Mark of certification to ATEX Directive 94/9/EC Mark of certification to IECEx standard
Mark of FM approval for the U.S. and Canada
New fourth generation 'E' Series loop powered 4-20mA indicators include models for field and panel mounting in both safe and hazardous locations. The latest LCD technology enables full 4-digit readout with up to 34mm high numerals, or 5-digit readout with up to 29mm numerals plus a bargraph. High contrast and wide viewing angles provide good visibility under adverse lighting conditions, and a wide operating temperature range satisfies worldwide environmental needs.

Included and optional features provide internal calibration source, alarm outputs, display backlighting, linerarization, square root extraction, and tare calculation.

Intrinsically safe versions have FM approval for both the U.S. and Canada, plus ATEX for Europe, and IECEx for other international destinations. The FM approval includes use as non-incendive devices in Division 2 locations in current-limited loops without the need for a safety barrier. Similarly, Type nL models are ATEX and IECEx certified for use in Zone 2 locations.

All Beka indicators are calibrated to customer requirements free of charge and can be labeled to show units of measurement, tag number, and application.
Front panel pushbuttons enable operator display checks, also configuration and calibration. The latter functions can be passcode protected.
