Features:
- SITRANS P320 converts differential pressure into a two-wire 4-20 mA signal.
- HART communication shares the analog loop for configuration and device data.
- A stainless-steel oval-flange process assembly applies pressure to the filled measuring cell.
The order code fixes the pressure class, span, wetted materials, display, housing and cable entries.
The local display and external push buttons provide on-device observation and setup.
Process sealing, manifold alignment and loop grounding belong to separate installation checks.
The Siemens 7MF0340-1DM01-5AF2-Z A01+E01+H01 SITRANS P320 Differential Pressure Transmitter is listed as available from the original manufacturer (OEM).

Following process pressure through the measuring assembly
- High and low sides: The manifold routes each process pressure to its assigned oval-flange port.
- Isolation diaphragms: Stainless-steel diaphragms separate the process medium from the cell fill fluid.
- Filled cell: Silicone oil transfers the differential force to the sensing element.
- Converted value: Electronics translate the measured difference into loop current and HART data.
Keeping analog measurement and digital communication on one pair
- Loop supply: The control loop powers the transmitter and carries the 4–20 mA value.
- Digital overlay: HART exchanges settings and diagnostics without replacing the analog current.
- Control input: The receiving analog channel reads the current assigned to the measured differential pressure.
- Commissioning check: Polarity, loop resistance, shielding and device address are verified together.
Matching flange hardware to the installed pressure connection
- Pressure class: The PN160 configuration defines the mechanical pressure boundary.
- Fastening thread: M10 flange hardware belongs to this configured pressure class.
- Wetted material: 316L stainless steel is retained across the documented diaphragm and flange surfaces.
- Manifold fit: Port spacing, seals and bolt engagement are checked before pressure is applied.
Separating field wiring from measurement electronics
- Cable entries: Two M20 x 1.5 openings accept the documented glands or plugs.
- Terminal chamber: Loop conductors terminate away from the sensing electronics.
- Local indication: The fitted display presents the transmitter value at the device.
- External control: Covered push buttons allow local operation while retaining the enclosure arrangement.
