An extensive selection of loop-powered 4/20mA indicators, including models for field and panel mounting in safe and hazardous areas. Basic loop-powered instruments are easy and inexpensive to apply as they require no additional power supply and associated wiring.

Accessories including alarms, square root extractors, linearisers and display backlights further extend the application of these instruments. Most models can now be supplied with the new loop-powered display backlight which provides sufficient illumination for the display to be read in poor lighting conditions even when used with an intrinsic safety barrier.

All the intrinsically safe versions have ATEX and FM certification allowing installation in Europe and the USA. The Type nL models have ATEX certification permitting use in Zone 2 without intrinsic safety barriers or isolators.

All models are calibrated to customer requirements free of charge and they can be labeled to show units of measurement, tag number and application.
