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 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. Ultra-long Stability: Only ±0.2% URL drift over 15 years, greatly reducing calibration frequency and lowering maintenance costs Ultra-fast Response: 90ms rapid response, suitable for scenarios with dynamic pressure changes 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 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 DPharp Digital Sensing: Outputs digital signals directly without analog-to-digital conversion, minimizing errors and enhancing measurement reliability. 10-segment signal curve characterization: Supports nonlinear compensation and adapts to complex application scenarios such as tanks and flow measurement. 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. Remote Operation and Maintenance: Realizes remote monitoring, parameter modification and fault diagnosis via HART/BRAIN protocols to improve operation and maintenance efficiency. Typical Applications Oil & Gas: Wellhead pressure monitoring, pipeline pressure control, tank liquid level measurement. Chemical & Pharmaceutical Industry: Reactor pressure monitoring, distillation column pressure control, and high-purity medium measurement. Electric Power & Energy: Boiler steam pressure, turbine vacuum monitoring, gas turbine pressure control. Water Treatment: High-pressure reverse osmosis pressure monitoring and pressure control in sewage treatment processes. For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
