YOKOGAWA Pressure Transmitter EJA430E-JAS3J-712EC/Z

The high performance gauge pressure transmitter EJA430E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure. The EJA430E outputs a 4 to 20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup and monitoring via BRAIN or HART communications and self-diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available. All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.

Reference Accuracy of Calibrated Span (includes the effects of terminal-based linearity, hysteresis, and repeatability)

Stability (All normal operating condition) 

±0.1% of URL per 10 years 

Power Supply Effects(Output signal code D and J) 

±0.005 % per Volt (from 21.6 to 32 V DC, 350Ω) 

Vibration Effects 

Amplifier housing code 1 and 3: 

Less than 0.1% of URL when tested per the requirements of IEC60770-1 field or pipeline with high vibration level (10-60 Hz, 0.21 mm displacement/60-2000 Hz 3 g) 

Amplifier housing code 2: 

Less than ±0.1% of URL when tested per the requirements of IEC60770-1 field with general application or pipeline with low vibration level (10-60 Hz 0.15mm displacement /60-500 Hz 2g) 

Mounting Position Effects 

Rotation in diaphragm plane has no effect. Tilting up to 90 degree will cause zero shift up to 0.4 kPa (1.6 inH2O) which can be corrected by the zero adjustment. 

Response Time (All capsules)

90 ms 150 ms for H capsule with Wetted Parts Material code H, M, T, A, D, B and W. When software damping is set to zero and including dead time of 45 ms (nominal)
