What the EJA110E is, in plain terms
Per Yokogawa’s published data, the EJA110E measures differential pressure as its main variable and can also report static pressure. It is used for liquid, gas and steam flow (with an orifice plate or similar primary element), liquid level, density and pressure.
| Item | Published data |
|---|---|
| Series | EJA-E, DPharp sensor technology, traditional-mount body |
| Reference accuracy | ±0.055% of span for differential pressure (0.04% option) |
| Rangeability | 100:1 |
| Response time | 90 ms (differential pressure) |
| Capsule codes | F, M, H and V, each covering a different span range |
| Safety rating | Yokogawa lists SIL 2 for a single transmitter and SIL 3 for a dual-transmitter configuration |
| Communication | 4-20 mA output with BRAIN, HART, FOUNDATION Fieldbus or PROFIBUS PA, depending on the output code in the model string |
Figures are Yokogawa’s published data for a standard unit and vary with the exact model code. Check your own nameplate and the Yokogawa general specification for your suffix codes.
EJA110E parts people ask for
This list follows typical failure patterns. Your fault may differ, so send the symptom with the model code.
| Part | Why it is usually needed | What we do |
|---|---|---|
| Amplifier (CPU) assembly | Output stuck or erratic, no HART or BRAIN communication, blank display | Supply, or board-level repair where circuits and parts allow |
| Capsule (sensor) assembly | Reading drift or no response after overpressure, corrosion or process-side damage | Supply of a matching capsule, or advice to replace the transmitter |
| Integral indicator | Cracked or blank display | Supply |
| Cover, O-ring and terminal block | Moisture ingress, damaged cover threads, corroded terminals | Supply |
| Process flange gasket and bolts | Leakage at the cover flange after service | Supply on request |
Read the full model code before you order
Two EJA110E units can differ in capsule range, wetted-part material, output signal and approvals. A capsule or amplifier that fits one unit may not suit another. The nameplate carries what we need.
- Full MODEL line, for example EJA110E followed by the suffix and option codes, including anything after the slash
- Capsule code (F, M, H or V) and the calibrated range
- Output signal and communication type
- STYLE code and serial number
- A photo of the nameplate and the symptom in one line
Check the loop first, then the transmitter
Many “transmitter faults” are in the impulse lines or the wiring. These checks take a few minutes with your plant’s own procedure and save a wrong purchase.
| Symptom | Check first | Likely part if the transmitter is at fault |
|---|---|---|
| Reading stuck or noisy | Blocked or leaking impulse line, manifold valve position, air or condensate in the line | Capsule or amplifier |
| No HART or BRAIN communication | Loop resistance, supply voltage at the terminals, wiring polarity | Amplifier assembly |
| Blank display, loop current present | Indicator connector and cover contact | Integral indicator |
| Zero shift after overpressure or cleaning | Re-trim zero with the transmitter isolated; compare with a reference | Capsule assembly |
| Water in the terminal compartment | Cover seal, conduit entry and cable gland | Terminal block, O-ring, possibly the amplifier |
Follow your site permit and isolation procedure and Yokogawa’s instruction manual when working on a live loop.
Supply, repair or replace
Supply
New surplus, refurbished-and-tested or used parts, as the part allows. The condition is stated in the quote.
Repair
Amplifier boards are repaired at board level where circuits and parts allow. We confirm repairability from your photo before you ship, and test the unit before return.
Replace
If the capsule is damaged or the model is discontinued, we tell you plainly whether a matching part or a replacement transmitter is the practical route. See repair or replace advice.
Send the model code
Name, contact and the nameplate photo are enough to start.

Common questions
What is the Yokogawa EJA110E?
It is a standard traditional-mount differential pressure transmitter in Yokogawa’s EJA-E series. Plants use it for flow measurement with an orifice plate, for liquid level and for pressure. It reports differential pressure and can also report static pressure.
Do you supply EJA110E spare parts in India?
Yes. We source EJA110E amplifier assemblies, capsule assemblies, indicators, covers and terminal parts as new surplus, refurbished-and-tested or used stock. The condition is stated in the quote. Send the full model code and we confirm availability.
Can you repair an EJA110E amplifier board?
We repair amplifier boards at board level where circuits and parts allow, and confirm repairability from the nameplate and a photo before you ship. A damaged capsule usually means a replacement capsule or transmitter rather than a repair, and we tell you which is practical.
What should I send for a quote?
The full model line with suffix and option codes, the capsule code and range, the style and serial number, a photo of the nameplate, the symptom, the quantity and the delivery location. WhatsApp +91 97866 22233 works well.
Is an EJX110A the same as an EJA110E?
No. The EJX110A is a related model from the earlier EJX series. Parts are not always interchangeable between the two, so confirm with the full model code before ordering.
How do I choose between repairing and replacing the transmitter?
Repair usually makes sense when the amplifier or indicator has failed and the capsule is healthy. Replacement is usually the better route when the capsule is damaged, the unit is badly corroded or the model is discontinued. Send the fault and nameplate and we give an honest recommendation.
Are you a Yokogawa authorised dealer or service centre?
No. Star Automations is an independent multi-brand repair and supply company and is not an OEM service centre. For a new transmitter under OEM warranty, contact Yokogawa or its channel partners.
Is a repaired transmitter suitable for a safety-instrumented loop?
Treat a repaired or non-OEM transmitter as unsuitable for a certified SIL function unless your functional-safety assessment accepts it. The safety rating applies to the Yokogawa-certified configuration. For safety loops, ask your safety engineer before reusing any repaired unit.
