- Large non multiplexed displays, models with:
4 digits: 15mm high
5 digits: 11mm high + bargraph - Rugged stainless steel cases for use in Ex n, Ex e,
Ex p and Ex t panel enclosures in Zones 2 & 22 - Internal calibrator
- Root extractor and lineariser
- Tare function
- Optional:
Backlight – may be loop or separately powered
Alarms
These loop powered indicators have third party Ex nA and Ex tc certification allowing them to be installed in a Ex n, Ex e, Ex p or Ex t panel enclosure located in Zone 2 or 22 without the need for a barrier or galvanic isolator. They have rugged stainless steel cases and large high contrast displays with a wide viewing angle and can operate over a wide temperature range.
Both models can be supplied custom calibrated and labelled with scale and tag information for no additional charge.
