Description

VAF INSTRUMENTS TT-SENSE,83774

Product Overview The VAF INSTRUMENTS TT-SENSE part number 83774 is a marine optical shaft torque and thrust measuring system engineered for vessel propulsion performance monitoring, built to comply with DNV marine certification and IMO SEEMP requirements. Built for propeller thrust measurement, shaft torque monitoring, propulsion efficiency analysis, this robust shaft-mounted sensor withstands marine vibration, salt mist and wide temperature fluctuation, delivers stable 24/7 continuous operation, and serves as core propulsion measuring hardware for cargo ships, tankers, offshore vessels and merchant marine vessels.

Featuring non-contact optical sensing technology, integrated rotor and stator assembly, RS485 Modbus communication interface & real-time shaft speed calculation function. It mounts directly around the vessel propeller shaft, adapting to different shaft diameters on marine propulsion systems. The modular assembly allows separate replacement of optical sensing components without full propulsion system shutdown, greatly reducing vessel downtime for service. Equipped with maintenance-free optical pickup, high repeatability measurement & embedded self-diagnostic routine, mature hardware structure prevents signal interference and guarantees dependable shaft measurement performance during continuous duty.

For dependable propeller thrust measurement, shaft torque monitoring, propulsion efficiency analysis, TT-SENSE 83774 captures real-time thrust and torque data from the propeller shaft, calculates shaft power and supports hull resistance and propeller cavitation analysis for vessel fuel optimization. Reliable propeller thrust measurement, shaft torque monitoring, propulsion efficiency analysis, premium marine-grade optical and electronic components provide excellent long-term operational stability, extending service life in harsh marine shaft room working environments. Practical maintenance-free optical pickup, high repeatability measurement & embedded self-diagnostic routine, marine technicians can inspect measurement status and export propulsion data via PEM4 monitoring unit during routine vessel inspection.

During continuous propeller thrust measurement, shaft torque monitoring, propulsion efficiency analysis, this shaft measuring system is fully compatible with VAF PEM4 propulsion efficiency monitor, onboard DCS and vessel performance data platforms. Stable propeller thrust measurement, shaft torque monitoring, propulsion efficiency analysis, mature VAF TT-Sense marine shaft measurement technology with easy spare parts replacement and convenient after-sales maintenance. Robust maintenance-free optical pickup, high repeatability measurement & embedded self-diagnostic routine, simplifies shaft installation layout and reduces installation workload for vessel propulsion retrofitting and marine performance monitoring overhaul projects.
