YOKOGAWA EJA430E liquid gas steam differential pressure transmitter

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.PERFORMANCE SPECIFICATIONS Zero-based calibrated span, linear output, wetted parts material code ‘S’ and silicone oil, unless otherwise mentioned. For Fieldbus and PROFIBUS PA communication types, use calibrated range instead of span in the following specifications. Specification Conformance EJA-E series ensures specification conformance to at least ±3σ. 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.

BRAIN or HART FSK protocol are superimposed on the 4 to 20 mA signal. Output range: 3.6 mA to 21.6 mA Output limits conforming to NAMUR NE43 can be pre-set by option code C2 or C3. For 1 to 5 V HART (Output signal code Q) Three or four wire low power 1 to 5 V DC output with HART, linear or square root programmable. HART protocol are superimposed on the 1 to 5 V DC signal. Output range: 0.9 V to 5.4 V DC Failure Alarm For 4 to 20 mA HART / BRAIN (Output signal code D and J) Output status at CPU failure and hardware error; Up-scale: 110%, 21.6 mA DC or more (standard) Down-scale: ?5%, 3.2 mA DC or less For 1 to 5 V HART (Output signal code Q) Analog output status at CPU failure and hardware error; Up-scale: 110%, 5.4 V DC or more (standard) Down-scale: ?5%, 0.8 V DC or less Damping Time Constant (1st order) Amplifier’s damping time constant is adjustable from 0.00 to 100.00 s by software and added to response time. Note: For BRAIN protocol type, when the software damping is set to less than 0.5 s, communication may occasionally be unavailble during the operation, especially while output changes dynamically. The default setting of damping ensures stable communication. Update Period Pressure: 45 ms Zero Adjustment Limits Zero can be fully elevated or suppressed, within the lower and upper range limits of the capsule. External Zero Adjustment External zero is continuously adjustable with 0.01% incremental resolution of span. Re-range can be done locally using the digital indicator with rangesetting switch. Integral Indicator (LCD display) 5-digit numerical display, 6-digit unit display and bar graph. The indicator is configurable to display one or up to three of the following variables periodically.; pressure in %, scaled pressure, measured pressure. See also “Factory Setting”. Local Parameter Setting (Output signal code D, J and Q) Parameter configuration by the external zero adjustment screw and push button (Integral indicator code E) offers easy and quick setup for parameters of Tag number, Unit, LRV, URV, Damping, Output mode (linear/square root), Display out 1, and Re-range by applying actual pressure (LRV/URV).Burst Pressure Limits 69 MPa (10,000 psi) for wetted parts material S and L. 47 MPa (6,800 psi) for wetted parts material other than S and L.
