CoRoM Connecting Rod Bearing Sensor
Connecting Rod Temperature Sensor For Sulzer ZA40 Engines
CoRoM Sulzer ZA40
CoRoM Sulzer ZA40 is a batteryless telemetry system providing instant bearing metal temperature data for Sulzer ZA40 engines.
Mounted directly on the con-rod bearing cap, CoRoM is the world's first batteryless bearing monitoring sensor requiring zero battery replacement, cabling, or external power.
Generates electricity directly from the mechanical acceleration of the piston and con-rod. Zero battery explosion or thermal runaway risk in high-temperature crankcase environments.
Measures bearing metal temperature and splash oil temperature simultaneously, capturing micro-friction at the source long before Oil Mist Detectors (OMD) detect smoke.
Transmits data via BLE to the Wi-GaTe receiver gateway outside the crankcase, providing seamless data via Modbus RTU, Modbus TCP/IP, and Profinet to vessel AMS and SCADA.
Why Traditional Oil Mist Detectors Are Too Late
Oil Mist Detectors (OMD) and splash oil temperature systems used in marine engines are inherently reactive. They trigger alarms only after oil mist reaches critical levels in the crankcase. By the time smoke appears, the bearing has already melted, seized to the crankshaft, and micro-cracks have formed.
Unplanned Downtime & Severe Financial Impact
A bearing seizure leads to crankshaft re-grinding, complete crankshaft replacement, con-rod fracture, and engine block destruction. The resulting off-hire loss for shipowners and plant operators is immense.
Preventing Damage at the Source with CoRoM
CoRoM does not wait for smoke. It detects metal temperature rise at the very onset of metal-to-metal contact, protecting the crankshaft 100% and preventing major overhaul costs.
Non-Intrusive & Non-Destructive Easy Installation
CoRoM is easily installed without any drilling, tapping, welding, or mechanical modification to the connecting rod thanks to its design tailored to engine models. Engine OEM warranty and structural integrity remain 100% intact. Installation takes an average of 10-15 minutes per cylinder.
Dual Thermal Sensor Smart Diagnostics
Compares con-rod bearing metal temperature with splash oil temperature in milliseconds, distinguishing lubrication failure from mechanical wear to provide precise diagnostics.
Autonomously Monitor Your Fleet's Bearing Health
CoRoM sensors feed the most critical data into your engine's digital twin. Powered by kinetic energy harvesting, these sensors work in full synergy with the external Wi-GaTe receiver gateway.
