OverviewThe EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family. Released in 2012, it combines the ruggedness and success of the work-horse EJA-E series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.The EJA430E is a traditional-mount gauge pressure transmitter in the series.EJA430E features include:0.055% Accuracy (0.04% Accuracy optional)0.1% Stability per 10 years90 ms Response TimeExida and TUV SIL 2/3 CertifiedLocal Parameter Setting (LPS)SpecificationsMeasurement TypesPrimary Variable: Gauge PressureReference AccuracyPrimary Variable: ±0.055% of Span±0.04% of Span (with /HAC option)Stability (All Normal Operating Conditions)Primary Variable: ±0.1% of URL per 7 yearsResponse TimePrimary Variable: 90msRangeabilityPrimary Variable: 100:1Burst Pressure (Absolute)EJA510E:Wetted Parts code S: 10,000 psiAll other Wetted Parts: 6,800 psiSpecification ConformanceEJA-E Series: ±3sModel and Suffix Codes Model EJA430E Gauge pressure transmitter Output signal -F Digital communication (FOUNDATION Fieldbus protocol, refer to GS 01C31T02-01EN) Measurement span (capsule) A 0.03 to 3.5 MPa (4.3 to 500 psi) Wetted parts material(1) S# Cover flange and process connector: ASTM CF-8M(2)Capsule: Hastelloy C-276(3) (Diaphragm), F316L SST, 316L SST (Others)Capsule gasket: Teflon-coated 316L SSTVent/Drain plug: 316 SST Process connections *5 without process connector (1/4 NPT female on the cover flanges) Bolts and nuts material G 316L SST Installation *-9 Horizontal piping and left side high pressure Amplifier housing 1 Cast aluminum alloy Electrical connection 9 M20 female, two electrical connections and a blind plug(4) Integral indicator D Digital indicator(5) Mounting bracket *B 304 SST 2-inch pipe mounting, flat type (for horizontal piping) /FS15 Calibration Unit(6) /D3 bar calibration (bar unit) Material Certificate(7) /M01 Cover flange(8) The “*” marks indicate the most typical selection for each specification.The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR0175/ISO 15156. Please refer to the latest standards for details. Selected materials also conform to NACE MR0103. Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm and the fill fluid can contaminate the user’s process fluids.Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high-temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the wetted parts material. Cast version of 316 SST. Equivalent to SCS14A.Material of a blind plug is aluminum alloy or 304 SST. Not applicable for output signal code G.The unit of MWP (Max. working pressure) on the name plate of a housing is the same unit as specified by option codes D1, D3, and D4.Material traceability certification, per EN 10204 3.1B.Applicable for process connections code 0 and 5.
