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.
