The OMD-12 Bilge Alarm Unit has been designed specifically for use in
conjunction with oil coolers or cooling water. At the further devolopment of the
OMD series special care has been taken for the higher water temperature. Also
the range has been modified according to the expected oil concentrations.
The instrument is built according the IMO Resolution MEPC. 60(33).
The unit is supplied with 2 works-adjusted alarms at 10 ppm. Other set points
(15 ppm or 20 ppm) are possible and can be adjusted on site at any time by
using the buttons at the front panel. If an alarm set point is exceed, the alarms
are visible at the front panel and the appropriate relays are switched.
Furthermore a 0(4) - 20 mA (equal to 0 - 30 ppm) signal output is available for
driving a recorder or external meter. The connection is done with an optional
available adapter.
