AP200 ATEX potential alarm with remote output

AP200 ATEX potential alarm with remote output: overview

The flameproof AP200 potential alarm is an autonomous device that allows personnel with no particular cathodic-protection knowledge to check that their system is working correctly, visually or remotely. An acknowledgement without opening the enclosure returns it to the normal state. It is recommended for monitoring buried tanks, service stations, hazardous areas and isolated sites without power.

It incorporates very-low-power and optical technologies, with a simplified human-machine interface and setting, and a battery life of ten years in normal mode (one year in alarm mode). Its marine aluminium alloy enclosure (AS10GY30) is marked Ex II 2 G – Eexd IIC T6, IP56, usable in an ATEX zone 2 environment. Powered by a 3.6 V 16.4 Ah lithium battery (D case), consumption 70 µA in normal mode.

The problem it solves

On an oil depot or a filling station, checking cathodic protection means entering the hazardous area, with a work permit and precautions. As a result, checks become infrequent and a fault can go unnoticed for a long time. The AP200 ATEX monitors continuously from inside the zone and reports faults remotely: checking no longer requires a site visit.

When to choose it

Whenever you need both a flameproof enclosure and remote fault reporting. If the site is not ATEX-classified, the standard version is enough; if remote reporting is not needed, the AP100 covers the requirement.
