Narda Introduces H-Field Probes for Isotropic Measurement and Analysis
Narda Safety Test Solutions' engineers have achieved a breakthrough in isotropic measurement and analysis of low-frequency magnetic fields in the form of their latest digital H-field probe, the BFD-400-1. When connected to the FieldMan, Narda’s smart, intuitive broadband EMF meter, it reliably and safely captures and evaluates the exposure of operatives to magnetic fields at frequencies between 1 Hz and 400 kHz, which are present in the automotive and railroad industries and many other industrial applications.
Together with the compact EHP-50F Probe, the frequency-selective FFT field analyzer for isotropic measurement of electric and magnetic fields, which can now also be used with the FieldMan, they both cover the entire low-frequency range for workplace safety applications. The probes automatically evaluate the exposure levels in accordance with the major standards such as EU Directive 2013/35/EU, ICNIRP or IEEE, while the FieldMan indicated the exposure level index directly as a percentage of the limit value for the selected standard.
BFD-400-1 applications
This new development from the Pfullingen-based test equipment specialist is aimed squarely at all stakeholders, public authorities, institutes, service providers and authorized agents in the field of workplace safety who are concerned with standard-compliant monitoring of the current international standards covering safety in low-frequency magnetic fields, such as EU Directive 2013/35/EU, ICNIRP, IEEE or CENELEC. The typical measurement environments include: industrial production areas such as induction heating and smelting; electric welding equipment; the railroad industry; electrical medical equipment; energy supply systems; and the automotive sector. In particular, e-mobility has opened up a whole new field of applications that, as well as EMC measurements, includes investigating the localized field exposure of persons seated in electric vehicles using several specially positioned measuring probes.
Technical achievements
The newly developed BFD-400-1 takes care of calculating the measured values within the probe in addition to capturing the measurements in the same way as all the digital probes for the FieldMan. The active components required for processing the measured values are actually contained in the connector of the probe itself. The digital probe from Narda STS can therefore be used without the basic unit. This unique feature has several key advantages.
