Key Benefits and Advantages
Exceptional High Static Pressure Capability: The EJA130E is built to excel where standard transmitters reach their limits. Featuring a robust design that supports a Maximum Working Pressure (MWP) of 4,500 psi, it provides the necessary strength and safety margin for high-pressure industrial systems, such as deep-water oil production and high-pressure chemical processes.
Proven Precision and Accuracy: This transmitter maintains a standard reference accuracy of ± 0.055% of span. This high level of precision ensures that your control system receives consistent, high-quality data, which is essential for optimizing flow calculations and maintaining tight process control in complex architectures.
Long-Term Field Reliability: Stability is a cornerstone of the EJA-E series, and the EJA130E offers a stability rating of ± 0.1% per 10 years. This long-term durability reduces the need for frequent manual calibrations, lowering maintenance costs and ensuring the integrity of your measurements over a decade of operation.
SIL 2/3 Certified Safety: For processes where safety is paramount, the EJA130E is Exida and TUV SIL 2/3 certified. This ensures the transmitter can be integrated into Safety Instrumented Systems (SIS) with full compliance to global safety standards, protecting both personnel and plant assets.
Versatile Communication and Power Options: To support diverse industrial networks, the EJA130E is available with multiple protocols including HART 5/7, FOUNDATION Fieldbus, PROFIBUS PA, and BRAIN. Additionally, a 1 to 5 VDC HART 7 (Low Power) version is available for remote or solar-powered installations.
Streamlined Field Configuration: The Local Parameter Setting (LPS) feature allows technicians to configure and adjust basic transmitter settings directly in the field. This local interface eliminates the need for external handheld tools during routine setup, speeding up commissioning and reducing downtime.
