The Smart Fieldmeter_Digital (SFD) electromagnetic field monitor are battery-operated instrument/data loggers from Westek Electronics capable of 55 hours measurement operation with primary or rechargeable cells. The standard SFD electromagnetic field monitor is supplied with probes selectable from three isotropic models (0.2MHz - 3GHz; 2MHz - 12.5GHz; 3MHz - 18GHz). The new Smart Fieldmeter probes, model PI-01E, have an extensive field strength range of 0.3 to 600 volts/metre and utilize a tri-axial isotropic diode as sensing element, which together with correction factors, provides a virtually flat frequency response of less than ± 1.5 dB from 100 kHz to 6 GHz. Rotational isotropicity is less than 1 dB.
The SFD electromagnetic field monitors employ a powerful data processor with data storage on removable flash memory data storage cards (MMC compatible) capable of typically storing data files of 100,000 points with a total capacity of 999 data files. Format is in text readable by Excel or Word. An adjustable threshold and 2 kHz buzzer operating on instant or average values provides an invaluable aid to rapid field intensity assessments. Interfaces available on the field monitors include serial, bi-directional, optically and fibre-optic RS232, and IR remote control.
