Product Description

Product Description

YOKOGAWA Differential Pressure Transmitter EJX110A

The high performance diff erential pressure transmitter EJX110A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam fl ow as well as liquid level, density and pressure. EJX110A outputs a 4 to 20 mA DC signal corresponding to the measured diff erential pressure.
Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response, remote set-up using communications, diagnostics and optional status output for pressure high/low alarm.

The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage.

FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available. All EJX series models in their standard confi guration, with the exception of the Fieldbus and PROFIBUS types, are certifi ed as complying with SIL 2 for safety requirement

Features

The EJX-A series is Yokogawa's premium performance line of DPharp transmitters. Released in 2004, it offers the performance and stability needed in demanding applications. The EJX-A series performance makes it the thoroughbred of the DPharp family of pressure transmitters.

The EJX110A is the traditional-mount Differential Pressure Transmitter in the series.

EJX110A features include:

± 0.04% Accuracy (0.025% Accuracy option available)
± 0.1% per 15 years Stability
90 ms Response Time
3,600 psi MWP
Exida and TUV SIL2 / SIL3 Certified
Local Parameter Setting (LPS)

Application

Chemical processing: Monitoring pressure differences in reaction vessels, pipelines, and filtration systems.
Oil and gas: Measuring flow rates in pipelines, differential pressure across valves, and tank level via hydrostatic pressure.
Power generation: Controlling steam pressure in boilers, condenser differential pressure, and cooling water flow.
Water and wastewater treatment: Monitoring filter differential pressure and pump performance.
Food and pharmaceutical industries: Sanitary applications requiring accurate and hygienic pressure measurement 

Specification

Item	valve
Type	Gauge pressure transmitter
Measuring Range	Gauge pressure: 0–100 Pa to 0–40 MPa (varies by model; specific ranges include 0–1 kPa, 0–10 kPa, 0–100 kPa, 0–1 MPa, 0–10 MPa, 0–40 MPa, etc.)
Accuracy	±0.065% of calibrated span (including linearity, hysteresis, and repeatability) under reference conditions: temperature 15–35°C (59–95°F), static pressure 0 MPa, and ambient pressure 0.1 MPa
Stability	±0.1% of URL (Upper Range Limit) per 5 years
Output Signal	- Standard: 4–20 mA DC with HART® 7 protocol (two-way digital communication, superimposed on the analog signal) - Optional: FOUNDATION Fieldbus (low-voltage mode) or PROFIBUS PA (conforms to IEC 61158-2 and EN 50170 standards)
Sensor Technology	Monocrystalline silicon resonant sensor; converts pressure into high-frequency resonant signals (≈10 kHz) for digital processing, minimizing drift and interference
