New loop powered Rate Totalisers have a large display

Posted: Thursday 9th August 2012

BEKA associates new field and panel mounting loop-powered 4/20mA Rate Totalisers have large easy to read displays which can simultaneously show rate and total flow in engineering units. All models include a root extractor, lineariser and calibrator with optional dual alarms and a backlight that can be loop or separately powered.

Field mounting models have a robust IP66 GRP enclosure with an armoured glass window and a separate terminal compartment making them suitable for installation in harsh industrial environments. Panel mounting models have a 144 x 72 DIN enclosure with an IP66 front panel.

In addition to general purpose models, versions are available with ATEX, IECEx, and FM intrinsic safety certification permitting installation in gas and dust hazardous areas. For lower risk Zone 2 or 22 applications, field mounting models with Ex nA and Ex tc approval permit installation without the need for Zener barriers or galvanic isolators significantly reducing installation cost.
