Servicing ALL Probes and Flow Cell Insertion probes interface the analyzer to the process or sample, and regardless of the manufacturer, all probes used for absorption spectroscopy must be referenced (or zeroed) periodically and the windows occasionally cleaned. Therefore, practical methods for maintenance of the probe or access to the windows must be considered when choosing new sample interfaces.
Guided Wave’s Extractor Mechanism can be used for the controlled extraction of an in-line probe from pressurized process streams or reactors. Coupled with a gate or ball valve, these extractors have proven safe and effective in a variety of installations.
• Reformer, Gasoline Blending, Blender Feed Streams
• Polyols, Polyesters, Solvent Recovery Applications
The Extractor Mechanism utilizes a pneumatic drill to extract and insert the probe from the assembly via a gear mechanism. It may also be operated by a hand-held crank if drills are not permitted in the areas. When the Extractor Mechanism is purchased with an insertion probe, its conveniently assembled at the Guided Wave factory prior to shipment, allowing installation in the field to be fast and uncomplicated. Shutting down the process just to remove the probe and clean the windows isn’t possible for most plants. Installing the Extractor Mechanism allows a way to maintain the probe while the process is running, thus allowing continued use of the analyzer to verify process quality.
Benefits of Using the Extraction Mechanism
• Quick and easy window cleaning without interruption in your process
• Works with insertion probes in service at pressures of up to 700 psi (48 bar)
• Custom extractors with different mounting flanges available
• Custom materials of construction available
• Installs easily on a 2 inch 300# flange of a gate or ball valve (other options available)
• Compatible with Guided Wave and other brands of probes
WATCH EXTRACTOR MECHANISM IN ACTION
“The method in which the probe is secured and installed in the process line is critical for safety and performance reasons. Additionally, the probe should be installed so that plant personnel can reliably remove and reinstall it in the same position each time. And that’s the beauty of the Extractor Mechanism – it achieves this goal in a superior way.” – James Low, Guided Wave Sales & Support Director James Low, Guided Wave Sales & Support Director
