Single crystal silicon legend, new benchmark for precise pressure measurement: Yokogawa EJA510E/EJA530E absolute/gauge p

In the field of pressure measurement, Yokogawa Electric's EJA series has long been synonymous with stability, accuracy, and reliability. Its core single crystal silicon resonant sensor technology has provided countless excellent measurement data without drift and hysteresis for the global industry. Xi'an Xinyi Instrument Technology Co., Ltd. brings you the enhanced force series - Yokogawa EJA510E (absolute pressure) and EJA530E (gauge pressure) pressure transmitters. These two instruments inherit the legendary single crystal silicon technology lineage of the EJA series, setting a new performance benchmark for precise measurement of liquid, gas, or vapor pressure in industries such as petroleum, chemical, power, and pharmaceuticals with their high measurement accuracy of ± 0.055%, extraordinary stability of ± 0.1%/12 months, 100:1 range ratio, and powerful SIL 2 safety certification.

• 1. Core technology: Monocrystalline silicon resonant sensor, ensuring precision from the source

  The heart of EJA510E/530E is Yokogawa's proud monocrystalline silicon resonant sensor. Monocrystalline silicon, as an ideal elastic material, has an extremely uniform molecular structure and almost no hysteresis phenomenon under pressure and temperature changes. This fundamental material advantage enables sensors to minimize overvoltage impact, temperature fluctuations, and static pressure effects, providing unparalleled long-term stability and ensuring that the transmitter can output true and reliable signals throughout its entire lifecycle.

• 2. Excellent performance: high precision and wide range coverage

  Thanks to advanced sensor and signal processing technology, the measurement accuracy of the EJA530E gauge pressure transmitter can reach ± 0.055%, while the EJA510E absolute pressure transmitter also has excellent accuracy of ± 0.2%. Its measurement range covers a wide area from 10kPa to 50MPa, which can flexibly meet various needs from micro pressure measurement to ultra-high pressure conditions. At the same time, the product has excellent 12-month long-term stability (± 0.1% range limit), significantly reducing the need for regular calibration and maintenance costs.

• 3. Intelligent Communication and Functional Safety

  Both transmitters come standard with 4-20mA HART protocol digital communication and can be optionally equipped with multiple protocols such as BRAN, FOUNDATION fieldbus, PROFIBUS PA, etc., enabling seamless integration into various mainstream control systems. Its powerful self diagnostic function can monitor the status of the transmitter in real time. More importantly, the standard configuration of the EJA-E series has been certified and meets SIL 2 safety requirements, making it highly reliable for use in critical safety instrument function circuits such as emergency stop systems.

• 4. Compact design and rich materials

  By integrating the amplifier ASIC, pressure unit structure, and flange into a micro design, the volume and weight of the transmitter are reduced by about 50% compared to traditional models, making installation more convenient. We offer a variety of isolation membrane materials such as stainless steel, Hastelloy, Monel, etc., tailored to the corrosiveness of different media. With a temperature range of -40 to 120 ℃, we ensure long-term stable operation under harsh working conditions.
