Rugged panel mounting indicators may be safely installed in Ex e cabinets

Thanks to a new range of BEKA intrinsically safe and Type n rugged panel mounting indicators, it is now possible to safely install 4/20mA loop powered indicators in Ex e increased safety and Ex p pressurised cabinets located in Zones 1 or 2 and in Ex n cabinets located in Zone 2 without invalidating the cabinet’s certification.

Housed in a 316 stainless steel case with an impact resistant IP66 front, these IECEx and ATEX (Read More) 

certified indicators significantly reduce installation complexity and cost. The instrument certificates define in which certified cabinets and in which Zones the indicators may be installed.

The Ex nA non-sparking certified indicators do not require a Zener barrier or galvanic isolator and may be installed in Zone 2 cabinets. For Zone 1 applications the intrinsically safe models should be used. Both are supported by Application Guides, AG310 for Ex nA and AG300 for Ex i applications.

These new rugged indicators include models with four 15mm high digits and five 11mm high digits plus a 31 segment bargraph. All have an operating temperature between –40oC and +70oC and include a square root extractor, sixteen segment lineariser and a tare function. Optional accessories include a backlight and dual alarm outputs.
