Product Overview

The Woodward 9907-963 is a high-precision sensing node designed for gas turbine control systems. This state-of-the-art transducer captures manifold or fuel line pressure and converts it into a stable 4-20 mA analog signal. The real-time data provided to the turbine’s electronic control unit (ECU) ensures precise fuel metering, prevents over-pressure conditions, and optimizes combustion efficiency in demanding industrial environments.

Technical Specifications

Engineering Advantages

• Electromagnetic Interference (EMI) Shielding: The internal circuitry is designed with advanced EMI shielding, ensuring clean signal transmission even in the presence of high-voltage ignition systems or heavy-duty motors.

• High-Vibration Resilience: Utilizing a solid-state strain gauge design, the unit resists mechanical fatigue and maintains stability, even under extreme vibrations commonly found in turbine deck environments.

• Rapid Response Dynamics: The sensor reacts instantly to pressure fluctuations, allowing the control system to quickly adjust to surges or flame-out conditions, minimizing operational delays.

• Seamless Retrofitting: The 4-20 mA loop and NPT threading enable engineers to easily replace older sensors without needing modifications to existing piping or control systems.

FAQs

Does this unit require specialized calibration before installation?

• The 9907-963 is factory-calibrated by Woodward. However, technicians should perform a zero-point check via the control system interface after mounting to ensure accuracy in local conditions.

How does the 9907-963 handle corrosive fuel vapors?

• The transducer features a 316L stainless steel diaphragm and housing, which provides protection against corrosion caused by exposure to natural gas or liquid fuels.

Can this transducer operate in hazardous areas?

• The IP65 rating provides protection against dust and water ingress. However, engineers should check the unit’s specific hazardous zone certification (such as ATEX/IECEx) on the nameplate to ensure compliance with local safety standards.
