Turbine & Generator Control Solution — WOODWARD 8444-1002 | Measuring Transducer
The WOODWARD 8444-1002 Measuring Transducer is a precision signal-conditioning module engineered for industrial prime-mover control systems. Designed to interface with WOODWARD’s governor and control platforms, it converts raw sensor inputs—speed, load, pressure, or temperature—into clean, calibrated analog signals that drive closed-loop control decisions in real time. For engineers specifying replacement or upgrade components in turbine, generator, and compressor applications, the 8444-1002 is a proven, OEM-grade solution available through Konmask.com.
Where This Product Is Used
- Steam Turbine Governor Systems — Provides accurate speed and load feedback to WOODWARD 505, 505E, and MicroNet governor controllers, enabling stable isochronous or droop speed control across load transients.
- Gas Turbine Control Panels — Conditions fuel-flow and exhaust-temperature sensor signals for integration into turbine management systems in power generation and oil & gas facilities.
- Diesel & Gas Generator Sets — Used in genset paralleling applications where precise load-sharing signals are required between multiple generating units on an islanded or grid-tied bus.
- Industrial Compressor Drives — Interfaces with pressure and flow transmitters to deliver conditioned process-variable signals to WOODWARD speed controllers in pipeline compression stations.
- Marine Propulsion Control — Deployed in ship propulsion governor panels where vibration-resistant, reliable signal conditioning is mandatory for classification society compliance.
- Hydroelectric Turbine Governors — Converts wicket-gate position and shaft-speed sensor outputs into standardized signals for WOODWARD digital governor platforms.

Application-Specific FAQ
Q: Is the WOODWARD 8444-1002 a direct replacement for older 8444-series transducers?
A: In most cases, yes. The 8444-1002 is pin- and signal-compatible with other 8444-series variants used in WOODWARD governor panels. We recommend confirming your existing wiring diagram before installation. Contact us for a compatibility check.
Q: Can this transducer be used with non-WOODWARD control systems?
A: The 8444-1002 outputs a standard analog DC signal and can interface with third-party PLCs or DCS systems provided the input impedance and signal range are matched. Signal scaling may be required.
Q: What is the lead time for the 8444-1002?
A: Stock availability varies. In-stock units ship within 3–5 business days. For out-of-stock items, typical lead time is 4–8 weeks. Submit an RFQ for current availability.
