Measuring Electric And Magnetic Fields Simultaneously: NIM-511 And NIM-513
Industrial users of RF energy have specific needs that are unlike those of typical communications users. Common frequencies employed by Plasma generation systems and Vinyl Welders tend to be standardized as are the materials that are used. For those companies using high power 13.56 and 27.12 MHz systems, Narda-STS has developed the new NIM series, the NIM-511 and NIM-513. The NIM-513 covers 10 to 42 MHz, and is perfect for users of 27.12 MHz systems, while the NIM-511 covers a broader 300 kHz to 100 MHz frequency range for semiconductor applications that use not only 13.56 MHz, but might also have nearby Induction Heating coils operating in the 100-400 kHz region.
The Narda Models NIM-511 and NIM-513 combine an unprecedented ease of operation with powerful measurement capabilities. It provides the industrial plant manager and safety professional with an accurate and inexpensive solution for proving compliance with regulations that cover exposure to RF radiation. Both models provide a complete measurement system comprised of an extremely easy to operate meter and a probe that contains sensors to measure both the electric (E) and magnetic (H) field components of an electromagnetic wave.
The NIM-511 and the NIM-513 were designed to make measurements a simple process that does not allow the most common mistakes to happen.
Major safety standards worldwide require that both the electric and the magnetic field components (E and H fields) be measured for equipment operating below 300 MHz. Most high power industrial equipment operates at one of the frequencies allocated for Industrial, Scientific, and Medical (ISM) applications. Two ISM frequencies - 27.12 MHz and 13.56 MHz – are used extensively. The majority of heat sealers and induction heaters operate at 27.12 MHz while most semiconductor processing equipment operates at 13.56 MHz. The NIM-513 operates from 10 MHz to 42 MHz and is adjusted to the reference calibration frequency at 27.12 MHz. The NIM-511 has a much broader sensor that operates from 300 kHz to 100 MHz and is adjusted to the reference calibration frequency at 13.56 MHz.
