Compact field mounting indicators awarded North American certification
15 October 2018
BEKA associates have received US and Canadian intrinsic safety and nonincendive certification for the recently introduced compact BA304G and BA324G 4/20mA loop powered, field mounting indicators. These instruments, which already have IECEx and ATEX approval, feature a robust, IP66 impact resistant GRP enclosure with an 8mm thick armoured glass window, while retaining the easy to read very large displays of earlier models.
The 'G' indicators offer a choice of four 34mm high digits, or five 29mm high digits plus a 31 segment bargraph. All have a wide operating temperature of –40ºC to +70ºC and include a square root extractor, sixteen segment lineariser and internal calibrator. For no additional charge, instruments can be supplied calibrated to customer requirements with a novel slide-in scale card showing the units of measurement and tagging information.
Accessories include a backlight that may be loop or separately powered, dual alarms with isolated solid state outputs, stainless steel legend plates plus pipe and panel mounting kits.
Intrinsically safe models are available with ATEX, IECEx, ETL and cETL certification permitting installation in gas and dust hazardous areas. For applications in Zone 2 and 22 the BA304NG and the BA324NG have IECEx and ATEX Ex nA approval, recently supplemented by AEx nA certification for use in the USA and Ex nA certification for use in Canada. This permits installation without the need for Zener barriers or galvanic isolators which significantly reduces installation cost. General purpose non certified models are also available.
As with all BEKA products, these new indicators have a three year guarantee and for customers wishing to evaluate an indicator on-site, a free three month sale or return evaluation service is available.
