Narda NBM-580 Broadband Radiation Meter

The Narda NBM-580 allows users to combine multiple-sensor installations into a fully functioning monitoring or alarm system. Configured as a single communication point, this product allows complete control over sensors that are stationed tens or hundreds of meters away from the metering station. The built-in color, touch screen display can be user configured to display individual readings of each sensor or the maximum, minimum or average of one or more of the connected sensors. Programmable analog voltage outputs can also be arranged to generate positive or negative going voltages, depending on detected fields. Digital TTL-levels can be tied to alarm settings as well as two built-in high power relays. 

Intelligent area monitoring is made possible by the NBM-580 and Nardalert S3 (NS3) monitors. NS3 monitors can be placed strategically around highpower test areas, powered by DC voltage and connected by fiber optic cables back to the NBM-580. Levels detected by the monitors can be continuously compared to preset thresholds and generate immediate alarms if those thresholds are exceeded. With the built-in Ethernet connection, monitoring can be configured anywhere that a connection exists. NS3 monitors have NEMA enclosure and solar charging panel optional accessories for outdoor monitoring applications.

For more precise field monitoring, the NBM-580 can be connected to NBM meters and probes. A typical system would consist of NBM series field probes and NBM-520 meters. The fiber optic output of the NBM-520 is routed to the NBM-580 where display of the detected fields is processed. Many NBM probes cover dynamic ranges of 60 dB and provide detection of E or H fields to provide coverage of most any industrial, communication or military applications.

As the NBM-580 is a metering station it requires no recalibration. Therefore it can form part of a comprehensive monitoring system where it can be semi-permanently mounted. All probes, meters and Nardalerts do require periodic re-calibration and can be readily substituted with other calibrated units directly for seamless operation.
