IMO Approved Bilge Water Alarm

Product Introduction:

The OCM-15A type bilge water alarm device has been designed specifically for use in continuous monitoring of oil-in-bilge water, 15 ppm alarm and control of discharge, detection, memory, printand enquiry of alarm status. It is applicable to detect boiler condensate water. And it applies to oil and chemical industries as well.

The OCM-15A type bilge water alarm device use the technology of near infrared measurement, which can display the detected result in real time. The unit is supplied with 2 works-adjusted alarms. The set point (15ppm factory set) could be adjusted at any moment through the panel. If an alarm set point is exceed, the alarms are visible at the front panel and the appropriate relays are switched, that can be achieved the movement control of overrun closedown or the treatment of overrun recycle, and the memory and enquiry of alarm record. Furthermore, a 4 - 20mA (equal to 0 – 15ppm) effective signal output is available for driving a recorder or external meter.

The certificate of type approval test has been obtained through comprehensive tests. This device is in accordance with the IMO-Resolution MEPC.107 (49).

Structure Specification:

OCM-15A type 15ppm Bilge Alarm box were used aluminum alloy chassis and ABS reinforced plastic plate stamping molding international standard chassis can withstand the impact strength and the strength test standards. Compact, strong, fully applicable to a variety of harsh environments long-term work. Cable entry selected in line with watertight cable entry, when you install the unused connection port with steel bars blocking blocked.

All the components are assembled in a cast aluminum alloy case and a cold-roll steel sheet case. The protection grade is IP45. The measure modules are directly installed in the printed circuit board. The compact structure and plug-in type technique make sure the replacement of modules easier, and the design of electric circuit more creative.

Measuring Principle:

Several optical sensors measures a combination of light scattered and absorbed by oil droplets in the sample stream. The sensor signals are then processed by a microprocessor to produce linearised output. If an alarm occurs, the two oil alarm relays are activated after the adjusted time delay. And it stores up the actual time, display value, alarm output status and alarm control feedback status. By front face menu operation, the memorized information can be enquired anytime. The microprocessor continuously monitors the condition of the sensor components and associated electronics to ensure that calibration accuracy is maintained over time and extremes of environmental conditions.
