Long-term Stability for Reduced Maintenance Requirements

One of the most remarkable attributes of the YOKOGAWA EJA110E is its outstanding long-term stability, rated at ±0.1% URL (Upper Range Limit) over a 10-year period. This exceptional stability significantly reduces the frequency of recalibration and maintenance interventions, resulting in lower operational costs and minimized process interruptions. The stability of the YOKOGAWA EJA110E Differential Pressure Transmitter stems from its robust design, premium materials, and advanced manufacturing techniques that minimize the effects of aging, temperature cycling, and mechanical stress. For industrial operations where continuous uptime is paramount, this stability translates to greater process reliability and reduced total cost of ownership. Additionally, the transmitter's resilience to overpressure events—with an influence rating of only ±0.03% URL—further ensures measurement integrity even during process upsets or abnormal conditions. This combination of long-term stability and overpressure resistance makes the YOKOGAWA EJA110E an ideal choice for applications where maintenance access is limited or where process continuity is critical to operational success.

Rapid Response for Dynamic Process Control

In fast-paced industrial environments, the ability to respond quickly to changing process conditions is essential for maintaining control and preventing unwanted excursions. The YOKOGAWA EJA110E excels in this regard with an impressive response time of just 90 milliseconds for the primary variable (differential pressure), while also providing static pressure measurements with a response time of 360 milliseconds. This rapid response capability ensures that control systems receive timely process information, enabling more precise control actions and tighter process management. For applications involving batch processing, flow control, or other dynamic conditions, the YOKOGAWA EJA110E Differential Pressure Transmitter provides the responsiveness necessary to maintain product quality and process efficiency. The combination of fast response and exceptional accuracy enables more sophisticated control strategies that can optimize resource utilization, reduce energy consumption, and improve overall process performance. Industries dealing with rapid process changes, such as chemical reactions or turbulent flow conditions, particularly benefit from the EJA110E's ability to capture and communicate pressure fluctuations with minimal lag time, ensuring that process control decisions are based on the most current and accurate information available.

Multi-variable Measurement Capabilities

Modern industrial operations demand more information from fewer instruments to optimize space utilization, reduce installation costs, and simplify maintenance requirements. The YOKOGAWA EJA110E excels in this regard by providing multi-variable measurement capabilities. While primarily designed for differential pressure measurement, the transmitter simultaneously monitors static pressure, delivering two critical process parameters from a single instrument. This dual measurement capability makes the YOKOGAWA EJA110E Differential Pressure Transmitter particularly valuable in flow applications where both differential pressure (for flow calculation) and line pressure (for compensation or monitoring) are required. The static pressure measurement, while offering slightly lower accuracy (±0.5%) than the primary differential pressure measurement, still provides valuable process information that would otherwise require additional instruments. For applications such as filtered flow measurement, tank level monitoring with pressure compensation, or density determination, the EJA110E's multi-variable capability simplifies installation, reduces potential leak points, and provides a more comprehensive view of process conditions. This integrated approach to measurement not only reduces hardware costs but also minimizes maintenance requirements and improves overall system reliability by reducing the total number of instruments and connections in the process.
