Suggested replacement Yokogawa officially recommends EJA110J as replacement family
Integrated functions Local parameter setting and self-diagnostics for CPU fail, hardware error, configuration error, and over-range condition
The suffix tail “819” is a configuration sequence defined by Yokogawa option code rules; exact local configuration details should be checked against the complete order record before procurement.

System Role

Control path

  • Provides high-accuracy differential pressure input for flow, level, and density loops in process automation systems.
  • Delivers standard loop signal and status data using 4~20 mA with digital metadata through digital communication stack.
  • Supports remote monitoring and setup through Yokogawa ecosystem interfaces, reducing on-site loop break intervention.

Protection and reliability behaviour

  • Built-in diagnostic logic monitors hardware and configuration abnormality states.
  • Long-term stability and overpressure performance are managed in the published specification model.
  • Suitable for installations demanding vibration, outdoor, and IP66/IP67 operation requirements in process environments.

Compatibility

  • Designed for Yokogawa BRAIN ecosystem, and compatible with HART-ready workflows for Yokogawa field service tooling.
  • Model architecture allows migration planning from legacy EJA110 units when mechanical envelope and loop wiring assumptions are preserved.
  • Lifecycle migration should focus on communication stack (BRAIN/HART option), output signal code, measurement span, and materials of wetted parts.

Applications

  • Flow measurement with differential pressure impulse elements (orifice, flow nozzles, etc.).
  • Liquid and gas level indication through DP-based level conversion.
  • Density or pressure ratio monitoring in utilities and process industries.
  • Retrofit projects where higher traceability and remote configuration are required before full replacement.

FAQ

What type of instrument is EJA110E-DHS4G-819?

It is an EJA110E differential pressure transmitter in Yokogawa's EJA-E series, configured for digital output with 4~20 mA loop compatibility.

Does it support digital communication and remote setting?

Yes. Yokogawa publishes that BRAIN/HART variants can be used with BRAIN terminal and FieldMate workflows for remote setting and monitoring.

What are the media and process applications?

Yokogawa positions the EJA110 series for liquid, gas, and steam measurement, and for flow, level, density, and pressure-oriented instrumentation loops.

Is the model still active?

The EJA110 family page indicates discontinuation on 2016-12-29 and points customers to EJA110J as recommended replacement.

Can I replace it directly with EJA110J?

It is officially listed as the replacement family, but direct swap should still be validated by loop interface (span, communication, housing, process connection, and approvals) before release.

What should we verify before approving a replacement order?

Confirm output protocol, process pressure class, measurement span, material compatibility, and any hazardous-area approvals against the target loop design.
