Product Description EJX430A is a high-performance gauge pressure transmitter from Yokogawa EJX-A series, equipped with Yokogawa's exclusive DPharp monocrystalline silicon resonant sensing technology. It is designed for harsh industrial conditions such as petroleum, chemical, power, natural gas, and water treatment, and accurately measures gauge pressure parameters of gases, liquids, and steam. Adopting a fully digital sensing architecture, bidding farewell to traditional analog signal errors, it has advantages such as ultra-high precision, long-term zero drift, wide range ratio, and intelligent self diagnosis. It supports multiple industrial communication protocols and is the mainstream high-end model for industrial process pressure measurement and control. Core Advantage Ultra high measurement accuracy: The benchmark accuracy can reach ± 0.04%, and the high-precision version can reach ± 0.025%, meeting the requirements of fine process control. Long term stability: 15 years of long-term drift with only ± 0.1% URL, no need for frequent on-site calibration, significantly reducing maintenance and labor costs in the later stage Ultra wide range ratio: maximum 200:1 range ratio, one transmitter can cover multiple operating ranges, reducing stocking models and lowering procurement inventory costs. Quick response capability: With a response time of only 90ms, it is suitable for real-time measurement and control scenarios with large pressure fluctuations and dynamic working conditions. Intelligent diagnosis and on-site operation: Equipped with a built-in LCD display panel, supporting on-site parameter setting, configuration, verification, and fault diagnosis; Remote debugging, monitoring, and warning of faults such as pressure pipe blockage and temperature anomalies can be achieved through protocols such as HART, reducing unplanned shutdowns. High safety explosion-proof level: with SIL2/3 functional safety certification, supporting explosion-proof and intrinsic safety explosion-proof, suitable for use in hazardous explosion-proof areas such as chemical and oil and gas industries. Applicable Industry Scenarios Oil and gas: wellhead pressure, oil and gas pipelines, station pressure monitoring. Chemical and pharmaceutical industry: reaction kettle, distillation tower, process pipeline pressure control. Power Industry: Pressure measurement of steam/medium in boilers, steam turbines and auxiliary machinery systems. Water treatment&environmental protection: high-pressure reverse osmosis, pump station, sewage treatment process pressure monitoring. Pressure measurement and control for industrial processes such as metallurgy, papermaking and building materials For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
