Description

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.

Area Monitoring

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.

Field Monitoring

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.

System Operation

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.
