UWKS Type Cargo Water Ingress Alarm Device
Product Description
UWKS Type Cargo Water Ingress Alarm Device
Product Introduction:
This device is designed according to SOLAS Ⅻ-12, water lever monitor and alarm of bulk carrier cargo hold, ballast tank and close dry space. The characters of this system are easily operation, convenient for maintain and running safe stability. When the water ingress bulk carrier cargo hold, ballast tank and close dry space etc and reaching the limited water level, the system will give alarm.
Function Of Device:
The device consists of main alarm control panel in ECR, extended alarm panel on the bridge, safety barrier and water ingress detection sensor located on each gauge point etc. The detector is to be fitted in the aft part of each cargo hold, as close to the center line as practicable, and arranged to provide visual & audible pre-alarm signal when the water depth in the cargo hold reaches 0.5m; the device provides visual & audible main alarm signal when the water depth in the cargo hold reaches 2m but not more than 15% of hold depth; the device provides audible & visual alarm signal when the water level in dry space or void space reaches 0.1m above bottom space; the device provides audible & visual alarm signal when the water level in ballasts water tank, collision bulkhead reaches 10% of the volume of the tank.
Operating Principle:
The pre & main water ingress detection sensors are used for detecting the water level of cargo hold, when the water in the tank to be measured reaches the set alarm point, water ingress detection sensor outputs water level alarm signal to main alarm panel of the system through safety barrier, and provides audible & visual alarms. At the same time, the audible & visual alarms are activated on the main alarm panel installed on the bridge. The system has the functions of accept horn, accept flash, dimming, overriding, test function, main power fail alarm, sensor fail alarm etc. The device can support multipoint detection alarm.
Features:
*Intrinsically safe design can be applicable to dangerous area
*Available for any number of detecting points
*Convenient and flexible monitoring configuration
*Complete function, steady and reliable
