Features:
- The NF2-approved low-draft configuration uses the 0.1 to 1 kPa (0.4 to 4 inH2O) capsule, horizontal piping with left-side high pressure and 1/2 NPT female, two entries with blind plug.
- The NF2-approved low-draft configuration provides 4–20 mA DC with digital communication through HART 5/HART 7 protocol, with digital indicator.
- The NF2-approved low-draft configuration combines 1/4 NPT female cover-flange pressure ports without separate process connectors, S-code wetted assembly with Hastelloy C-276 diaphragm and 304 SST flat 2-inch pipe bracket.
The EJA120E-JES5J-917DB/NF2 suffix sequence selects the 0.1 to 1 kPa draft capsule, no process connectors and the /NF2 approval within the EJA120E platform.
It resolves very low differential pressure for draft, airflow or filter-monitoring duties and supports remote setup through HART 5/HART 7 protocol.
Confirm draft capsule, high-pressure-side orientation or intrinsic-safety suffix before accepting the unit as a mechanical, electrical or functional replacement.
Availability is subject to Apter Power inventory and sourcing confirmation.

- The NF2-approved low-draft configuration monitors furnace, duct or air-handling draft where a very low differential-pressure capsule is required.
- The NF2-approved low-draft configuration supports clean-room, filter or fan supervision when the impulse-line design protects the low-pressure measurement.
- The NF2-approved low-draft configuration provides draft feedback to combustion, ventilation or environmental control systems through a compatible host.
- The standard electronics are specified for -40 to 85°C (-40 to 185°F), or -30 to 80°C with LCD, subject to the tighter limit imposed by the selected indicator or approval.
- The process interface follows -40 to 120°C (-40 to 248°F), with fill-fluid and approval options checked for any reduced range.
- Temperature effects are evaluated against the selected 0.1 to 1 kPa (0.4 to 4 inH2O) capsule rather than a neighboring measurement code.
- Pressure is converted to 4–20 mA DC with digital communication, while HART 5/HART 7 protocol exposes measurement and diagnostic variables to a compatible host.
- Local visibility is provided by digital indicator, subject to the selected display and range-setting capability.
- The configured range of -1 to 1 kPa (-4 to 4 inH2O) must be compared with the process design limits during commissioning.
- The host must use a device description that matches the installed HART 5/HART 7 protocol revision and transmitter electronics.
- Firmware identification should be read from the live device before loading parameters or selecting a replacement file.
- Local display functions depend on the digital indicator and cannot be inferred from the base transmitter family.
