Maintenance-Free Measurement Cell

Precise Spectroscopic Online Measurement of Gases and Liquids under Harsh Process Conditions

In the chemical, petrochemical, paint & coatings and agricultural industries, process optimization is playing an increasingly important role in ensuring competitiveness.

For the sustainable success of manufacturing companies within these industries, it is therefore necessary to continuously improve existing manufacturing processes in terms of process reliability, product quality and cost reduction. These are drivers for close-meshed process monitoring and control using online analytics, especially spectroscopic methods.

However, process conditions are often adverse and require measuring components that are not only robust but also fit into the overall system. Support comes in the form of the "Excalibur HD FCP" measurement cell.

Online measurements directly in the product flow or bypass

Spectroscopic UV, Vis or NIR online measurements in real time are standard in industrial process analytical technology (PAT). They provide data on the composition and quality of liquids and gases directly from the process flow or can be used for monitoring reactions in the bypass. Based on real-time data, the effects of process parameters on product quality or the performance of downstream processes can be reliably identified and quick decisions can be made for further improvements.

Exceptionally robust measurement cell for process use

The Excalibur HD FCP measurement cell is particularly pressure and temperature resistant (up to 250 bar / 300°C) by using wear-free metal seals and sapphire optics. Maintenance-related failures or downtimes are eliminated - process costs are reduced.

The measurement cell is filled with nitrogen. The slight overpressure and the presence of a second barrier prevent the medium from escaping. This means that it is well equipped for use in demanding process environments.

The Excalibur HD FCP can be applied in potentially explosive areas (ATEX zones 1, 2, 21 and 22). It is also very flexible. The central part is interchangeable, allowing the measurement cell to be used for measurements of liquid as well as gaseous substances. The Hellma online configurator helps to adapt the Excalibur HD FCP to specific process requirements.
