The Woodward UMT1 Measuring Transducer (Part No. 8444-1019, Rev. F) is a precision signal-conditioning device designed to measure and convert AC voltage and current inputs into standardised output signals for use within marine control and power management systems. Operating across a measured AC voltage range of 57/100 (120)V with a maximum UL rating of 150V AC, and accepting a generator current input of 5A AC, the UMT1 plays a critical role in accurate power monitoring and load management aboard vessels. Powered by a 24V DC auxiliary supply and rated for ambient operating temperatures from -20 to 70 °C, this transducer is well-suited to the demanding thermal and electrical environments found in marine engine rooms and switchboard panels.
Key Features
✓ Measures AC voltage (IEC rated 57/100 (120)V AC, max 150V AC per UL) and generator current input of 5A AC, providing reliable signal conversion for power management applications.
✓ Operates on a 24V DC auxiliary supply with a maximum auxiliary current draw of 0.5A DC; compatible with both 50Hz and 60Hz electrical systems for global vessel operation.
✓ Wide operating temperature range of -20 to 70 °C ensures stable performance in engine rooms, switchboard enclosures, and other thermally variable onboard locations.
✓ Designed for integration within Woodward marine control architectures; compatibility with specific panels, controllers, or power management systems should be confirmed against vessel documentation and system version.
✓ Revision F designation indicates an updated production standard; always verify revision level against existing installation drawings or OEM documentation before replacement to ensure dimensional and functional compatibility.
Marine Applications
✓ Vessel power management systems (PMS) requiring accurate AC voltage and current monitoring across generator sets and main switchboards.
✓ Main and emergency switchboard panels on commercial cargo vessels, tankers, bulk carriers, and offshore support vessels where Woodward control systems are installed.
✓ Engine control room instrumentation panels where generator load sharing and power distribution monitoring are essential for safe vessel operation.
✓ Offshore platforms and drill ships utilising Woodward-based automation for generator synchronisation and electrical network supervision.
✓ Naval auxiliaries, ferries, and cruise vessels requiring precise electrical signal transduction as part of integrated automation and alarm monitoring systems.
Why Marine Engineers Choose
Marine engineers and electrical officers specify the Woodward UMT1 for its dependable signal accuracy, compatibility with established Woodward control architectures, and its robust tolerance to the wide temperature variations and electrical noise environments typical of shipboard installations — making it a trusted component for both planned maintenance and critical fault rectification.
Ideal For
Commercial cargo ships, tankers, bulk carriers, offshore support vessels, drill ships, ferries, and any vessel class operating Woodward-based power management or engine control systems requiring AC measuring transducer replacement or upgrade.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, testing and commissioning, and retrofit or integration projects involving this transducer — subject to confirmation of installation context and system configuration. To confirm compatibility and suitability, buyers are advised to share nameplate photographs, the full part number and revision level, relevant system drawings or wiring diagrams, the control system model and software version, and vessel name or IMO number where applicable. All compatibility and application assessments are subject to confirmation based on documentation provided.
