Yokogawa EJA438E Diaphragm Sealed Pressure Transmitter

About this product

Product Description The EJA438E diaphragm sealed pressure transmitter adopts single crystal silicon resonant sensor technology, which is suitable for measuring the pressure and liquid level of high and low temperature, high vacuum, high viscosity, and easily crystallized media. It has functions such as fast response, remote setting, and self diagnosis. Core Advantages Remote Diaphragm Seal Design：Built-in remote diaphragm structure isolates high-viscosity, easily crystallizable, particle-containing and strongly corrosive media, prevents impulse line blockage, and avoids damage to the transmitter caused by media entering its interior. Excellent high temperature resistance：It can isolate heat from high-temperature media, adapt to high-temperature process working conditions, protect the transmitter body, and extend its service life. Ultra-high measurement accuracy + ultra-stable performance：Accuracy up to ±0.1%FS with a turndown ratio as high as 115:1; long-term stability of ±0.2% over 10 years, requiring almost no frequent calibration and saving maintenance costs. Original DPharp Single-Crystal Silicon Resonant Sensing Technology：Digital sensing, low temperature drift, and strong anti-interference capability. It delivers more stable measurement and lower failure rate compared with ordinary diffused silicon transmitters. Multiple material options available with excellent corrosion resistance：Optional wetted diaphragm materials include 316L, Hastelloy, Monel and Tantalum, suitable for working conditions with strong acid, strong alkali and severe chemical corrosion. Multi-communication Protocol Compatibility：Supports HART, BRAIN, FF and PROFIBUS PA protocols, compatible with major DCS/PLC systems for seamless installation and integration. On-site tool-free configuration：Comes with a built-in key display screen; range adjustment and parameter setting can be done on-site without a handheld operator, enabling simple and time-saving commissioning. High Safety Level Certification：It features SIL2/SIL3 functional safety certification and can be applied to SIS safety interlock systems in chemical, oil and gas industries, ensuring reliable operation in high-risk working conditions. Improve the self-diagnosis function：Built-in intelligent self-diagnosis, automatic fault early warning, hidden danger inspection in advance, and reduction of production line downtime losses. High protection grade and strong environmental adaptability：IP66/IP67 dustproof and waterproof, with an optional explosion-proof version available. It can operate stably in outdoor, field and hazardous areas. Typical Application Scenarios Petrochemical Industry Chemical Engineering and Pharmaceuticals Food and Beverage Electric Energy Environmental Protection and Water Treatment Metallurgy and Building Materials For quotation, send the complete order code, quantity and operating conditions.
