Probe Extractor Mechanism

Faster Removal and Servicing of Insertion Probes without Shutting Down the Process

The Probe Extractor Mechanism is used for the controlled extraction/insertion of an in-line probe from pressurized process streams or reactors for servicing. Coupled with a gate or ball valve, these extractors have proven safe and effective in a variety of installations.  Watch the Probe Extractor Mechanism in Action

Do ALL Probe Require Servicing?

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 window must be considered when choosing sample interfaces. The Probe Extractor Mechanism makes required maintenance jobs easier, faster and safer.

Installation Examples

  • Reformer, Gasoline Blending, blender Feed Streams
  • Polyols, Polyesters, Solvent Recovery Applications

How Does the Gear-Driven Probe Extractor Mechanism Work?

The Probe 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 Probe Extractor Mechanism is purchased with an insertion probe, its conveniently assembled at the Guided Wave factory prior to shipment. This allows installation in the field to be fast and uncomplicated. Shutting down the process just to  remove the probe and clean the windows is not possible for most plants. Installing the Probe Extractor Mechanism allows maintenance of the probe while the process is running, proving continuous use of the analyzer to verify process quality.
