The monocrystalline silicon material used in the Yokogawa EJA110A differential pressure transmitter possesses unique properties that ensure zero hysteresis during pressure or temperature changes. This characteristic is critical for maintaining measurement accuracy over extended operating periods. Unlike traditional strain gauge sensors that can experience drift and degradation, the resonant sensor design minimizes the effects of overpressure events, temperature fluctuations, and static pressure variations. Since its introduction to the market, the Yokogawa EJA110A differential pressure transmitter has earned widespread recognition across multiple industries for its superior accuracy, stability, and reliability in demanding process control applications.

Core Measurement Capabilities and Applications

The EJA110A serves as a versatile measurement solution capable of monitoring level, density, and pressure across liquids, gases, and vapors in industrial processes. The transmitter converts measured differential pressure into a standardized 4-20 mA DC current signal output, ensuring compatibility with virtually all distributed control systems and process automation platforms. This analog output can be seamlessly integrated into existing control architectures, making the Yokogawa EJA110A differential pressure transmitter an ideal choice for both new installations and retrofit applications. Communication flexibility represents another key strength of the Yokogawa EJA110A differential pressure transmitter. The device supports multiple digital communication protocols including BRAIN, HART, FOUNDATION Fieldbus, and PROFIBUS PA. This multi-protocol capability enables remote configuration, diagnostics, and monitoring through various operator interfaces such as the BRAIN operator, CENTUM CS/μXL systems, or HART 275 communicators. Plant personnel can perform calibration adjustments, verify transmitter health, and access comprehensive diagnostic information without physical access to the field device, significantly reducing maintenance costs and minimizing process disruptions.

Measurement Range Flexibility for Diverse Applications

The Yokogawa EJA110A differential pressure transmitter offers five distinct measurement span options to accommodate various process requirements. The F span covers 0.5 to 5 kPa with a range of -5 to 5 kPa, suitable for low-pressure applications such as filter differential pressure monitoring and low-flow measurement. The L span extends from 0.5 to 10 kPa with a range of -10 to 10 kPa, providing versatility for small tank level measurement and ventilation system monitoring. The M span, ranging from 1 to 100 kPa with a range of -100 to 100 kPa, serves medium-pressure applications including pump differential pressure and standard flow measurement. For high-pressure processes, the H span offers 5 to 500 kPa with a range of -500 to 500 kPa, while the V span provides the widest range from 0.14 to 14 MPa with a range of -0.5 to 14 MPa, ideal for steam flow measurement and high-pressure vessel level monitoring. This comprehensive range selection ensures that the Yokogawa EJA110A differential pressure transmitter can be precisely matched to specific application requirements, optimizing measurement accuracy and turndown ratio. The ability to select the appropriate span eliminates the need to operate the transmitter at the extreme limits of its range, where accuracy typically degrades. By choosing the optimal span for each application, users maximize the performance capabilities of their Yokogawa EJA110A differential pressure transmitter investment.

Key Performance Benefits for Industrial Process Control
