Product details
These loop powered indicators have third party Ex ec and Ex tc certification allowing them to be installed in a Ex e, Ex p or Ex t panel enclosure located in Zone 2 or 22, without the need for a barrier or galvanic isolator, and without invalidating the panel enclosures certification.  Both models have rugged Stainless Steel cases and large high contrast displays with a wide viewing angle and operating temperature range.

Both models can be supplied custom calibrated and labelled with scale and tag information for no additional charge.
