Valcom OMDS Atmospheric Oil Mist Detection System


The Valcom OMDS is an Atmospheric Oil Mist Detection System for use in marine and offshore applications. It is developed for installation in machinery rooms and pump rooms in commercial, naval, ro-ro ships. OMD oil mist measuring is based on the principle of optical scattering.

Infrared light emitted from a LED is received from two photodiodes for measure and reference purpose; by the comparison between the photodiodes output, the presence of oil mist can be detected. OMD is based on a digital electronics for signal analysis, including fault detection and photodiodes degrading monitoring system.

Two external bicolored LEDs show the instrument functioning state and the alarm state activation. The external case of the detector is made of AISI316 St.St. and anodized aluminium alloy and the installation is performed with a mounting bracket.

The VALCOM® DIGITAL HART® acquisition system enables several OMD to be connected on the same pair of wires in a multidrop network configuration. Communications in multidrop mode are entirely digital. Standard HART® commands are used to communicate with field instruments to determine process variables or device parameter and diagnostic information. It is also possible to make instruments setup and calibration remotely. The built-in ethernet network card allows the join of an existent network or the creation of a new point to point network to send data or working from a remote position.
