Why Choose Yokogawa EJA110E High Performance Differential Pressure Transmitter?

In industrial process control where measurement accuracy directly impacts operational efficiency and profitability, choosing the right differential pressure transmitter becomes critical. The Yokogawa EJA110E high performance differential pressure transmitter addresses the persistent challenges faced by process engineers: inaccurate readings during process upsets, frequent recalibration requirements, extended downtime during maintenance, and inadequate diagnostic capabilities that lead to unexpected failures. This advanced instrument delivers exceptional precision with monocrystalline silicon resonant sensor technology, offering 0.055% reference accuracy and remarkable 10-year stability that eliminates costly measurement errors in critical applications across chemical processing, oil and gas, power generation, and water treatment facilities.

Superior Measurement Technology and Digital Performance

The Yokogawa EJA110E high performance differential pressure transmitter represents a significant technological advancement in pressure measurement, utilizing proprietary DPharp (Differential Pressure High Accuracy Remote sensor with Protocol) digital sensor technology. Unlike conventional analog sensors that require analog-to-digital conversion introducing additional measurement errors, the DPharp sensor directly outputs a digital signal from the monocrystalline silicon resonant element. This fundamental design principle eliminates conversion errors and delivers twice the performance and stability compared to traditional analog pressure sensors available in the market. The single crystal silicon resonant sensor at the heart of the Yokogawa EJA110E high performance differential pressure transmitter operates on a resonant frequency principle, where pressure changes affect the resonant frequency of precision-machined silicon beams. This digital measurement approach provides inherent noise immunity and superior long-term stability of ±0.1% URL over 10 years, significantly reducing calibration frequency and associated maintenance costs. The sensor's linkage-less feedback mechanism minimizes mechanical wear, ensuring consistent performance throughout its operational lifetime while measuring differential pressure ranging from 0.5 kPa to 14 MPa across five different capsule configurations.

Advanced Multi-Variable Measurement Capabilities

The Yokogawa EJA110E high performance differential pressure transmitter uniquely integrates three measurement capabilities within a single sensor: differential pressure as the principal variable, static pressure as an auxiliary variable, and capsule temperature monitoring. This multi-sensing capability enables dynamic compensation for both temperature effects and static pressure effects that typically degrade measurement accuracy in conventional transmitters. The transmitter automatically corrects differential pressure readings in real-time based on actual process conditions, maintaining specified accuracy across wide operating ranges without manual intervention or complex external compensation systems. This integrated approach delivers substantial operational benefits beyond basic pressure measurement. The static pressure measurement capability allows the Yokogawa EJA110E high performance differential pressure transmitter to provide complete process visibility with a 100:1 turndown ratio, supporting applications from precise flow measurement using orifice plates to level measurement in pressurized vessels. The 90-millisecond response time for differential pressure and 360-millisecond response time for static pressure enable fast control loop response, critical for maintaining process stability during dynamic operating conditions in continuous manufacturing processes.

Exceptional Accuracy and Long-Term Stability

Measurement accuracy represents the foundation of effective process control, and the Yokogawa EJA110E high performance differential pressure transmitter sets industry-leading standards with reference accuracy of ±0.055% of span, with an optional high-accuracy configuration achieving ±0.04%. This precision level enables tighter process control, reduces product quality variations, and minimizes waste in critical applications where small measurement deviations translate to significant operational costs. The accuracy specification encompasses terminal-based linearity, hysteresis, and repeatability, ensuring consistent performance across the full measurement span under varying process conditions. Long-term stability distinguishes the Yokogawa EJA110E high performance differential pressure transmitter from conventional instruments that experience measurement drift requiring frequent recalibration. The DPharp digital sensor maintains ±0.1% URL stability over 10 years, dramatically extending calibration intervals and reducing maintenance requirements. This exceptional stability results from the monocrystalline silicon sensor construction, which exhibits minimal material property changes over time, and the digital signal processing that eliminates drift associated with analog electronic components found in traditional transmitter designs.

Robust Overpressure Protection and Operational Resilience

Process upsets, incorrect valve sequencing during startup, and emergency shutdown scenarios frequently expose pressure transmitters to overpressure conditions exceeding their specified operating range. The Yokogawa EJA110E high performance differential pressure transmitter withstands maximum working pressure up to 2,300 psi (with optional 3,600 psi rating) and demonstrates remarkable resilience during overpressure events. When subjected to pressures exceeding the sensor's upper range limit, the transmitter automatically returns to specified accuracy and stability once normal operating conditions resume, eliminating the need for recalibration or replacement that analog sensors require after overpressure exposure. This overpressure resilience provides critical operational advantages in real-world industrial environments. Process engineers can specify the Yokogawa EJA110E high performance differential pressure transmitter with confidence that measurement integrity will be maintained through process transitions, equipment malfunctions, and operator errors that would damage conventional transmitters. The robust sensor design combined with advanced diagnostics detects and reports overpressure events, enabling proactive maintenance planning while maintaining continuous measurement capability throughout the incident, enhancing overall plant safety and reliability.
