The Original Yokogawa EJA110E is a high-performance differential pressure transmitter, also functioning as a gauge pressure transmitter, designed for industrial process measurement. It is engineered to measure the pressure or level of industrial liquids and gases, transmitting the measurement output signal to control systems to ensure safe, reliable, and profitable operation of customer plants.

Part of Yokogawa's DPharp family, this transmitter excels in harsh environments—from offshore platforms to desert refineries—delivering accurate, repeatable measurements even at high altitudes. Its compact, lightweight, and robust design simplifies installation, commissioning, operation, and maintenance. With support for digital communication protocols like FOUNDATION™ Fieldbus and PROFIBUS PA, it integrates seamlessly into modern instrument control systems, replacing traditional 4-20 mA analog communication for enhanced flexibility.

• Exceptional Accuracy: Boasts high accuracy of ±(0.005 + 0.02 URL/span)% of span, with an excellent performance variant offering 0.075% accuracy, ensuring precise measurement for critical processes.
• Wide Measurement Ranges: Differential pressure ranges from 0-25Pa to 13.8MPa. Gauge pressure ranges from 0-0.12kPa to 13.8MPa (model-specific range: 0.5-14MPa). Absolute pressure ranges from 0-2kPa to 27.6MPa.
• High Rangeability: Offers a 100:1 range ratio, providing flexibility to cover multiple measurement scenarios with a single device.
• Durable Materials: Equipped with process isolation diaphragms made of stainless steel, Hastelloy C, Monel, Tantalum (CD, CG), and gold-plated Monel.
• Compact and Robust Design: Small, strong, and lightweight, facilitating easy installation in space-constrained environments.
• Advanced Communication: Supports FOUNDATION™ Fieldbus low voltage mode and PROFIBUS PA, enabling bidirectional digital communication.
• Easy Commissioning: Compatible with the BT200 hand operator for on-site communication (requires 250-600 ohm resistance in the loop).
• Wide Operating Temperature: Functions within an operating temperature range of -20~80°C.
• Versatile Output: Provides a 4-20 mA output, ensuring compatibility with traditional analog control systems.
