Introduction
The document introduces the new 'E' range of loop-powered 4/20mA indicators by BEKA associates Ltd, designed for use in both hazardous and safe areas. These indicators feature large, easy-to-read displays, robust enclosures, and a wide ambient temperature range.

Specifications
The indicators are available in field and panel mounting models, with options for hazardous area certifications. They feature a large, high-contrast display, less than 1.2V drop in the 4/20mA loop, and an ambient operating temperature range of -40ºC to +70ºC. Additional features include a square root extractor, 16-segment adjustable lineariser, tare function, and accurate calibration without an external current source. The printed circuit boards are coated for maximum reliability, and there is no charge for custom calibration, scale, and tagging. All models come with a three-year guarantee.

Field Mounting Indicators
These indicators are housed in robust IP66 GRP enclosures with separate terminal compartments. They are available with 4-digit or 5-digit displays, with options for hazardous area certification including intrinsic safety Ex i for gas and dust, and Ex nA & Ex tc for gas and dust. Optional features include an external keypad, backlight, custom etched stainless steel legend plate, and stainless steel pipe mounting kits.

Panel Mounting Indicators
Panel mounting indicators have a low profile and are available in 96 x 48mm or 144 x 72mm DIN enclosures. They feature 4-digit or 5-digit displays with optional backlight and dual alarms with isolated solid-state outputs. Models are available with intrinsic safety certification for gas and dust.

Models and Certifications
The document lists various models with their respective certifications for use in different zones, including intrinsically safe models for Zones 0, 1, 2, 20, 21, and 22, type n models for Zones 2 and 22, and general-purpose models for safe areas.

New Rate Totalisers
Complementary loop-powered 4/20mA totalisers are available with separate rate and total displays, including many standard features of the indicators. Models include intrinsically safe and uncertified general-purpose options.
