LAG 14 ER

LAG 14 ER is a class II (EN 13160-1:2003) leak detector system with an intrinsically safe probe circuit for the monitoring of double-skin tanks through a conductive fluid in the interstitial space. This system is  composed of a control unit, a container for the monitoring fluid and a probe. LAG 14 ER can be installed on tanks which contain flammable liquids, non-flammable liquids and even explosives - class A I, A II, A III  and B (Ref. VbF. Flammable liquids regulation). The control unit is connected through tubing inserted in the interstitial space of the tank and constantly monitors the integrity of both internal and external walls of the  tank. The control liquid used to fill the interstitial space and the control unit container is an aqueous solution made with 30% of high-purity propylene glycol, a colorless, nearly odorless, clear, viscous liquid.

OPERATING PRINCIPLE:
The system exploits the conductive properties of the detector fluid in which two electrodes are immersed and which can also activate the alarm circuit without any mechanical movement. The control unit  constantly monitors the potential between the electrodes immersed in the liquid. In case leak occurs in the interstitial space, the liquid level in the tank decreases, changing the potential of the electrodes and,  consequently, activating the alarms, both acoustic and optical. Alarms can be of local type, integrated in the system, and, where installed, remote via relay. The tank container LAG, made of antistatic plastic  material, can be installed in potentially explosive zones. The electronic control unit is not of explosion proof type so cannot be installed in zones classified EX. A single control unit is able to monitor several tanks
