Yokogawa EJX110A-JLH4G-919EB/KU22 EJX-A Series Differential Pressure Transmitter 4-20mA
Yokogawa EJX110A-JLH4G-919EB/KU22 Differential Pressure Transmitter | 0.04 % Accuracy, SIL2, HART 7, –40 °C to +85 °C
Product Overview
The Yokogawa EJX110A-JLH4G-919EB/KU22 is a high-performance differential pressure transmitter that combines the proven DPharp® resonant silicon sensor with advanced digital signal processing. Engineered for critical flow, level and pressure applications, this model delivers ±0.04 % reference accuracy, 100 ms response and 15-year stability, cutting lifetime ownership costs in oil & gas, chemical, power and pharmaceutical plants.
Key Features & Benefits
• Ultra-High Accuracy – ±0.04 % of span; ±0.1 % per 10-year stability minimizes calibration downtime.
• SIL2 / SIL3 Capable – IEC 61508 certified for safety-instrumented systems; FMEDA data supplied.
• Multi-Variable Output – Simultaneous differential pressure, static pressure and process temperature via HART 7, FOUNDATION Fieldbus or PROFIBUS-PA.
• Advanced Diagnostics – Plugged-impulse-line detection, heat-map trending and spectral signal analysis predict failures before they happen.
• Rugged Construction – IP66/IP67, NEMA 4X, marine-grade polyurethane coating; operates –40 °C to +85 °C (-40 °F to 185 °F).
• Universal Mounting – ½-inch NPT, DIN 19213 or coplanar flanges; integral rotatable LCD or remote indicator option.
