Product Details

The high performance absolute and gauge pressure transmitter EJA510E and EJA530E feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. EJA510E and EJA530E output 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 selfdiagnostics. 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.


Ambient Temperature Effects per 28°C (50°F) Change 

±(0.15% of Span + 0.15% of URL) for A, B and C capsule. ±(0.15% of Span + 0.15% of 50 MPa) for D capsule. 

Stability (All normal operating condition) 

EJA530E: ±0.1% of URL for 10 years 

EJA510E: ±0.2% of URL for 10 years 

Power Supply Effects 

±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 0.21 kPa (0.84 inH2O) which can be corrected by the zero adjustment. 


Response Time (All capsules) 

90 ms When software damping is set to zero and including dead time of 45 ms (nominal) 


FUNCTIONAL SPECIFICATIONS 

Output  

For 4 to 20 mA HART / BRAIN (Output signal code D and J) 

Two wire 4 to 20 mA DC output with digital communications, linear or square root programmable. 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 (Output signal code D and J) 

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, optional) 

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 Settings.” 


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 

A, B and C capsule: 30 MPa D capsule: 132 MPa 


Self Diagnostics 

CPU failure, hardware failure, configuration error, process alarm for pressure or capsule temperature. User-configurable process high/low alarm for pressure is also available 


Signal Characterizer (Output signal code D, J and Q) 

User-configurable 10-segment signal characterizer for 4 to 20 mA output. 

SIL Certification 

EJA-E series transmitters except Fieldbus, PROFIBUS PA and 1-5V DC with HART(Low Power) communication types are certified in compliance with the following standards; IEC 61508: 2010; Part1 to Part 7 Functional Safety of Electrical/electronic/ programmable electronic related systems; SIL 2 capability for single transmitter use, SIL 3 capability for dual transmitter use. 


NORMAL OPERATING CONDITION (Optional features or approval codes may affect limits.) 

Ambient Temperature Limits 

?40 to 85°C (?40 to 185°F) ?30 to 80°C (?22 to 176°F) with LCD display Process Temperature Limits 

?40 to 120°C (?40 to 248°F)


Supply Voltage

For 4 to 20 mA HART / BRAIN (Output signal code D and J) 10.5 to 42 V DC for general use and flameproof type. 10.5 to 32 V DC for lightning protector  (option code A). 10.5 to 30 V DC for intrinsically safe, type n, nonincendive or non-sparking type.
