Z-Gradient Tension Band Magnetometer
The Z-gradient tension band magnetometer weighs 3.7 kg and features a folding mechanism for rapid deployment in confined survey areas. It operates with a 400 mm sensor baseline spacing between upper and lower fluxgate elements mounted on a rigid tension band framework. The measurement range spans ±3,000 nT with vertical gradient detection capability that captures magnetic field variations along the Z-axis. The device connects to rugged Android smartphones through the SENSYS GO application for real-time data recording and wireless export functions.
The system uses cesium vapor fluxgate sensor technology in a compact handheld configuration measuring approximately 1.2 meters in operational length. Data output integrates seamlessly with MAGNETO ARCH software for advanced processing alongside multi-channel systems like MXV3 and MXV4. The tension band design maintains fixed sensor separation during walking surveys across uneven terrain. The unit achieves setup and commissioning within 30 seconds through its collapsible carbon fiber frame structure. Battery life supports 8-hour continuous operation on rechargeable lithium-ion cells.
Military ordnance disposal teams deploy the Z-gradient tension band magnetometer for detecting unexploded bombs buried up to 4 meters in contaminated zones and former battlefields. Archaeological survey operations utilize the device for mapping historical settlements, fortification ditches, pottery kilns, and iron-age structures across narrow terrain corridors inaccessible to cart-based systems. Engineering corps employ the equipment for infrastructure reconnaissance before pipeline and highway construction projects. Geophysical consultants operate the system for mineral exploration and subsurface utility line mapping in restricted access areas.
Tactical Supply Pakistan provides field-ready detection systems that support critical operations across challenging survey environments.
What makes the Z-gradient configuration more effective than single-sensor magnetometers for shallow target detection?
The vertical gradient measurement subtracts Earth’s background magnetic field automatically, eliminating the need for base station corrections. This differential approach isolates localized anomalies while suppressing regional geological variations.
