Product Description

Yokogawa EJA530E Differential Pressure Transmitter

The Yokogawa EJA530E Differential Pressure Transmitter is a high-performance industrial instrument designed to deliver precise and reliable pressure measurements in demanding environments. As part of Yokogawa's renowned EJA series, this transmitter combines advanced sensor technology, robust construction, and versatile communication capabilities to meet the needs of diverse process industries. Engineered for accuracy, durability, and ease of integration, the EJA530E is ideal for applications requiring real-time monitoring and control of differential pressure in liquids, gases, and steam.

Precision and Performance At the core of the EJA530E is Yokogawa's proprietary silicon resonant sensor, which ensures exceptional measurement accuracy and stability. This sensor employs a dual-vibrating element design that converts pressure differences into frequency signals, minimizing the impact of temperature fluctuations and mechanical stress. The transmitter offers a wide measurement range of up to 1,000 to 10,000 kPa (145 to 1,450 psi), with an accuracy of ±0.1% of span, making it suitable for both high-precision and general-purpose applications. Its fast response time of 0.2 seconds (for 90% step change) ensures timely data acquisition, critical for process optimization and safety.

Rugged Design and Environmental Tolerance Built to withstand harsh industrial conditions, the EJA530E features a rugged stainless steel housing with IP67/NEMA 4X ingress protection, ensuring resistance to dust, water, and corrosion. The transmitter operates reliably in extreme temperatures ranging from -40°C to 85°C (-40°F to 185°F) and can handle overpressure up to twice its maximum range without compromising performance. Its dual-seal system protects internal components from exposure to corrosive or viscous media, extending service life and reducing maintenance requirements.

Advanced Communication and Integration The EJA530E supports multiple digital communication protocols, including HART, Foundation Fieldbus, and PROFIBUS PA, enabling seamless integration into modern control systems. This compatibility allows for remote configuration, diagnostics, and data logging via asset management software, enhancing operational efficiency.

User-Friendly Features An intuitive local display module offers real-time pressure readings and diagnostic information, with a 4-digit LCD screen that can be rotated for optimal visibility. Configuration is simplified through push-button controls on the transmitter or via the HART protocol using a handheld communicator. The device supports multiple units of measurement (e.g., kPa, psi, bar, mmHg) and includes a simplified setup wizard for zero/SPAN adjustments and calibration. Additionally, its modular design allows for easy replacement of electronic and mechanical components, minimizing downtime during maintenance.

Safety and Compliance The EJA530E meets stringent global safety and quality standards, including FM, ATEX, IECEx, and CSA certifications for hazardous environments. It is rated for SIL 2 compliance under IEC 61508, ensuring reliability in safety-critical applications such as oil and gas exploration, chemical processing, and power generation. The transmitter's construction adheres to ISO 9001 and ISO 14001 standards, reflecting Yokogawa's commitment to sustainable and high-quality manufacturing.

Versatile Applications The EJA530E is widely used across industries for tasks such as monitoring pressure drop across filters, measuring liquid levels in tanks, controlling pumps, and managing flow rates via orifice plates or venturi tubes. Its adaptability extends to applications involving aggressive media, thanks to optional material upgrades (e.g., Hastelloy C-276 or tantalum wetted parts). In power plants, it ensures accurate boiler pressure monitoring, while in water treatment facilities, it aids in pipeline leak detection and filtration system optimization.

Energy Efficiency and Longevity With a low power consumption rating of 10.5–42 V DC loop supply, the EJA530E supports energy-efficient operations without sacrificing performance. Its long-term stability reduces the need for frequent recalibration, with a typical drift of less than 0.1% of span per year. This reliability translates to lower lifecycle costs and enhanced process uptime.
