Autonomous cathodic-protection potential monitoring alarm. The AP200 adds a remote relay output. 10-year battery life, standard (IP66) or flameproof (Ex II 2 G) versions.

Potential alarm AP100 and AP200 (ADF or Standard): overview

The AP100 and AP200 potential alarms are autonomous devices that allow personnel with no particular cathodic-protection knowledge to visually check that their system is working correctly. The AP200 features a volt-free relay contact to report a fault remotely.

To guarantee that a fault is observed, an acknowledgement without opening the enclosure is required to return to the normal state. Thanks to the embedded very-low-power and optical technologies, battery life reaches ten years in normal mode and at least one year in alarm mode.

This product is particularly recommended for monitoring buried tanks, service stations, hazardous areas and isolated sites with no power source. Two versions are available: standard (ABS housing, IP66) and flameproof ADF (marine aluminium alloy, Ex II 2 G – Eexd IIC T6) for gas zones 1 and 2.

Choosing in two questions

First question: should the fault be seen on site or reported? A regularly visited site only needs the AP100 and its indicator; an isolated site, or one monitored from a control room, calls for the AP200 and its reporting relay. Second question: is the site ATEX-classified? If so, the flameproof ADF version is required; otherwise, the standard version in an ABS housing is enough.

Why a self-powered alarm

Battery-powered, the alarm depends neither on the mains nor on the rectifier it monitors: it stays reliable precisely when the installation fails. The ten-year battery life in normal mode means it can be installed on sites without power and left alone between maintenance visits.
