Specifications
Category Specification
Model Code EJA430A-EA
Type Differential Pressure (DP) Transmitter
Measuring Range Range Code 4 (URL = 100 kPa): Adjustable from 0.5 - 3.5 kPa to 10 - 100 kPa (2.0 - 14 inH₂O to 40 - 400 inH₂O).
Note: The "A" in the suffix often denotes a 100 kPa (400 inH₂O) URL. The exact range should be confirmed on the product tag.
Process Connection 1/4 NPT female on both the high and low-pressure sides.
Mounting 2-inch pipe mounting (requires a separate mounting bracket).
Wetted Parts SUS316L Stainless Steel (Diaphragm, O-rings)
Accuracy ±0.2% of URL (Standard for EJA-A series at that time)
Output Signal 4 to 20 mA DC, two-wire system.
Power Supply 10.5 to 42 V DC (Standard)
12 to 30 V DC (Typical operating range)
Sensor Technology Single-Crystal Silicon Resonant Sensor
Turn-Down Ratio 15:1
Response Time 0.15 s (150 ms), adjustable to 2.4 s or 6.4 s.
Stability ±0.1% of URL per 10 years (typical)
Process Temperature -40 to 120 °C (-40 to 248 °F)
Ambient Temperature -40 to 85 °C (-40 to 185 °F)
Pressure Limit Working Pressure (Static Pressure): 16 MPa (2320 psi) for the low-pressure side flange.
