EJA110E Differential Pressure Transmitter
Part number EJA110E-JMS4G-912DB
DPharp silicon-resonant DP transmitter, ±0.055 % accuracy, 4–20 mA HART 7, for DP flow, level and filter monitoring, SIL2/3 capable.

Overview
The EJA110E is the differential-pressure member of Yokogawa's EJA-E series, built on the DPharp silicon-resonant sensor that measures pressure as a frequency rather than an analog voltage — the reason these transmitters hold calibration for years without drift. Standard accuracy is ±0.055 % of span with a 100:1 turndown, and the multi-sensing design delivers static pressure alongside DP on the same loop. It is used for orifice-plate flow, differential level in closed tanks and filter differential monitoring. EJA110E is an ordering family: the suffix code specifies capsule (L, M, H, V), process connection, output and approvals, and we configure it with you before quoting.
Key features
- DPharp silicon-resonant sensor: digital output from the sensing element, long-term stability ±0.1 % of URL per 10 years
- Reference accuracy ±0.055 % of span (±0.04 % optional), 100:1 turndown
- Static pressure read-out from the same transmitter, no second loop
- 4–20 mA HART 7, FOUNDATION Fieldbus or PROFIBUS PA; local LCD with external zero adjustment
- SIL2 (SIL3 in redundancy) per IEC 61508; ATEX, IECEx, FM, CSA, NEPSI, TIIS approvals
Typical applications
- Orifice, Venturi and Annubar DP flow in utilities and process lines
- Level in pressurized vessels and boiler drums
- Filter and strainer differential monitoring
- Safety instrumented functions in SIL2 loops

Frequently asked questions
What is the difference between EJA110E and EJX110A?
EJX is the premium line: higher base accuracy (±0.04 %), faster 90 ms response and extended multivariable features. EJA-E covers most DP flow and level loops at a lower price with the same DPharp sensor. We quote both when the application does not clearly require EJX.
Can the EJA110E replace an old EJA110A one-for-one?
Yes. Process connections, mounting and terminal layout are compatible, and the suffix code converts almost directly. Send us the old model code and we return the current equivalent.
Is the EJA110E available from stock, and what is the lead time?
Standard capsule and approval combinations are typically 3–6 weeks from the factory; some configurations are held in regional stock. We confirm the exact lead time with the quotation.
