Product Description

Product Description

Product Overview and Advantages

The Yokogawa EJA430E Pressure Transmitter is a high-performance differential pressure and level transmitter designed for industrial applications requiring exceptional accuracy, reliability, and durability. Built on Yokogawa's advancedSingle-Crystal Silicon Resonant Sensortechnology, the EJA430E delivers precise measurement of differential pressure, liquid level, and flow in demanding environments. It is widely used in industries such as oil and gas, chemical processing, power generation, and water treatment. The transmitter's robust construction ensures reliable operation in extreme conditions, including high temperatures, high static pressures, and corrosive media. With its modular design and user-friendly configuration, the EJA430E simplifies installation and maintenance while meeting global safety and quality standards.

Core Technology and Measurement Excellence

The EJA430E's standout feature is itsSingle-Crystal Silicon Resonant Sensor, which achieves unmatched stability and accuracy (±0.03% of span). This sensor technology minimizes drift caused by temperature fluctuations, vibration, or mechanical stress, ensuring consistent performance over time. The device employs Yokogawa's proprietaryDPharp (Differential Pressure Harmonic Sensor)design, where twin resonators detect pressure changes with high sensitivity. This dual-resonator approach cancels out external noise and provides built-in temperature and static pressure compensation. Additionally, the EJA430E supports digital communication protocols like HART®, BRAIN®, and FOUNDATION Fieldbus™, enabling seamless integration into modern industrial automation systems. Its adaptive signal processing enhances response speed and diagnostic capabilities, making it ideal for dynamic process control.

Design Advantages for Harsh Environments

Design Advantages for Harsh Environments

Engineered for resilience, the EJA430E excels in challenging operating conditions. Its compact, corrosion-resistant housing is constructed from 316L stainless steel or Hastelloy® alloys, ensuring compatibility with aggressive media. The transmitter's IP67/IP68 ingress protection rating and explosion-proof certifications (ATEX, IECEx, FM) make it suitable for hazardous areas. Unique features likeAdvanced Dual-Layer Diaphragm Sealsprevent clogging in viscous or slurry applications, while aSilicon Oil Filling Systemenhances thermal stability.

The EJA430E also incorporates Yokogawa'sSelf-Diagnostic Suite, which detects abnormalities such as sensor malfunctions, wiring faults, or process leaks, reducing unplanned downtime. Its modular components allow quick replacement of electronics or sensor modules without recalibration, minimizing maintenance costs and operational disruptions.

Operational Efficiency and Cost Benefits

The EJA430E optimizes total cost of ownership through energy-efficient operation and long-term reliability. Its low power consumption aligns with sustainability goals, while a five-year calibration interval reduces lifecycle costs. The transmitter'sDynamic Response Tuningfeature allows users to adjust response times for specific processes, balancing speed and stability. By providing precise data for predictive maintenance and process optimization, the EJA430E enhances plant efficiency and safety. Case studies in refineries and chemical plants demonstrate its ability to reduce measurement errors by up to 50% compared to conventional transmitters. With global technical support and Yokogawa's reputation for quality, the EJA430E remains a trusted solution for critical pressure and level measurement challenges.

Specification

Step	Procedure
1	Unpacking & Inspection: Check package contents against shipping list. Inspect for physical damage during transit.
2	Mounting: Install on vertical process pipe or horizontal manifold. Use appropriate brackets (model AB201/AB202). Ensure process connection matches transmitter thread (e.g., 1/2″ NPT, G1/2).
3	Orientation: Align transmitter housing to rotate ±90° for optimal local indicator visibility. Avoid mounting with diaphragm position facing downward.
4	Sealing: Apply sealant (e.g., PTFE tape) to male threads. Tighten with proper torque (20 N·m max for 1/2″ NPT).
5	Electrical Connection: Use 1/2″ NPT conduit entry. Connect power (10.5–42 V DC) to terminals [+] and [-]. Ensure proper grounding via dedicated ground terminal.
6	HART Communication: Connect HART communicator (e.g., YHC5150) in parallel with 250–600Ω resistor for loop configuration.
7	Configuration: Set measurement range via local buttons or HART using parameters: LRV (4mA), URV (20mA). Enable damping if required (0–100 sec).
8	Pressure Testing: Apply 1.5× rated pressure for hydrostatic test. Check for leaks with soap solution.
9	Calibration: Perform zero/span calibration using digital trim function. Verify 4–20mA output corresponds to applied pressure.
10	Startup: Gradually pressurize system. Monitor output signal stability (±0.075% of span).
