Yokogawa EJX110A-EMS4G-919EB/KU21 High Performance Differential Pressure Transmitter 4-20mA
Overview
The Yokogawa EJX110A-EMS4G-919EB/KU21 is a premium-performance differential pressure (DP) transmitter built on the proven DPharp® silicon resonant sensor platform. Delivering ±0.04 % reference accuracy, 100 ms response time and multi-sensing capabilities, this model excels in flow, level and pressure applications across oil & gas, chemical, power and pharmaceutical industries.
Key Features
• Best-in-Class Accuracy – ±0.04 % of span with ±0.1 % per 10-year stability reduces calibration cost.
• Multi-Variable Output – Simultaneous DP, static pressure (SP) and process temperature via HART 7 / FOUNDATION Fieldbus.
• SIL2 Certified – IEC 61508-compliant for safety loops; FMEDA data available for SIL verification.
• Rugged Design – 15-year MTBF; IP66/IP67 and NEMA 4X enclosure withstands –40 °C to +85 °C.
• Advanced Diagnostics – Plugged-impulse-line detection, heat-map trending and optional spectral signal analysis.
• Universal Mounting – ½-inch NPT, DIN 19213 or coplanar flanges; integral or remote LCD display.
