This high-stability and high-resolution single axis fluxgate gradient sensor has a 1m separation between the sensing elements and an effective sensitivity of 0.03nT/m. The exceptional temperature stability of this sensor ensures minimal drift during surveys and reduces the need for adjustment. These sensors can be used on a handheld system, the Grad601, or can be easily mounted onto a cart for multi-sensor arrays.
The gradient sensor is housed in a rugged, lightweight 38mm-diameter enclosure which is fully sealed for operation under wet conditions. Two selectable ranges allow an increase in measuring range and resolution. An option for a higher bandwidth sensor is also available.
It can be integrated into specially designed Non-Magnetic Cart together with DL601 data loggers and a BC601 battery cassette, along with the necessary cables and acquisition software which can be provided.
