General Model EJA430

Specifications Gauge Pressure Transmitter

GS 01C22E01-00E [Style: S2]

The model EJA430 Gauge Pressure Transmitter can be

used to measure liquid, gas, or steam pressure. It outputs a
4 to 20 mA DC signal corresponding to the measured gauge
pressure.
The model EJA430 also features remote setup and monitor-
ing through communications with the model BT200/100
BRAIN TERMINAL, CENTUM CS/XL system etc.

The ‘夽’ marks indicate the most typical selection for each specification. Example: EJA430-DAS5A-92NA/䊐
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of
SUS316 material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.

*1: Refer to GS 01C22T01-00E for HART Protocol version.

ASTM grade 316L.
*3: Indicates diaphragm and other capsule wetted parts material.
*4: Indicates high pressure side cover flange and process connector material. Material of low pressure side cover flange (open to
atmosphere) is JIS SCS14A.
*5: If necessary, specify Mounting bracket code C, D or K.
*6: If necessary, specify Mounting bracket code A, B or J.
*7: Refer to GS 01C22T02-00E for Fieldbus communication.

*9: Indicated material is equivalent to ASTM M35-2.
*10: Not applicable for Output signal code F.
*11: 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.
