Dr. E. Horn CLDM-System

Cylinder Liner Diameter Measurement (CLDM-System)

The CLDM system from Dr. E. Horn enables the crew to measure the liner wear of two-stroke engines without removing the cylinder head – directly through the scavenge ports. Equipped with high-precision eddy current sensors and bore-specific calibration, the crew can perform measurements quickly, reliably, and without external service providers. The recorded data is automatically analyzed by the supplied software, generating detailed reports in both 2D and 3D.

The CLDM have many advantages:

Amortises in less than 18 months
Operated by the crew without risk of mishandling
Calibration checks possible at any time

We deliver directly and globally to end-users, agents, and resellers.

Flexible - Precise - Economical

The CLDM liner wear measuring tool from Dr. E. Horn enables engine crews to accurately monitor cylinder liner wear on two-stroke engines - without removing the cylinder head. Measurements are taken quickly and safely through the scavenge ports, allowing crews to perform condition checks at any time during operation.

Built on HORN’s proven eddy-current sensor technology, the CLDM incorporates the same high-precision sensors trusted for years in the HORN bearing monitoring system. Each unit is individually calibrated to the specific engine bore, ensuring consistent, repeatable measurements under real-world conditions.

Designed for practical, onboard use, the CLDM offers a straightforward workflow for marine engineers. Measurement data is automatically processed in the dedicated software, which delivers clear analysis and generates a comprehensive liner wear report for maintenance planning and trend monitoring.

Key features

The CLDM system has many valuable features but the key features of the System are:

Cost saving
Liner wear can be measured at any harbour
Measurement can be done by the crew
Easy to operate without mishandling
Calibration checks by the operator at any time
Very robust (no optics, no moving parts, IP65)

The CLDM system consists of 5 components:

1. CLDM as described above
2. Operator device, communicating with the CLDM via infrared
3. Draw-wire encoder to record the position of the CLDM inside the liner
4. Calibration tool and case packaging
5. Evaluation software on USB-pendrive

All wear results are documented in accordance with the vendor’s maintenance manual and are
visualized additionally in 2D and 3D over the entire stroke.

From Failure Prevention to Performance Optimization

Yesterday’s challenges were about preventing failures - today, the focus is on higher standards. With smaller crews, preventive maintenance is more critical than ever, while predictive maintenance relies on standardized data exchange across automation layers.

Enhance this by integrating multiple measurement methods, ensuring higher data quality and faster response times. These monitoring systems use multiple microcontrollers to separate collected and transmitted data, strengthening cybersecurity.
