511 OEM pressure transmitter, maximum pressure 600 bar, accuracy 0.3%
The 511 series OEM pressure transmitters from Huba Control are compact, rugged devices designed for demanding industrial applications. They feature a ceramic sensing element, IP67 protection, and a patented media‑stop system that prevents leakage when the rupture pressure is exceeded.
The manual covers technical specifications, pressure ranges, accuracy, temperature limits, electrical connections, output options (4‑20 mA, ratiometric voltage), and test data such as shock and vibration resistance. Installation variants, sealing materials, and wiring diagrams are also described.
| Relative pressure range | -1 to 600 bar |
|---|---|
| Absolute pressure range | 0 to 25 bar |
| IP protection rating | IP67 |
| Housing material | Stainless steel 1.4305 (AISI 303) |
| Sealing material (media stopper) | PPS |
| Ambient temperature limit | up to 85 °C (up to 125 °C for AMP versions) |
| Accuracy | ±0.3 % FS (linearity) / ±0.5 % FS (hysteresis & repeatability) |
| Response time | < 2 ms |
| Electrical strength | 500 VDC (optional 1000 VDC) |
It measures relative pressure from –1 bar up to 600 bar and absolute pressure from 0 bar up to 25 bar.
A patented media‑stop system blocks media egress when the rupture pressure (over 40 bar nominal) is exceeded.
The dynamic response time is less than 2 ms.
