BEKA Loop Powered Digital Indicators for Process Control

Provide Process Information from 4-20mA signals in Hazardous Areas & Extreme Environments

  • Large, non-multiplexed digital displays
  • Numerals up to 34mm high
  • Full 4 & 5 digit readout, plus bargraph on selected models*
  • High contrast and wide angle viewing
  • Less than 1.2V drop in 4-20mA loop
  • -40°F to +158°F / -40°C to +70°C operating temperature
  • FM approvals, ATEX and IECEx certifications, for hazloc applications
  • Field & panel mounting models
  • Ingress protection up to IP66
  • Optional backlighting and alarm outputs
  • Square root extraction, tare, and linearization
  • Internal calibration source

* Vertical bargraph models BA326C & BA526C have 4-½ digit readout

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 nA 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.
