SiCOMS® performs compartment specific oil mist monitoring and lubrication oil temperature measurements.
The measuring unit of SiCOMS® for a compartment consists of a finger-shaped optical sensor with system redundancy, and a multiple chamber Splash Oil Guard (SOG) which prevents the sensor from being soiled with splash oil, but allows the oil mist and water vapour to enter the sensor light beam within milliseconds. So, the reaction time of each sensor and the whole system is less than one second.
The SOG is mounted from the inner side of the engine wall into already existing drilling of the crankcase. The sensor is pushed into the installed SOG. So, the SiCOMS® sensor installation is very simple. This also means that the optical measuring section is positioned inside the crankcase area where oil mist could occur. No piping is needed!
The SiCOMS® sensors are interconnected via two redundant serial bus interfaces. If necessary, a sensor can be easily dismounted, for example for cleaning, while the engine is running without affecting the system’s functionality.
SiCOMS® does not have any movable mechanical parts and hence does not undergo any wear and tear.
Example for an Installation of SOG and sensor
The sensor and alarm system’s reaction time is in the range of less than one second.
The SOG and the sensors are specific for each engine. Due to differences in each engine design which result in different wall thicknesses different SOG and sensor lengths are required. The needed length will be determined by personell of motcom GmbH or an authorized partner.
If the SOG and the sensor are installed near or in a section with a high splash oil concentration the usage of the Diffusor add-on is required (also refer to Chapter 5.2 Installation Position).
