Laser Based – Stack/Duct Monitoring

Stack/Duct (SDX) Probe Assembly

Configuration Options available

To best understand if this Measurement Head is ideal for your application, it vital to understand what is included.

The Stack/Duct (SDX) Probe Assembly has the following configurable options:

• Cable Kit Length: From 5 to 300 m of Cabling between the Stack/Duct (SDX) Probe and the GasFinder.

The Stack/Duct (SDX) Probe Assembly is comprised of the following components:

• Stack/Duct (SDX) Probe: This houses transceiver functionality and where the Fiber Optic and CAT6/5e are connected.
• High-Temperature Retro-Flange: These are like sections through a thousands of cubes and has three faces that form the inside of a cube and regardless of the angle of incidence of the incoming laser beam, the laser light is always reflected at 180° back to the Stack/Duct (SDX) Probe.

  The Components and their Function

  

  The Stack/Duct (SDX) Probe includes the following components:

  • Cable Termination Enclosure: This is where the Single Mode Fiber Optic (FC/APC Connector) and Shielded CAT6/5e (RJ45) Cabling is landed and terminated.
  • Transceiver Configuration: This contains both the transmit and receiving optics on the Optical Insert.
  • Sapphire Window: This separates the wetted process from the optical components.
  • Wetted Process Side: This is where the direct and non-contact measurements take place.

  

  The Optical Bench includes the following components:

  • Launch Optics: The Laser Light that travels from the GasFinder via Single Mode Fiber Optic Cabling is Collimated within the Optical Bench and launched from the hole on the Collecting Optics.
  • Collecting Optics: When the Laser Light is returned from the Retro-Reflector the Collecting Optics focus the Laser Light onto the Photodiode.
  • Photodiode: The Photodiode converts the collected Laser Light into a small electrical signal where the GasFinder will perform its Absorption Spectroscopy technique to very accurately and reliably determine the Path Integrated Concentration within the Active Measurement Path.
  • Not Suitable for Pressurized Use: While this has a 150# Raised Faced Flange Connection, this is not to be used in pressurized applications for both mechanical and spectroscopic limitations.

  

  The Stack/Duct (SDX) Probe includes the following components:

  • Cable Termination Enclosure:  The Optical Bench can slide back out of the Remote Point (RPX) Probe Enclosure for easy termination of the Single Mode Fiber Optic (FC/APC Connectors) and Shielded CAT6/5e (RJ45 Connectors) Cables.
  • FC/APC Connector: The Laser Light is carried from the GasFinder to the Open Path (OPX) Head via Single Mode Fiber Optic Cabling.
  • RJ45 Connector: The small electrical signal from the Photodiode is carried to the GasFinder for analysis via Shielded CAT6/5e Cabling.
  • X-ish and Y-ish Adjustments: With the use of an Allen Key, the technician can easily align the Stack/Duct (SDX) Probe to the orthogonally mounted Retro-Flange.
• High-Temperature Retro-Flange

  The High-Temperature Retro-Flange includes the following components:

  • Flanged Wetted Process Connection:  The Optical Bench can slide back out of the Remote Point (RPX) Probe Enclosure for easy termination of the Single Mode Fiber Optic (FC/APC Connectors) and Shielded CAT6/5e (RJ45 Connectors) Cables.
  • IMOS Retro-Array: These are like sections through a thousands of cubes and has three faces that form the inside of a cube and regardless of the angle of incidence of the incoming laser beam, the laser light is always reflected at 180° back to the Stack/Duct (SDX) Probe.
  • Sapphire Window: This separates the wetted process from the optical components.
  • Not Suitable for Pressurized Use: While this has a 150# Raised Faced Flange Connection, this is not to be used in pressurized applications for both mechanical and spectroscopic limitations.
• Purge Insert

  Keeping the Windows Clean

  The Purge Insert is mounted between either the Stack/Duct (SDX) Probe and the Process Flange to provide a location to connect the purge medium (e.g. Instrument Air, Nitrogen, etc.).

  

  The design of the Purge Insert forces the purge medium past the windows of the Stack/Duct (SDX) Probe and the Retro-Flange to keep the windows both clean and cooler.
