Key Technical Features for SEO Content
1. Ceramic Capacitive Measuring Cell (Ceraphire®)
The PMP51B’s capacitive ceramic sensor offers distinct advantages over conventional piezoresistive designs:-25
Vacuum-resistant — withstands full vacuum down to 50 mbar absolute without damage-2
Oil-free operation — no fill oil required for most measuring ranges, eliminating thermal drift and reducing maintenance
High overload resistance — withstands up to 600 bar overpressure (9,000 psi)-2
Chemical resistance — 99.9% pure Al₂O₃ ceramic is highly resistant to corrosive and abrasive media-25
Integrated membrane breakage detection — ensures process safety and prevents media migration-25
2. Integrated Diagnostics (HistoROM®)
The PMP51B incorporates advanced diagnostic capabilities:
Automatic sensor health check
Diaphragm rupture detection (critical for safety applications)
Logs process and device events (up to 1,000 entries)
Undervoltage detection prevents dangerous plant conditions and frozen current values-4
- Flexible Communication Options
All E&H PMP51B pressure transmitter variants support multiple communication protocols:-2
4…20 mA analog — legacy compatibility
4…20 mA HART (version 7) — standard for most applications
PROFINET with Ethernet-APL — digital integration for Industry 4.0
Bluetooth® (SmartBlue App) — wireless remote configuration, commissioning, and proof testing from mobile devices without process interruption-2
HART protocol-specific data: Manufacturer ID 17 (0x11 hex), Device Type ID 0x112A, HART specification 7, minimum load resistance 250 Ω. Supported functions include burst mode, additional transmitter status, device locking, and multidrop operation.-82
4. FLEX Selection Concept
Endress+Hauser offers four product tiers to match application requirements:-1
| Tier | Description |
