NBM-580 Broadband Field Meter

Monitor and Alarm System for Electromagnetic Fields.

The NBM-580 collects the measurement values from up to eight spatially distributed measurement stations, records them continuously, and triggers alarms if limit values are exceeded.
Nardalert S3 monitors can be used for as measuring stations monitoring limit values on e.g. transmitter equipment or in industrial environments. The Narda Broadband Field Meter NBM-520 with its measuring probes is suitable for more precise monitoring.
The NBM-580 manages all the data centrally. It can be shown directly on the screen, output via IEEE-488 or remotely downloaded by Ethernet. Up to eight Nardalert S3 or NBM-520 (or a combination of both) can be connected at distances of several tens to hundreds of meters. Four optical and four USB inputs are provided for this purpose. Low and high current alarm relays are also built in.

The NBM-580 makes precision measurements for human safety purposes, particularly in workplace environments where high electric or magnetic field strengths are likely. It can also be used to demonstrate the electromagnetic compatibility (EMC) of devices and equipment.
  • Measuring field strengths as part of general safety regulations
  • Measuring the field strengths around transmitting and radar equipment to establish safety zones and for monitoring during operations
  • Measuring the field strength emanating from mobile phone repeaters and satellite communications systems to ensure compliance with human safety limit values
  • Measuring the field strength in the industrial workplace environment, such as plastics welding equipment, RF heating, tempering, and drying equipment 
  • Measurements to ensure the safety of persons using diathermy equipment and other medical equipment that  generates high frequency radiation
  • Field strength measurements in TEM cells and absorber chambers
