Product Description The EJX438A 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 Technology Ultra-high Accuracy: ±0.15% FS, Excellent Long-term Stability Yokogawa Electric Corporation. Fast Response: 200ms response time, suitable for dynamic working conditions. Safety Certification: SIL2 (Single Unit) / SIL3 (Redundancy), Exida & TUV Certified, Compliant with IEC 61508, Yokogawa Electric Corporation. Digital Sensing: DPharp Silicon Resonant Technology, direct digital output, anti-interference and drift-free. Remote Seal: Isolates high-temperature / corrosive / viscous media, anti-clogging and maintenance-free. Intelligent Compensation: Automatic density compensation for capillary filling liquid, minimizing the impact of temperature/static pressure Yokogawa Electric Corporation. Multi-protocol Communication: Supports HART 5/7, BRAIN, FF, PROFIBUS PA, compatible with mainstream systems. Local Parameter Setting (LPS): No handheld communicator required; parameter configuration can be completed via local buttons. Application Scenarios Petrochemical Industry: Reactors, Distillation Towers, Pressure / Liquid Level Measurement for High-temperature / Corrosive Media. Oil and Gas Industry: Gauge Pressure and Liquid Level Monitoring of Wellheads, Pipelines and Storage Tanks. Electric Power Energy: Pressure measurement for boilers, steam turbines, and high-temperature steam. Pharmaceutical / Food Industry: Level / pressure measurement for aseptic processes and high-viscosity media (syrup, fermentation broth). Water Treatment / Environmental Protection: Pressure and liquid level monitoring for sewage, sludge, and corrosive liquids. For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
