Westek Electronics released an electromagnetic field analyser capable of measurements from 15 Hz to 30 MHz.
The Taoma universal electromagnetic field analyser incorporates the Microsoft Windows CE.NET operating system, enabling users to analyse data in the field without having to connect to a separate computer.
The Taoma electromagnetic field analyser is available with temperature and humidity sensors, as well as a GPS module providing exact physical location of the measurements. Also provided with the instrument is an optional GPRS module permitting remote data transmission.
Other standard interfaces included in the Westek Electronics Taoma field analyser include RS232 (electrical or optical), USB, Ethernet (RJ-45), and an SD card slot, as well as a 0-5 volt scanning input.
The Taoma analyser has a data memory of 512 MB, thus allowing the on-board storage of up to 250 hours of measurement results. Results can be displayed as instantaneous, average, or maximum values or as amplitude-time variations.
The Taoma electromagnetic field analyser comes standard with a VGA 6.4 inch TFT display, an alphanumerical keyboard with specific function access keys, and an integrated navigational trackball.
The probes supplied with the instrument include magnetic induction (B) from 15 Hz to 100 kHz; electric field (E) in the range of 15 Hz to 100 kHz; E fields in the range of 100 kHz to 6 GHz; E fields in the range of 3 MHz to 18 GHz; and magnetic strength (H) fields in the range 300 kHz to 30 MHz.
The Westek Electronics Taoma field analyser is suitable for a range of applications that include the investigation of medium-voltage power fields on the growth of soy seedlings and the study of non-thermal effects on human subjects as a result of exposure to power-line fields.
Numerical techniques and their associated computer programs for the calculation of field characteristics can be a useful aid for designers of transmission lines and towers, as well as for environmental protection authorities. Theoretical calculations can then be contrasted against practical measurements in HV substations.
