the system working as
  simple USB flash disk, since this no special driver required;

- Surfer-compatible measurements data format.

System architecture:

Price is composed from measurement system configuration:

1. Price of basic kit composed from 1 magnetic field sensor with acquisition unit,
    (with GPS-receiver built-in), 2 accumulators, charger, USB-to-PC data cable
    and sensor cable with up to 8 meter length is 4790$.

2. Each additional meter of sensor cable add to the price of 5$.

3. Acquisition unit can maintain up to 12 gradiometer and 3-axis sensors simultaneously.
3.1. Each additional gradiometer magnetic field sensor adds in the price of 550$.
3.2. Each additional 3-axis magnetic field sensor adds in the price of 680$.

4. Odometer on the base of incremental encoder adds in the price of 250$.

5. RTK system consists of receiver, base station with folding tripod
    and set of accumulators with charger adds in the price of 1100$.
