Product description

Yokogawa  EJX930A  is a high-performance multivariable transmitter in the EJX-a series, which integrates a proprietary DPharp  monocrystalline silicon resonant sensor. It simultaneously measures differential pressure (DP), static pressure (SP),  and process temperature, and then dynamically calculates the fully compensated mass flow rates of liquids, gases, and  vapors for Yokogawa Electric Corporation. It is very suitable for high static pressure applications, combining multi  parameter measurement and flow calculation in one device, reducing system cost and complexity.

Core Features

• Dual Configuration Options:

  1.Mass Flow Version: Computes mass flow with ±1.0% accuracy; supports orifice, nozzle, Venturi (plus Pitot/cone      meters for HART7)Yokogawa Electric Corporation

  2.Multi-Sensing Version: ±0.04% DP accuracy, ±0.1% SP accuracy, ±0.9°F external temp accuracy.

• High Working Pressure: 4,500 psi (310 bar) MWP, suitable for oil/gas and petrochemical high-pressure processes.

• Dynamic Compensation: Real-time DP/SP/temp data compensates flow for density/temp/pressure changes, ensuring      accuracy.

• Long-Term Stability: ±0.1% drift per 15 years, extending calibration intervals and lowering maintenance.

• Safety Certified: TUV SIL2/SIL3 certified for safety-critical systems

• Multi-Protocol Communication: Supports HART5/7, FOUNDATION Fieldbus, RS485 Modbus for seamless integration.

• Advanced Diagnostics: Detects impulse line blockages, sensor faults, and process abnormalitiesYokogawa Electric      Corporation

• Flow Totalizer & Pulse Output: Mass flow totalizer (±1.0% accuracy) with pulse/contact output for remote      monitoring
