T40MAR – Marine‑certified Torque Transducer for Maximum Engine Efficiency

T40MAR is a high‑precision, marine‑certified torque transducer engineered to deliver accurate, reliable load‑signal measurement for ship engines. By enabling better control of torque and speed across the drivetrain, the T40MAR helps marine operators significantly reduce fuel consumption, improve engine performance, and comply with key international directives such as MARPOL.

Key features

Direct torque measurement up to 400 kN·m
No bearings and slip rings
Non‑contact, digital signal transmission – no wear, no maintenance
Fast, low‑latency signal processing for advanced control systems
Parameter retention even after power loss
Expandable I/O options: analog and digital outputs
Easy installation and compatibility with MP60 marine measurement electronics

Built for harsh marine conditions

Designed for demanding marine environments, the T40MAR is officially certified for shipboard use by leading classification bodies including:

Germanischer Lloyd (GL)
Det Norske Veritas^® (DNV^®/DNV GL^®)
American Bureau of Shipping (ABS)
Bureau Veritas (BV)
Korean Register (KR)
China Classification Society (CCS)
Registro Italiano Navale (RINA)

The result is accurate torque and speed measurement that enables highly precise load‑signal determination – the essential input for modern engine control systems. By improving control systems and engine efficiency, the T40MAR supports compliance with international marine environmental directives, including MARPOL.

Typical applications

From commercial fleets to naval applications, the T40MAR delivers rugged, failsafe performance in high‑vibration engine rooms and large‑drive environments. It forms the backbone of reliable, efficient engine management systems on modern vessels.

Fast and accurate torque measurement for reducing emissions is extremely important for the optimum running of gas and dual-fuel marine engines.

Exceptional measurement accuracy

With an HBK accuracy class of 0.15, the T40MAR ensures high fidelity in real‑time control and regulation systems, supported by extremely low signal delay. The extremely rigid and vibration‑resistant sensor design and non‑contact digital signal transmission ensures a 100% maintenance‑free system with a long service life, even under continuous heavy‑duty operation.

Flexible, reliable performance

The T40MAR torque transducer’s smart design features simplify integration and long‑term operation. Its parameters are securely retained even after a power loss, ensuring consistent performance without the need for reconfiguration. Connected to HBK’s TIM-EC interface module, the entire system offers expandable input/output options, including both analog and digital outputs – providing adaptability for a wide range of marine control and monitoring setups.

Installation is straightforward, with full compatibility alongside MP60 marine measurement electronics for seamless system integration. For specialized applications, the T40MAR is also available in customer‑specific designs, ensuring an optimal fit for unique vessel requirements.
