New portable large sample Minispin

This is a development of the Minispin. It is a low-cost, high sensitivity portable slow-speed fluxgate magnetometer. It is of rugged construction, battery or mains-powered, and it may, therefore, be used either in the field or in the laboratory. Its performance in terms of noise level and convenience is better than the conventional laboratory instrument. Specimens are spun at 6 Hz about a vertical axis inside a triple-shielded, annulus-shaped fluxgate, the outputfrom which may be integrated over 6 or 24 seconds. The results are displayed as two orthogonal components of magnetization on a 6-digit liquid crystal panel. Integration is effected digitally and the magnitude and phases of the signal are extracted by Fourier analysis.

 

Portable large sample Minispin Specification:

Specimen size: 50 mm cube - 25 are supplied with the instrument.

Integration time: Either 6 seconds (24 spins), or 24 seconds(120 spins).

Sensitivity/Noise level: 3.5 x 10-8 EMU.CM-3 (3.5 x I 0-5 A/m) for 4 spins at the 24 sec's time constant.

Data output: On single 6-digit liquid crystal panel, with figures 8mm high. The display normally indicates the 'NORTH' component. The 'EAST' component is obtained by the press of a button. One (two) figures after the decimal point are indicated for 6 sec's (24 sec's integration time).The data is also available via an RS232 serial link that also controls the instrument. .A USB adaptor is available.

Range: 4 decade attenuator.

Power supply: : Battery or mains 240 or 110 V. The life of the batteries approx. 8 hours in continuous use. The batteries are rechargeable from 240/110 V mains or a 12 V car battery. The power consumption is 8 W.

Data processing: A serial interface is fitted inside the Minispin allows it to be controlled from a computer. The interface is a RS232, working at 4800 bauds. It controls the Minispin and passes the results back to the computer. If a notebook computer is used the kit becomes fully portable.

Programs: Programs are provided in Windows.
