The Deltabar S series includes the PMD75, FMD77 and FMD78 differential pressure transmitters. They are metal‑membrane sensors used for flow, level, pressure and differential‑pressure measurements in industrial processes, with options for diaphragm‑sealed systems and high‑temperature operation.
The manual contains full technical parameters, installation guidelines, wiring diagrams, communication protocol details (HART, PROFIBUS PA, FOUNDATION Fieldbus), safety certifications (SIL 3, IEC 61508, TÜV SÜD) and ordering information for accessories and optional options. This manual is written in Chinese.
| Reference measurement accuracy (PMD75) | ±0.035 % of span |
|---|---|
| Supply voltage (non‑explosive) | 10.5–45 V DC (HART) / 9–32 V DC (PROFIBUS PA, FOUNDATION Fieldbus) |
| Output signal | 4–20 mA (HART, PROFIBUS PA, FOUNDATION Fieldbus) |
Non‑explosion‑proof units need 10.5–45 V DC for HART and 9–32 V DC for PROFIBUS PA or FOUNDATION Fieldbus.
The transmitter is certified to SIL 3 and complies with IEC 61508, with TÜV SÜD approval.
