Product Description

The  EJX310A  high-performance absolute pressure transmitter adopts monocrystalline silicon resonant sensing technology, which is  suitable for measuring the pressure of liquids, gases, or vapors. The  EJX310A  converts measured pressure into a 4-20mA DC current signal output, with functions such as fast response, remote  setting, and self diagnosis.

Core Advantages

1. Ultra-high Measurement Accuracy: The reference accuracy reaches **±0.075% (L-type capsule)**, and M/A/B-type      capsules can achieve up to **±0.04%**, meeting the requirements of high-precision process control.

2. Ultra-long Stability: Only ±0.2% URL drift over 15 years, greatly reducing calibration frequency and lowering      maintenance costs

3. Ultra-fast Response: 90ms rapid response, suitable for scenarios with dynamic pressure changes

4. Complete Safety Certifications: Certified by Exida and TÜV SIL2/3 functional safety standards, compliant with the      ANSI/ISA 12.27.01 double seal standard to ensure safety in high-risk operating conditions

5. Intelligent Diagnosis: Multi-sensing technology can predict impulse line blockage and heat tracing faults, provide      early warning of abnormalities, and reduce unplanned downtime.

Functional Features

1. DPharp Digital Sensing: Outputs digital signals directly without analog-to-digital conversion, minimizing errors      and enhancing measurement reliability.

2. 10-segment signal curve characterization: Supports nonlinear compensation and adapts to complex application      scenarios such as tanks and flow measurement.

3. Local Parameter Setting (LPS): Built-in high-contrast display enables on-site configuration, verification and      diagnosis without the need for a handheld device. Yokogawa Electric Corporation.

4. Remote Operation and Maintenance: Realizes remote monitoring, parameter modification and fault diagnosis via      HART/BRAIN protocols to improve operation and maintenance efficiency.

Typical Applications

1. Oil & Gas: Wellhead pressure monitoring, pipeline pressure control, tank liquid level measurement.

2. Chemical & Pharmaceutical Industry: Reactor pressure monitoring, distillation column pressure control, and      high-purity medium measurement.

3. Electric Power & Energy: Boiler steam pressure, turbine vacuum monitoring, gas turbine pressure control.

4. Water Treatment: High-pressure reverse osmosis pressure monitoring and pressure control in sewage treatment      processes.
