The table separates family facts from option-dependent values. In addition, use the official reference and the installed nameplate to confirm electrical, dimensional and approval details.
What the code identifies
The complete option code defines the electrical, mechanical, communication and approval details. Compare the installed label with the official reference before purchase. In practice, the published family gives engineers the starting point. Next, compare the full code, nameplate and installation record before releasing a replacement.
Field checks
Before quotation, compare the following points for FMX21-AA121HGD15A+POPS. Then record the result in the purchasing file:
- Measuring range
- Cable length
- Reference tube
- Diaphragm material
- Installation depth
- Output
For a reliable technical record, attach a nameplate image, the existing wiring or process connection drawing, and the installed transmitter or control-system reference. As a result, engineering can separate a family match from an exact replacement.
Service handover
First, record the operating medium, temperature and pressure conditions where relevant. Next, confirm isolation, grounding, seals, orientation, cable condition and commissioning responsibility before removal or installation. After start-up, save the measured value, alarm behavior, communication status and calibration or zeroing result. Finally, keep that evidence with the maintenance work order so the next technician can compare the replacement with the same operating conditions.
Availability request
HKXY Instruments can check the complete E+H code, current availability, price, lead time, export packing and supporting documents. Meanwhile, use the official Endress+Hauser product reference to compare the technical boundary. Finally, send the installed label and quantity for a precise quotation.
