The Rosemount Analytical RB PDS 71-RB pH sensor data sheet details models, performance, installation options, materials, rating parameters, measurement…
The RB PDS 71-RB series includes the RB‑546 and RB‑547 pH sensors. Both models offer multiple installation configurations such as threaded straight‑in, immersion, and ball‑valve insertion, allowing flexible integration into process lines.
The sensors are constructed from chemically resistant materials like KYNAR, titanium (RB‑547), and Teflon, and feature high‑performance J‑glass electrodes with PT100 temperature compensation. The sheet lists maximum rated pressure and temperature, measurement range, and provides ordering part numbers for accessories and optional components.
| Measurement range | pH 0‑14 |
|---|---|
| Installation options | Threaded straight‑in, immersion, ball‑valve insertion (RB‑546, RB‑547) |
| Sensor body material | KYNAR (chemical‑resistant) |
| Flow cell temperature rating | 32‑122 °F (50 °C) |
| Flow cell maximum pressure | 65 psig (549 kPa) |
| Flow cell flow rate | 2‑5 gal/h (7.6‑18.9 L/h) |
The sensor can be installed as a threaded straight‑in fitting, an immersion probe, or a ball‑valve insertion unit, with specific configurations for the RB‑546 and RB‑547 models.
The sensor measures pH from 0 to 14.
