Yokogawa EJA530E
In-Line Mount Gauge Pressure Transmitter
The Yokogawa EJA530E is an in-line mount gauge pressure transmitter using a DPharp single-crystal silicon resonant sensor. It is designed to measure liquid, gas or steam pressure in industrial process installations. Confirm the complete model code and ordered configuration when sourcing a replacement.
Application & Failure Scenarios
Relevant process industries include chemical processing, oil and gas, power, and water and wastewater treatment.
| Unstable reading | Check the process condition, instrument setup and measurement loop. |
| Alarm or signal loss | Verify power, wiring, communication type and diagnostic status as applicable. |
| Replacement after failure | Match the range, process connection, output and material configuration. |
Unreliable pressure feedback may reduce process control quality or contribute to an unplanned shutdown where the measurement is operationally critical.
Technical Specifications
Published family specifications. Exact values depend on the selected model code and configuration.

| Long-term stability | ±0.1% of URL per 10 years under specified normal operating conditions |
| Response time | 90 ms |
| Rangeability | Capsule A: 20:1; capsules B, C and D: 100:1 |
| Process media | Liquid, gas or steam, subject to configuration and material compatibility |
| Mounting | In-line mount |
| Output / communication | 4–20 mA with BRAIN/HART; FOUNDATION Fieldbus; PROFIBUS PA; low-power 1–5 V DC with HART (model-dependent) |
Span codes & communication options
Published span values for the EJA530E family:
| Capsule | Specified span |
|---|---|
| A | 10–200 kPa (1.45–29 psi) |
| B | 0.1–2 MPa (14.5–290 psi) |
| C | 0.5–10 MPa (72.5–1450 psi) |
| D | 5–50 MPa (720–7200 psi) |
These are family span specifications, not confirmation of the range configured on a particular unit. Output options documented for the family include 4–20 mA DC with BRAIN or HART, FOUNDATION Fieldbus, PROFIBUS PA, and low-power 1–5 V DC with HART. Verify the exact variant before replacement.
Replacement Compatibility
Match the complete model code, pressure range, output protocol, process connection, wetted materials and required approvals with the installed instrument. A matching base model alone does not establish full interchangeability.
Delivery & Warranty
Testing scope, stock, lead time, return authorization and warranty remedies are confirmed by quotation. Warranty excludes damage caused by improper installation, misuse or unauthorized modification.
