Superior Accuracy and Stability for Critical Applications

Industry-Leading Measurement Precision

The YOKOGAWA EJA110E sets a new standard in measurement accuracy with its impressive ±0.055% reference accuracy for differential pressure measurements, with an optional enhanced accuracy of ±0.04% available for applications requiring the utmost precision. This exceptional level of accuracy is made possible by the advanced monocrystalline silicon resonant sensor technology at the heart of the YOKOGAWA EJA110E Differential Pressure Transmitter. In practical terms, this means that industrial processes requiring exact pressure measurements – such as in pharmaceutical manufacturing, food processing, or chemical production – can operate with greater confidence and consistency. The transmitter's ability to maintain this accuracy across a wide measurement range makes it particularly valuable in applications where both low and high pressure measurements must be taken with equal reliability, eliminating the need for multiple instruments and simplifying system architecture while improving overall measurement integrity across your operational processes.

Unmatched Long-term Stability

Long-term stability is a critical factor in industrial instrumentation, and the YOKOGAWA EJA110E excels with its remarkable stability rating of ±0.1% URL over a 10-year period. This exceptional stability translates to fewer calibration requirements, reduced maintenance costs, and more consistent process control over the transmitter's operational lifetime. For facilities operating continuous processes, the YOKOGAWA EJA110E's stability means less downtime for instrument adjustments and greater confidence in measurement data over extended periods. The practical implications of this stability include improved product consistency, more reliable regulatory compliance documentation, and lower total cost of ownership. Plant operators can rely on the transmitter's readings year after year without the frequent recalibrations typically required with less stable instruments, making the YOKOGAWA EJA110E an ideal choice for installations where maintenance access is difficult or where process continuity is paramount.

Remarkable Range Capability

The YOKOGAWA EJA110E features an impressive 100:1 range ratio for its principal variable measurements, providing exceptional flexibility across various applications. This wide rangeability allows a single transmitter to handle a broad spectrum of measurement scenarios, reducing inventory requirements and simplifying specification processes for engineering teams. In practical applications, this means the YOKOGAWA EJA110E Differential Pressure Transmitter can accurately measure both very low and very high pressure differentials within the same process or across different operational modes. This capability is particularly valuable in batch processing operations where conditions vary significantly between production phases, or in applications where seasonal or product-dependent changes affect process parameters. By maintaining accuracy across such a wide measurement span, the transmitter eliminates the need for range changes or instrument swaps, contributing to more streamlined operations and improved process reliability regardless of operating conditions.

Enhanced Operational Performance Features

Rapid Response for Dynamic Processes

The YOKOGAWA EJA110E delivers exceptional performance with its lightning-fast response time of just 90 milliseconds for the primary variable, making it ideal for applications requiring real-time monitoring and control. This rapid response capability ensures that even the most dynamic pressure changes are captured accurately, providing operators with immediate awareness of process variations and enabling faster corrective actions when necessary. In high-speed manufacturing environments, the YOKOGAWA EJA110E Differential Pressure Transmitter's quick response can be the difference between maintaining product quality and experiencing costly production issues. The transmitter's auxiliary variable (static pressure) measurement response time of 360 milliseconds complements its primary capabilities, providing comprehensive pressure monitoring with minimal delay. This performance characteristic is particularly valuable in applications like turbine monitoring, compressor control, or any process where pressure fluctuations occur rapidly and require immediate detection and response to prevent equipment damage or process disruption.

Robust Overpressure Protection

The YOKOGAWA EJA110E is engineered to withstand challenging industrial conditions, with outstanding resistance to overpressure events. Its minimal influence of overpressure rating of ±0.03% URL ensures measurement integrity even when the transmitter experiences pressure spikes beyond normal operating conditions. This robust design is complemented by a maximum working pressure capability of 2,300 psi, with an optional upgrade to 3,600 psi for more demanding applications. The YOKOGAWA EJA110E Differential Pressure Transmitter's ability to maintain measurement accuracy and physical integrity during overpressure events significantly reduces the risk of instrument damage and process interruptions. For industries dealing with variable pressure conditions or potential pressure surge events, this resilience translates to enhanced equipment longevity, improved process reliability, and reduced risk of unplanned downtime due to instrument failure, making it an ideal choice for critical installations where pressure fluctuations are a concern.

Advanced Safety Certifications

Safety is paramount in industrial environments, and the YOKOGAWA EJA110E delivers with its comprehensive certification package, including TÜV and Exida SIL 2/SIL 3 certifications. These internationally recognized safety integrity level certifications validate the transmitter's suitability for use in safety-instrumented systems where reliable performance is essential for risk reduction. The YOKOGAWA EJA110E Differential Pressure Transmitter's compliance with these rigorous standards provides assurance that it can be deployed in safety-critical applications with confidence. This certification is particularly valuable in industries such as oil and gas, chemical processing, and power generation, where pressure measurement can be directly linked to process safety. By incorporating transmitters with verified safety performance metrics, system designers can achieve required risk reduction levels while maintaining measurement accuracy and reliability. The dual certification for both SIL 2 and SIL 3 applications provides flexibility in system design and implementation, allowing the YOKOGAWA EJA110E to be deployed across various safety function requirements.
