Configuration and RFQ Guide for Siemens 7MF0340-1HV01-5AF2-Z+A00+C11+C14+C20+E01+Y01 pressure transmitter with 7MF0812-1PA15-0BA0-Z+C12+C20+D66+D88 remote seal
Siemens 7MF0340-1HV01-5AF2-Z+A00+C11+C14+C20+E01+Y01 pressure transmitter with 7MF0812-1PA15-0BA0-Z+C12+C20+D66+D88 remote seal is a configured Siemens SITRANS P320 differential-pressure measurement package. The transmitter order code identifies a PN160 HART unit for differential pressure and flow measurement, while the separate 7MF0812 order code identifies a flange-type remote-seal arrangement for a differential-pressure transmitter.

Image scope notice: the supplied photograph shows a Siemens SITRANS pressure-transmitter body in its packaging. The two flange remote seals, flexible capillaries and complete option labels are not fully visible. Use the full transmitter and remote-seal order codes—not appearance alone—to confirm the quoted assembly.
What the 7MF0340 transmitter code represents
Siemens catalog information identifies 7MF0340 as a SITRANS P320 pressure transmitter for differential pressure and flow with a maximum allowable working pressure class of PN160. The 1HV01 measuring-cell selection is associated with a maximum measuring span of 600 mbar and silicone-oil filling.
The 5AF2 execution is a HART 4–20 mA instrument with local display in a dual-chamber housing configuration. For this order, the process interface is prepared for connection to diaphragm seals rather than treated as a standard direct-process flange arrangement.
How the 7MF0812 remote-seal position is used
The 7MF0812 family covers flange-type diaphragm seals connected by flexible capillaries for SITRANS P320/P420 differential-pressure and flow transmitters. Siemens ordering data states that the transmitter is ordered as a separate position and that the 7MF0812 scope for differential-pressure service contains two remote-seal units.
For the 7MF0812-1PA15-0BA0 base configuration, project records should confirm the flange standard and size, pressure class, capillary length, fill fluid, diaphragm material, coating and extension. These attributes affect mechanical fit, process compatibility, response time and permissible temperature conditions.
Selected remote-seal option codes
- C12: EN 10204-3.1 inspection certificate for body and diaphragm materials.
- C20: factory functional-safety certificate for SIL2/3 suitability under IEC 61508 and IEC 61511, including the declaration of conformity.
- D66: specified ambient-temperature range of +10 to +50 °C as the preset process-condition selection.
- D88: extended negative-pressure service for differential-pressure transmitters.
The transmitter option string +A00+C11+C14+C20+E01+Y01 must likewise be preserved in full. Do not assume that identically shaped P320 transmitters carry the same certificates, approvals, mounting provisions, tag data or factory configuration.
Why the transmitter and remote seals must be reviewed together
With Siemens 7MF0340-1HV01-5AF2-Z+A00+C11+C14+C20+E01+Y01 pressure transmitter with 7MF0812-1PA15-0BA0-Z+C12+C20+D66+D88 remote seal, the filled transmitter–capillary–seal system behaves as one measurement assembly. Fill-fluid expansion, capillary length, diaphragm stiffness, elevation difference, ambient temperature and process temperature can influence zero shift and dynamic response.
The lowest permissible pressure rating among the transmitter, diaphragm seals, flange connection and installation determines the usable system limit. Process engineers should also check wetted-material compatibility, gasket selection, flange facing, bolt loading, vacuum conditions and installation orientation.
Pre-order engineering checklist
- Keep both complete order codes and all + option codes on the same RFQ.
- Confirm the measuring range, calibrated lower/upper values, engineering unit and required HART setup.
- Verify process pressure, static pressure, temperature, vacuum conditions and expected overloads.
- Confirm flange standard, nominal size, pressure class, facing and gasket requirements at both taps.
- Check capillary length, protective routing, mounting elevation and equal-temperature installation practice.
- Review diaphragm and other wetted materials against the process medium.
- Specify tag text, certificates, SIL documents, quantity, destination and target delivery date.
A clear photograph of the transmitter nameplate, remote-seal tags and both flange assemblies is valuable for replacement enquiries. If the installed unit is already filled and calibrated as one system, do not separate or substitute individual filled components without an engineering and factory compatibility review.
Buyer questions answered
Is 7MF0340-1HV01-5AF2 a gauge-pressure transmitter?
No. The 7MF0340 family is used for differential pressure and flow measurement. Gauge-pressure P320 variants use other 7MF03 prefixes and configurations.
Why is 7MF0812 ordered separately?
Siemens treats the remote-seal system as a separately configured order position. This allows the flange, capillary, fill fluid, material and special service options to be defined for the application.
Does the supplied photo show the complete remote-seal assembly?
The photo clearly shows the transmitter body, but it does not fully show both remote seals and flexible capillaries. The order codes remain the controlling identification.
What information is most useful for a quotation?
Send both full Siemens order codes, calibrated range, process and ambient temperatures, pressure/vacuum conditions, flange data, wetted-material requirements, certificates, quantity and delivery destination.
HKXY quotation support for the configured SITRANS P320 package
HKXY can prepare a configuration-specific quotation for Siemens 7MF0340-1HV01-5AF2-Z+A00+C11+C14+C20+E01+Y01 pressure transmitter with 7MF0812-1PA15-0BA0-Z+C12+C20+D66+D88 remote seal. Keeping the transmitter and remote-seal positions together helps purchasing and engineering teams compare the required HART transmitter, filled capillary system, flange interfaces and documentation scope before the order is released.
