The Yokogawa EJX440A High-performance Pressure Transmitter gives you very accurate pressure readings in tough industrial settings. This high-tech tool uses a new resonance sensing technology with single-crystal silicon that has already been shown to work. You will get the long-term security and better measurement accuracy that your important processes need. This transmitter makes sure that it always works the same way, even when things get tough. It doesn't matter if you're using it for oil, petrochemicals, or power generation.

Unmatched Accuracy for Your Operations
You'll get the most accurate reading in the business, with reference accuracy of ±0.04%. The modern DPharp digital sensor technology can keep an eye on things all the time in a way that older sensors can't. With this amount of data confidence, you can trust your process control more.
Built to Last in Harsh Environments
The robust construction protects your investment for years to come. You get four-bolt pressure retention design and Teflon-coated 316L stainless steel components. This means fewer maintenance interruptions and lower total cost of ownership. The transmitter withstands extreme conditions while maintaining measurement integrity.
Smart Diagnostics Save You Time
Real-time self-monitoring helps prevent unexpected downtime. The patented Back-Check system continuously verifies measurement accuracy. You'll know immediately if any issues arise, allowing proactive maintenance instead of reactive repairs.

Advanced Overpressure Protection
Your equipment stays protected even during unexpected pressure events. The mechanical design provides multiple layers of protection against valve operation errors and pressure surges. This means fewer equipment failures and reduced maintenance costs.
Safety Certified Performance
You can trust third-party verified reliability from TÜV Rheinland and EXIDA. The transmitter meets SIL2 requirements as a single unit and SIL3 when used redundantly. This eliminates the need for additional safety equipment in many applications.
Fast Response Technology
The Yokogawa EJX440A High-performance Pressure Transmitter's quick 90-millisecond response time ensures your control systems react promptly to process changes. You'll maintain tighter process control and improve product quality consistency.
Extended Range Capability
The impressive 200:1 range ratio provides flexibility across various operating conditions. You can use fewer transmitter models to cover multiple applications, simplifying inventory management.
Petroleum and Gas Processing
Monitor pipeline pressures, vessel levels, and flow measurements with confidence. The transmitter's stability ensures accurate readings even with temperature fluctuations and vibration.
Chemical Manufacturing
Track reactor pressures and distillation column operations reliably. The corrosion-resistant materials handle aggressive chemical environments without degradation.
Power Generation
Maintain boiler pressure monitoring and steam system control with precision. The fast response time supports critical safety and efficiency requirements.
You'll appreciate the straightforward installation process. Standard mounting configurations fit existing infrastructure easily. The 4-20mA output integrates seamlessly with most control systems. Remote configuration capabilities reduce commissioning time significantly.
Reduced Maintenance Requirements
The stable design minimizes drift and calibration needs. You'll spend less time on routine maintenance and more on productive operations.
Extended Service Life
Fifteen-year stability specifications mean longer intervals between replacements. Your capital equipment budget stretches further with this reliable solution.
