Sartorius Process Refractometers
Monitoring and control of process streams is vital for achieving optimal product quality. Rapid, reliable, und exact determination of the concentration, identity, and purity of the components in your process stream is a crucial part of effective process control.
Process refractometry is a nondestructive, online measurement technology widely used in various industries to control liquid or paste-like process streams. Sartorius process refractometers are robust and easy to operate and facilitate extremely accurate analysis – even in opaque, colored, or particle-containing streams.
- Exact & rapid online determination of concentration, identity, and purity
- Proven & reliable technology for a wide range of applications
- Proprietary technologies for the highest degree of accuracy: PES, highest resolution, and cleaning automation
With PMD700 process refractometers, widely used and proven technology has been highly integrated to exceed the special requirements of process control.
Accurate determination of concentration also calls for exact temperature compensation. The placement of the temperature sensor is crucial in this application. With the unique Sartorius prism embedded sensor (PES), located in the prism near the measurement point, the highest degree of accuracy in temperature determination can be reached.
Sartorius process refractometers with an unmatched resolution as low as 0.002 Brix (eq. 20 mg sugar per liter) can detect the slightest changes in your processes and enables control schemes that could not be implemented in the past.
Cleaning has many facets with the PMD700. The sapphire prism of the PMD700 can be cleaned in place, even by mechanical means or using high-temperature cleaning solutions. The IP65 protection rating of the PMD700 allows thoroughly cleaning from the outside.
Several output options and automation options are integrated in the electronics – without any additional electronic unit. Based on the derived information, data can be transferred via serial, analog, or digital outputs. The latter can be programmed to switch valves based on special process conditions.
