Woodward 8200-209 Pressure Transmitter

Product Dimensions：

Woodward is a renowned leader in the aerospace and industrial energy sectors, particularly known for high-precision control systems. Their pressure transmitters are designed to operate in the most demanding environments, providing critical data for turbine control, engine management, and fuel systems.

## Product Overview

Woodward pressure transmitters (often part of their 8200 series or specialized sensor lines) are high-performance, industrial-grade transducers. They are engineered to convert mechanical pressure from liquids or gases into precise electrical signals (typically 4-20 mA or CANbus). These devices are specifically “ruggedized” to withstand the high vibrations and extreme temperatures found in power generation and aviation.

## Key Technical Specifications

While specific models vary, most Woodward industrial transmitters share these core parameters:

• Output Signal: 4–20 mA DC, 0.5–4.5 VDC, or digital protocols (CANopen/SAE J1939).

• Pressure Ranges: Available from vacuum up to 10,000 psi (approx. 690 bar).

• Accuracy: Typically ±0.25% to ±0.1% of Full Scale (including linearity, hysteresis, and repeatability).

• Operating Temperature: $-40^circtext{C}$ to $+125^circtext{C}$ (with specialized models reaching higher for aero-engines).

• Supply Voltage: 9–32 VDC.

• Enclosure Rating: IP67 or IP6K9K (high-pressure washdown resistant).

• Material: 316L Stainless Steel or Inconel for corrosive media.

## Product Advantages

1. Extreme Durability: Built to survive the “on-engine” environment, resisting heavy vibration and thermal cycling that would cause standard industrial sensors to drift or fail.

2. Long-Term Stability: Advanced thin-film or piezo-resistive technology ensures minimal calibration drift over thousands of operating hours.

3. EMI/RFI Protection: High resistance to electromagnetic interference, crucial when mounted near high-output generators or ignition systems.

4. Compact Form Factor: Designed for easy integration into tight manifolds and engine compartments.

5. Certified Safety: Many models carry ATEX, IECEx, or UL certifications for use in hazardous (explosive) areas.

## Product Applications

Woodward transmitters are primarily used in high-stakes machinery control:

• Gas & Steam Turbines: Monitoring fuel skid pressure, lube oil pressure, and inlet air pressure.

• Reciprocating Engines: Measuring intake manifold pressure (MAP) and crankcase pressure.

• Compressor Control: Monitoring discharge pressure and surge protection systems.

• Hydraulic Systems: High-pressure monitoring for heavy-duty industrial actuators.

• Renewable Energy: Pitch control and braking systems in wind turbines.

## Important Considerations & Precautions

• Media Compatibility: Ensure the transmitter material (e.g., Stainless Steel) is compatible with the fluid being measured (e.g., sour gas, ammonia, or hydraulic fluid).

• Mounting Orientation: While most are vibration-resistant, mounting them away from direct heat sources can extend the lifespan of the internal electronics.

• Wiring Integrity: Use shielded twisted pair cabling to prevent signal noise, especially for the 4-20 mA loop.

• Pressure Spikes: Always select a sensor with a “Proof Pressure” rating that exceeds the maximum possible surge in your system to avoid diaphragm damage.
