| Application
|
 | SAFE-DRIVE Process Refractometer PR-23-SD for measuring black liquor dry solids and green liquor density or TTA in kraft chemical recovery process. Vaisala SAFE-DRIVE design allows for safe and easy insertion and retraction of the sensor under full operating pressure without having to shut down the process. | Refractive Index range: | Full range, nD = 1.3200...1.5300 (corresponds to 0...100 % b.w.) | | Accuracy: | Refractive index nD ±0.0002 (typically corresponds to ± 0.1% by weight)
Repeatability nD ±0.0001 (typically corresponds to ±0.05% by weight) | | Speed of response: | 1 s undamped, damping time selectable up to 5 min | | Instrument verification: | According to ISO 9000 quality system: with standard R.I. liquids and
Transmitter's menu guided procedure | | Ambient temperature: | Sensor: max. 45°C (113°F), min. -20°C (-4°F)
Indicating transmitter: max. 50°C (122°F), min. 0°C (32°F) |
