Oil Mist Monitor DOMM

Since 1976, Daihatsu Diesel Mfg. Co., Ltd. has put OIL MIST DETECTOR continuously on the market. In 2004, model MD-SX which is of sensor type mounted on crankcasewas developed. It can directly measure the oil mist density inside crankcase in a waythe sensor is so mounted that the sensing part is sticking into the crankcase.
Conventional system has to take out oil mist for measurement from crankcase insidethrough piping.
The new system provides following merits by the oil mist level is sent out for thecontroller as digital signal.

Oil Mist Monitor DOMM

In recent years, as fire prevention measures for tankers, earlier detection on abnormaloil mist level in engine room is required as it is thought to be effective in pin-point the cause and its measures. Daihatsu Diesel Mfg. Co., Ltd. has further advanced MD-SX typedetector into OIL MIST MONITORING DEVICE, OMM type, whose development is based on thetechnologies of MD-SX type many classes give TYPE APPROVAL.
The new OMM type can provide visual display on oil mist level where it is likely togenerate.
The OMM type is expected to go into the market October, '07.

The system does not guarantee previention of disaster, such as a fire.
