Product Description

The  EJA310E  high-performance absolute pressure transmitter adopts single crystal silicon resonant sensing technology, which is  suitable for measuring the pressure of liquids, gases, or vapors. EJA310E converts measured pressure into 4-20mA DC  current signal output, with functions such as fast response, remote setting, and self diagnosis.

Core Advantages

1. Ultra-high measurement accuracy：Standard accuracy reaches ±0.1%FS with a turndown ratio as high as 115:1. One      unit can replace multiple transmitters of different ranges, making inventory preparation and model selection much      more hassle-free.

2. 10-Year Ultra-long Stability：Long-term drift over 10 years is only ±0.2%, eliminating the need for frequent      calibration and significantly reducing subsequent maintenance, labor and downtime costs.

3. Original DPharp Single Crystal Silicon Resonant Sensing Technology：Pure digital sensing, low temperature drift,      and strong electromagnetic interference resistance. It is more durable and delivers more stable measurement than      ordinary diffused silicon transmitters.

4. Fast response speed：Fast response in only 90ms, ideal for precise measurement and control under dynamic pressure,      vacuum and transient working conditions.

5. Strong pressure resistance and overload capacity：Maximum working pressure: 3600 psia, burst pressure up to 10000      psi. It features impact resistance, high durability and strong adaptability to various working conditions.

6. High Safety Level Certification：It has obtained SIL2/SIL3 functional safety certification and complies with      IEC61508 standard, applicable to SIS safety interlock systems for reliable use in high-risk working conditions.

7. Multi-communication Protocol Compatibility：Supports HART5/7, FF, PROFIBUS PA, BRAIN and other protocols,      compatible with various domestic and foreign DCS and PLC systems with excellent compatibility.

8. On-site tool-free configuration：Built-in keys plus LCD display allows on-site range modification and parameter      setting without a handheld calibrator, enabling efficient and time-saving commissioning.

9. Comprehensive Self-Diagnosis Function：Over 40 self-diagnosis items plus patented reverse verification, with      automatic fault alarm, early hidden danger prediction, and reduced downtime risk.

10. Multiple material options, wide adaptability with corrosion resistance：Wetted parts material options include      316L, Hastelloy, Monel and Tantalum, suitable for measurement of chemical, corrosive and high-purity media.
