Woodward 8444-1019 – UMT 1 Measuring Transducer

Product Overview

The 8444-1019 is a Woodward UMT 1 measuring transducer designed for electrical measurement in generator and power-generation control systems. It provides six analog output channels for measured electrical quantities and is configured for a 100 VAC voltage input with a 1 A current transformer input. The UMT 1 platform is used to convert electrical measurements into proportional analog signals for controllers, monitoring systems, and supervisory equipment. Woodward’s product catalog identifies 8444-1019 as the UMT 1/A6 configuration for 100 VAC and 1 A input. The unit also provides pulse-output functionality for energy measurement applications. This makes it useful in generator synchronization, load-control, power monitoring, and legacy Woodward control installations. The exact input transformer configuration should be verified before replacement because other UMT variants use different voltage and current ranges.

Technical Specifications — 8444-1019

Woodward’s historical product catalog identifies 8444-1019 specifically as the UMT 1/A6 version for 100 VAC; /1 A measurement.

Key Features and Benefits — 8444-1019

• Six analog measurement outputs.
• 100 VAC voltage-measurement configuration.
• 1 A AC current-input configuration.
• 24 VDC auxiliary supply.
• Supports energy pulse measurement.
• Suitable for generator and electrical power monitoring.
• Compact Type 1 housing.
• Designed for integration with Woodward control equipment.
• Useful for maintaining legacy power-generation systems.

The input configuration is the key selection point. A UMT 1 designed for 400 VAC or 5 A current input should not be treated as an equivalent replacement.

Installation and Maintenance — 8444-1019

Before installation, verify the voltage transformer ratio, current transformer rating, 24 VDC auxiliary supply, output scaling, and connected monitoring or control equipment. Record the existing wiring and output assignments before removing the transducer.

During maintenance, inspect terminal connections, CT wiring, voltage-sensing circuits, auxiliary power, and analog output wiring. Never open-circuit an energized current-transformer secondary. Verify measurement scaling after replacement before returning the generator-control system to service.

Personally, I would verify the 100 VAC / 1 A input configuration first. That detail is more important than simply matching the UMT 1 model family.

Product Warranty — 8444-1019

Warranty coverage should be confirmed according to the supplied condition, such as new surplus, refurbished, repaired, or tested-used. For critical generator-control spares, procurement records should include the complete part number, revision, input configuration, inspection status, and warranty period.

When sourcing the Woodward 8444-1019, verify the UMT 1/A6 configuration, 100 VAC voltage input, 1 A current input, auxiliary supply, and analog-output requirements. Woodward provides a product-history lookup service that can be used to verify product information from the equipment label and part number.
