Original Yokogawa Eja130e Differential Pressure Transmitter

YOKOGAWA Differential Pressure Transmitter EJA130E

The high performance diff erential pressure transmitter EJA130E features single crystal silicon resonantsensor and is suitable to measure liquid, gas, or steam fl ow as well as liquid level, density and pressure. EJA130E outputs a 4 to 20 mA DC signal corresponding to the measured diff erential pressure.
Its 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 and self-diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available.

EJA-E series models in their standard confi guration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certifi ed as complying with SIL 2 for safety requirement.

Applications

Flow Measurement:
Measures DP across orifice plates, venturi tubes, or flow nozzles to calculate flow rates of liquids, gases, and steam.
Ideal for high-pressure pipelines in oil & gas, chemical, and power plants.

Level Measurement:
Uses hydrostatic principles to determine liquid levels in tanks or vessels under high pressure.
Critical in industries like wastewater treatment and petrochemicals.

Density Measurement:
Combines DP and static pressure data to calculate fluid density, essential for quality control in pharmaceuticals and food processing

General Pressure Monitoring:
Monitors static pressure in boilers, reactors, and hydraulic systems

Benefits

Unmatched Accuracy and Stability:
The DPharp sensor ensures ±0.055% accuracy and ±0.1% stability over 10 years, minimizing measurement errors and recalibration needs.Reduces process variability, improving product consistency and yield

Cost Efficiency:
Extended calibration intervals (up to 10 years) lower maintenance costs by 33%.Multi-sensing capability allows a single transmitter to provide DP, static pressure, and sensor temperature, reducing capital expenditure by 20%

Reliability and Safety:
SIL 2/3 certification ensures compliance with safety standards for hazardous environments.
Active sensor technology and 40+ self-diagnostic functions (including patented back-check technology) detect faults proactively, minimizing downtime.
Rugged construction and overpressure protection reduce field failures by 200%.
