SOLUTION SHEET

Mixed-brand LDV/PDPA solutions
Upgrade unsupported systems

Fiberoptic LDV transceiver and couplers of a competing brand, connected to Dantec FiberFlow Laser
Transmitter and BSA processor

Protect your investment by replacing only defective system components
If you have an unsupported LDV or PDPA system, we can help.
We can replace fiberoptic transceiver or transmitter probes by adding Dantec couplers
and fiberoptic LDV transceiver probes to your legacy beam generator / laser sourceand connect the receiving fiber to your legacy signal processor.
We can also replace your legacy beam generator / laser source unit by one or more
Dantec FiberFlow Laser Transmitters.
Finally, if your processor is defective or software out of date, we can replace it with aDantec BSA processor and associated BSA Flow Software

Upgrade paths•

Reduce upgrade cost by replacing only the faulty or unsupported parts•

Replace fiberoptic transceiver or transmitter probes, keep your beam generator / laser
source and processor (and photodetector unit)•

Replace transceiver laser module, keep processor (and photodetector unit)•

Replace processor, keep beam generator/laser source and transceiver or transmitter
probesReplace transceiver probe and couplers, keep beam generator/laser
source and processor/software

If your fiberoptic transceiver or transmitter probe has gone out of alignmentor has damaged optical fibers, it can be replaced by a Dantec FiberFlow probe
and associated fiber couplers. A range of probe sizes from 14 mm to 112 mm
diameter, as well as beam expanders and probe supports, are available, tocover many applications.
Please consult the data sheet “FiberFlow Probes” for further details.

FiberFlow probes in 4 sizes

The receiving fiber(s) of the Dantec probe(s) can be connected to the colorbar
of a photo-detector unit or a legacy processor via an adapter.
Our probe mounts fit directly to 90 x 90 mm Bosch rails.

The beam generator / laser source can be replaced by one or more FiberFlow
Laser Transmitters. Each unit includes a laser, beam splitting and frequency
shifting optics. 2D and 3d systems are configured by using two or three
FiberFlow Laser Transmitters.
Your couplers can be connected to the FiberFlow unit, so that you can continue
using your fiberoptic transceiver or transmitter probe.
A Bragg cell driver unit is needed to adapt the Bragg Out voltages from yourlegacy processor to the Dantec Bragg cells.
Please consult the solution sheet “FiberFlow LDA (Laser Doppler Anemometry)systems” for further details.

2Replace LDV optics, keep processor/software

The LDV optics can be replaced by one or more FiberFlow Laser Transmittersand Probes.
A Bragg cell driver unit is needed to adapt the Bragg Out voltages from yourlegacy processor to the Dantec Bragg cells.

Replace processor/software, keep LDV optics

BSA processor

A Dantec BSA F processor for LDV can replace a legacy processor.
A Dantec BSA P processor for PDPA can replace a legacy PDPA processor ifthe PDPA receiver is replaced by a Dantec FiberPDA or HiDense receiver at thesame time.
BSA processors have built-in color filters, beam splitters and photo-multipliers,
and are available for the most common Ar-Ion laser, Fiber laser and DPSS laser
wavelengths.
Please consult the data sheet “Burst Spectrum Analyzer (BSA) for furtherdetails.

BSA Flow Software
The LDV or PDPA system is run from thepowerful BSA Flow software.
BSA Flow software controls the BSA processor,lasers and traverse system and has manyplotting and data exchange features.
Please consult the data sheet “BSA Flow
Software” for further details.
