Meet PiTeM Now
Monitor piston cooling without disassembly, and prevent damage before it happens.
PiTeM
PiTeM is the world's first autonomous sensor system that wirelessly monitors piston temperature without cables. Detect piston head overheating and bearing issues before damage occurs.
Installed without removing any engine parts, it measures oil temperature exiting the piston for real‑time efficiency analysis.
Runs completely autonomously by converting engine heat into electricity—no external power or batteries required.
Detects critical faults like piston head overheating, bearing wear, and ring seizure before any damage occurs.
Transmits data via BLE, offering flexible connectivity to existing plant infrastructure.
INVISIBLE THREAT
Overheating at the piston tip is a silent killer. Traditional methods only notice it after catastrophic failure during engine teardown.
Why Cooling Efficiency Matters
The piston is cooled by a micron‑thin oil film that directly impacts engine power output. No external sensor can measure this film’s effectiveness without tracking oil flow in and out.
See Through with ΔT
PiTeM measures inlet oil temperature (PiTeM‑in) and outlet temperature (PiTeM‑out). Their difference (ΔT) gives a real‑time view of piston cooling efficiency.
PiTeM‑in & PiTeM‑out: Two Points, One Truth
PiTeM‑in watches oil entering the biellette, while PiTeM‑out tracks oil leaving the piston head. This dual measurement flags overheating, bearing wear, ring seizure, and excessive combustion temperatures early.
No Disassembly, No Wiring, No Battery Changes
The system harvests energy via a Thermoelectric Generator (TEG) from engine heat. Data is wirelessly sent from the moving piston to a gateway—installation requires no piston removal, delivering zero‑maintenance operation.
From Scheduled to Data‑Driven Maintenance
Track ΔT trends to schedule maintenance based on actual engine condition. Intervene before heat buildup causes damage. PiTeM turns predictive maintenance into reality.
No guesswork, no accidental disassembly. Stay ahead of motor management—see piston cooling efficiency in real time and resolve issues while they’re still small.

Frequently Asked Questions
No. The biggest innovation of PiTeM is that it can be installed without taking any engine parts apart, minimizing downtime while providing autonomous monitoring.
PiTeM detects piston head overheating, biellette bearing issues, ring seizure, and excessive combustion temperatures in real time before damage occurs.
PiTeM technology has been successfully tested on MAN 32/40 engines and is compatible with all similarly sized large internal‑combustion engines.
PiTeM is completely battery‑less. It harvests energy from the engine’s operating heat via a thermoelectric generator.
Data from the moving piston is wirelessly transmitted via BLE to a gateway system and then to the dashboard.
The temperature of the discharged oil directly reflects piston cooling efficiency. Abnormalities indicate early warnings of overheating or lubrication issues.
PiTeM makes the previously invisible piston interior visible, turning scheduled maintenance into condition‑based maintenance, preventing unnecessary disassembly and extending engine life.
