Reduced-pressure cooling station equipped with Yokogawa VY series vortex flowmeter and EJAC60E sanitary pressure transmitter

The Yokogawa EJAC60E represents a significant advancement in pressure measurement technology as a multi-sensor pressure transmitter designed for extreme process conditions and critical applications. This sophisticated instrument combines multiple sensing technologies in a single unit, providing unparalleled measurement capabilities for demanding industrial environments. The EJAC60E is engineered to deliver exceptional performance in industries where precise pressure measurement is crucial for process efficiency, safety, and reliability, including oil and gas production, refining, chemical processing, and power generation.

The EJAC60E incorporates Yokogawa's innovative multi-sensor design that simultaneously measures differential pressure, static pressure, and process temperature. This integrated approach provides comprehensive process information while eliminating the need for multiple separate instruments. The heart of the transmitter features Yokogawa's proven single-crystal silicon resonant sensor technology, which ensures outstanding accuracy of up to ±0.04% for differential pressure measurements and ±0.1% for static pressure measurements. This technology utilizes a unique resonating element that changes frequency proportionally to applied pressure, offering exceptional stability and repeatability even under extreme conditions. The multi-sensor configuration enables advanced compensation algorithms that automatically correct for temperature and static pressure effects, ensuring accurate measurements across the entire operating range.

The transmitter is built to withstand the most challenging industrial environments, featuring a heavy-duty, all-welded stainless steel construction with IP67 and NEMA 4X protection. The EJAC60E operates reliably across an extensive temperature range from -50 to 120°C and handles maximum working pressures up to 42 MPa. Its robust design includes exceptional resistance to vibration, shock, and electromagnetic interference, making it suitable for installation in remote or hazardous locations. The device offers multiple process connection options and diaphragm materials, including Hastelloy, titanium, and other exotic alloys, ensuring compatibility with corrosive and abrasive media. The transmitter's compact yet durable design facilitates easy installation while maintaining performance in space-constrained applications.

The EJAC60E is equipped with Yokogawa's enhanced Heartbeat Technology, which provides continuous self-diagnostics and verification of measurement integrity without process interruption. This feature supports predictive maintenance strategies and helps ensure compliance with safety standards. The transmitter supports multiple digital communication protocols including HART, BRAIN, FOUNDATION Fieldbus, and PROFIBUS PA, offering seamless integration into various control systems. The unit features a large, rotatable LCD display with multiple language support and intuitive local operation interface. Advanced software capabilities include built-in flow computation functions, density compensation, and custom characterization curves, reducing the need for additional computing devices in the control system.

The EJAC60E is particularly valuable in applications requiring precise mass flow measurement, such as natural gas custody transfer, where its multi-sensor capability provides temperature and pressure compensated flow calculations. It excels in critical process applications including reactor pressure monitoring, distillation column control, and high-pressure steam measurement. The transmitter meets rigorous international standards and holds SIL 2/SIL 3 certification according to IEC 61508/61511 for safety instrumented systems. It also carries ATEX, IECEx, and other hazardous area certifications, ensuring safe operation in potentially explosive environments. The device's comprehensive diagnostic capabilities and proven reliability make it an ideal choice for applications demanding minimal maintenance and maximum operational availability while maintaining the highest levels of measurement accuracy and process safety.
