Original Yokogawa Differential Pressure Transmitter EJA110E
Product Introduction
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.
Features
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.

of stainless steel, Hastelloy C, Monel, Tantalum (CD, CG), and
gold-plated Monel, ensuring compatibility with corrosive media and
extending service life.
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.
Uses two AI function blocks to calculate differential and static
pressures, enhancing configuration flexibility.
Easy Commissioning: Compatible with the BT200 hand operator for
on-site communication (requires 250-600 ohm resistance in the
loop); simplifies setup and calibration processes.
Wide Operating Temperature: Functions within an operating
temperature range of -20~80°C, adapting to various industrial
environmental conditions.
Versatile Output: Provides a 4-20 mA output, ensuring compatibility
with traditional analog control systems alongside digital
communication options.
