Independent Type Tank High/Overfill Alarm System(Magnetic Float Type)
HANLA’s cargo tank high/overfill alarm system is thoroughly designed according to USCG latest requirements, and are to be required by IBC code.
General Information
This alarm system consists of level alarm sensor, I.S barrier and alarm panel. When the liquid level reaches a set point, the reed switch in the alarm sensor is actuated by magnetic float.
This signal is connected to alarm annunciator through safety barrier. At the same time, we can get audible and visible alarm on the main alarm panel as well as external alarm on the bridge top. The 95% of volume is normally for high alarm and 98% of volume is normally for overfill alarm.
Most advanced electric technology for high reliability and durability.
Certified by major certifying authorities.
Designed for all kind of liquid.
Simple for construction.
Intrinsically safe designed unit is applicable to all kind of inflammable fluids.
Lifting type manual test device which can check the function.
These systems are used for the level alarm in cargo tanks of all kind of oil and chemical carriers.
