More Information

Overview Manuals Applications Efficiency Compatibility Diagnostics

Features:

  • The legacy HAC high-accuracy direct-mount configuration uses the 0.5 to 10 MPa (72.5 to 1450 psi) capsule, direct-mount pressure connection and 1/2 NPT female, two entries without blind plug.
  • The legacy HAC high-accuracy direct-mount configuration provides 4–20 mA DC with digital communication through HART protocol, with no integral indicator.
  • The legacy HAC high-accuracy direct-mount configuration combines 1/2 NPT female process connection, SUS316L process connector with Hastelloy C-276 diaphragm and No mounting bracket.
Use the full EJA530A-ECS4N-02NN/HAC code when matching the configuration defined by HAC high-accuracy selection with C capsule and no local display.

It converts gauge pressure into a control-system signal and supports configuration or diagnostic access through HART protocol.

The replacement review must resolve high-accuracy calibration, capsule or HART device generation before the equipment is returned to service.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • The legacy HAC high-accuracy direct-mount configuration measures direct gauge pressure in liquid, gas or steam service through the selected process connection.
  • The legacy HAC high-accuracy direct-mount configuration supports legacy HART control loops that require the documented high-accuracy transmitter option.
  • The legacy HAC high-accuracy direct-mount configuration provides process-pressure feedback for control or monitoring where the existing EJA-A configuration is retained.
  • The two-wire 4–20 mA DC with digital communication loop combines power and measurement transmission while retaining HART protocol parameter access.
  • In the documented efficiency context, remote setup and self-diagnostics reduce unnecessary enclosure opening during routine service activities.
  • Because no integral indicator is fitted, local verification requires the connected loop or a compatible handheld tool.
  • The receiving system must support HART protocol over the selected 4–20 mA DC with digital communication output and the applicable device revision.
  • When reviewing compatibility, mechanical replacement requires the same 1/2 NPT female process connection, pressure capsule and high-pressure-side orientation.
  • Local-access and mounting requirements must allow for a configuration without an integral indicator or mounting bracket.
  • When reviewing diagnostics, self-diagnostics supervise CPU, hardware, configuration and measurement-overrange conditions during operation.
  • Diagnostic status is available through HART protocol and must be mapped separately from the primary pressure value.
  • In the documented diagnostics context, a replacement check should verify capsule-temperature and process-alarm behavior for the selected 0.5 to 10 MPa (72.5 to 1450 psi) span.
Description
EJA530A-ECS4N-02NN/HAC defines a single purchasable EJA530A gauge pressure transmitter variant. The relevant suffix details are HAC high-accuracy selection with C capsule and no local display.

It converts gauge pressure into a control-system signal and supports configuration or diagnostic access through HART protocol. The configuration is intended for direct pressure monitoring on compatible liquid, gas or steam lines when the process and installation limits are satisfied.

For an exact spare, reconcile the nameplate with the instrument index and connection drawing. The main mismatch risk is high-accuracy calibration, capsule or HART device generation.

Technical notes
Preserve the HAC calibration records and verify traceability after replacement; a standard C-capsule unit does not retain the ordered high-accuracy performance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What performance option is designated by /HAC on EJA530A-ECS4N-02NN/HAC?
The /HAC suffix specifies the high-accuracy option for the C capsule. The calibration and ambient conditions must still fall within the official limits for that performance.
What mounting provision must be arranged separately for EJA530A-ECS4N-02NN/HAC?
No bracket is selected, so the installation must use the direct 1/2 NPT process connection or separately engineered support without loading the transmitter body.
Which precision pressure duty benefits from EJA530A-ECS4N-02NN/HAC?
It is appropriate for direct gauge-pressure measurement up to the C-capsule range where the approved uncertainty analysis justifies the /HAC high-accuracy selection.
What calibration traceability should be discussed before ordering EJA530A-ECS4N-02NN/HAC?
State the required certificate type, calibration points and accreditation expectations; only the documents expressly listed in the quotation should be treated as included.
Can a standard-accuracy unit replace EJA530A-ECS4N-02NN/HAC in a metered measurement point?
Only after the site's uncertainty calculation and quality requirements accept the change. Removing /HAC can alter the documented accuracy basis even if pressure range and threads match.
What accuracy data should accompany an EJA530A-ECS4N-02NN/HAC quotation request?
Provide the calibrated span, allowable total uncertainty, process and ambient temperatures and Yokogawa GS 01C21F01-00EN reference so the high-accuracy requirement can be reviewed.
