Product Overview
The KYMA KDU-110 is a marine-grade performance monitoring display unit engineered to visualise real-time shaft power, torque, rotational speed and propulsion efficiency data collected from KYMA shaft power measurement systems. This panel-mounted display solves the critical challenge of localised machinery performance readout onboard vessels, enabling bridge and engine room operators to track propulsion load continuously without relying solely on remote SCADA terminals. Maintenance teams, shipowners and marine automation integrators benefit from the unit’s robust marine construction, stable data acquisition and straightforward integration with KYMA measurement transducers. This automation hardware delivers consistent, verified operational data to support fuel optimisation, machinery condition monitoring and regulatory reporting for commercial marine assets.
Key Functions
- Real-Time Propulsion Parameter Visualisation: The unit continuously receives measurement data and displays shaft power, torque and RPM values on its onboard screen. Operators can instantly identify load deviations during manoeuvring or cruising to avoid overloading main propulsion engines.
- Local Alarm & Threshold Monitoring: Configurable parameter thresholds trigger visual alerts when propulsion operating values exceed predefined safe limits. This provides immediate on-site notification before abnormal conditions escalate into mechanical wear or component failure.
- Serial Data Output for System Integration: The built-in RS232 port streams live measurement data to external converters, PLCs or vessel automation systems. This capability bridges standalone shaft power sensing equipment into wider shipboard monitoring networks.
- Marine Environment Stabilised Signal Processing: Optimised filtering suppresses vibration-induced signal noise common in engine rooms. Stable readings are maintained despite continuous machinery vibration and fluctuating ambient marine conditions.
Application Scenarios
- Commercial Cargo Vessel Engine Room Monitoring: Installed within main engine control consoles, the KYMA KDU-110 provides engineers direct visibility of propeller shaft load. Operators adjust engine output to minimise excessive torque spikes, extending shaftline bearing and gearbox service life while cutting fuel consumption.
- Offshore Support Vessel Propulsion Optimisation: For dynamically positioned offshore vessels, the display tracks varying shaft power under variable sea states. Crew reference live data to balance thrust demands, reduce unnecessary fuel burn and support vessel operational efficiency reporting for charter requirements.
- Retrofit Marine Automation Upgrades: Ideal for refit projects on older vessels lacking integrated propulsion monitoring. This display unit pairs with existing KYMA shaft power sensors, offering a cost-effective upgrade path without full replacement of primary measurement hardware.
