Amot will feature the innovative XTS-W bearing wear conditioning system at the SMM Exhibition, offering the earliest warning of bearing wear and trends monitoring This system actually detects wear of main, big end and crosshead bearings on large diesel marine engines before steel-on-steel contact occurs, unlike traditional temperature monitoring and oil mist detection techniques that allow shutdown before failure but not before problems have already started

Air shut-off valve protects diesel engines
The control panel monitors engine speed and sends a shut-down demand to the valve if it exceeds a set limit.
Container ships stay safe with bearing monitors
Systems monitor the crank train bearings of large two-stroke diesel engines in real time, providing an early warning of bearing wear and avoiding catastrophic failures.
The Amot XTS-W system uses a totally new concept based on linear bearing wear instrumentation.
It is the most cost-effective solution to provide operators the maximum time for controlled engine shutdown and ship manoeuvres and allowing the most effective planned maintenance.
Proven displacement sensing technology ensures high sensing accuracy and linear response, progressive wear indication and robust sensor design.
Other features include advanced internal signal linearisation, built-in temperature compensation and industry standard passive 4-20mA output.
The sensors produce a signal with every engine revolution, passed to a signal processing unit generating a continuous representation of the extent of bearing wear.
This is postprocessed in a final stage to generate alarm/warning signals and provide wear trend monitoring functionality.
The output can be integrated into the main engine control system if desired.
The system's advanced signal processing offers multi-channel operation, standard interfacing and easy, automated calibration.
Based around a RISC microprocessor, it can simultaneously process signals from up to 12 displacement sensors and permits automatic sensor signal sequencing for the fastest possible response time.
Full PC access to all processing parameters is via an RS232 port and no special software is required.
A flexible postprocessor is based around the Amot 8635A, which is a fully programmable and flexible controller with extensive analogue and logic processing capability.
Continuous bearing monitoring enables real-time wear trend analysis, with a picture of the rate of change of bearing wear giving a much earlier indication of a potential engine problem than a simple alarm threshold can provide. Request a free brochure from AMOT ...
