Yokogawa Electric announces the release of the OpreX™ Pressure Transmitter EJX S Series as the successor to its core EJX A lineup of plant field instruments. Building on the proven silicon resonant sensor technology the EJX S Series offers enhancements in accuracy, long-term stability, and durability that ensure stable plant operations and improve maintenance efficiency.
Improved accuracy and stability
The accuracy of the transmitters is in a range of ±0.025%, with optional specification code /HAC. The series offers a high long-term stability (±0.1% per 20 years) and rangeability of up to 400:1. HART and PROFINET communication protocols are supported. With an IP68 dustproof and waterproof rating, compliance with SIL2 requirements, and enhanced noise immunity, the EJX S Series is even more reliable and robust. In addition, a new color backlit graphic display significantly improves visibility of process variables and device status information.
Streamlined specifications for reduced costs
Compliance with a variety of explosion-proof standards, support for dual power connections, and advanced diagnostic functions are all provided as standard features with the EJX S Series, allowing these devices to cover a wider range of applications and reducing the need for the ordering of products with specific model and suffix codes. Furthermore, a modular design allows parts replacement and maintenance work to be carried out easily and efficiently. Together, these characteristics help to improve maintenance efficiency and reduce inventory costs. In addition, the LCD color display supports NAMUR NE107-compliant alert indications, enabling intuitive recognition of device status even from a distance. This facilitates faster on-site inspections.
The OpreX Pressure Transmitter EJX S Series pressure transmitters were designed to reduce environmental impact over the entire product lifecycle. CO2 emissions have been significantly reduced during the production process, helping customers reduce their Scope 3 emissions. A modular design allows for easy disassembly and disposal contributes to the optimization of customers' maintenance parts and inventory, as well as a reduction in environmental impact after use.
