«TRITON» MULTICHANNEL MAGNETIC FIELD MEASUREMENT SYSTEM
Up to 500 3-component measurements per second with up to 0.1 nT resolution
Application:
- Automated real-time survey and magnetic field mapping
of geomagnetic anomalies on the land and in the sea;
- Searching and tracing the underground communications;
- Geomagnetic field inverse problem solution;
- Multichannel geomagnetic station;
- Steel pipelines stressed state remote inspection and monitoring.
Key features:
- High resolution from 1.0 nT to 0.1 nT (optionally);
- Wide ±70 000 nT or ±180 000 nT (optionally) measurement range;
- Up to 12x 3-component sensors can be used simultaneously;
- Sensors networking at distances up to 2 km and more;
- Can be mounted on the UAV and optionally equipped by special radio channel with
up to 40 km radius of action in order to acquire data remotely from UAV mounted
sensor system to the ground placed acquisition station in real time;
- Anyone topology of magnetic field sensor can be chosen from
single fluxgate element to gradiometer or 3-component topology;
- Making possible to provide magnetic measurements down to 1 km under water;
- USB/RS-232 interface to connect custom GNSS receiver, or RTK system,
or sea radar (e.g. Trimble R8, Emlid Reach RS+, Lowrance Elite-7 Ti, etc.);
- Real-time color map, linear graph and digital indication of measurements;
- Being connected to the personal computer the Triton system works
like a standard USB flash drive, does not require any software driver;
- Output data format compatible with Surfer and Google Earth.
System architecture:
Price is composed from measurement system configuration:
1. Price of basic kit composed from 1 magnetic field sensor with acquisition unit,
(with GNSS receiver built-in), 2 accumulators, charger, USB-to-PC data cable
and sensor cable with up to 8 meter length is 4790$.
2. Each additional meter of sensor cable add to the price of 60$.
3. Acquisition unit can maintain up to 12 gradiometer and 3-component sensors simultaneously.
3.1. Each additional gradiometer magnetic field sensor adds in the price of 550$.
3.2. Each additional 3-component magnetic field sensor adds in the price of 690$.
4. Odometer on the base of incremental encoder adds in the price of 250$.
5. RTK system consists of receiver, base station with folding tripod
and set of accumulators with charger adds in the price of 3200$.
