Particle Imaging

• Shadow images of particles passing through a collimated laser beam are projected onto a linear array of 64 photodetectors to determine presence of particles.
• Particle images are reconstructed from individual “slices,” where a slice is the state of the 64-element linear array at a given moment in time.

• Technique : Optical Array Probe with 64 elements: 62 sizing elements, end diode rejection
• Measured Particle Size Range : 100 µm – 6.2 mm
• Sample Area : 260 mm x 6.2 mm for standard configuration (no Korolev tips)
• Upper Concentration Range : 100 particles/cm3
• Air Speed Range : 10 – 200 m/sec
• Number of Size Bins : 62
• Sampling Frequency : Asynchronous, 0.1 – 10 Hz. 1-second sampling is typical
• Laser : 660 nm
• Data System Interface: : Two channels: RS-422: 56,000 Baud Rate; High-Speed Serial: 4 x 106 Baud Rate (RS-422 only)
• Weight : 
• 21 lbs./9.5 kg in DMT canister

The Lifecycle Care Program ensures PIP integrity and performance vital to your research mission for 3 years or 3 calls (whichever comes first). When conducting complex and time intensive laboratory or field measurements it is critical to avoid down time, and ensure data collection accuracy. The program consists of 3 key deliverables for each year or call:

• Instrument Logistics
• Instrument Integrity
• Instrument Performance

Lifecycle Care Program Includes:

LOGISTICS

• Shipping to and from Droplet Measurement Technologies facility
• Customs handling, including CARNET ATA if required

INTEGRITY

• Incoming instrument evaluation and health check

PERFORMANCE

• Software and firmware validation
• 100%-unit functionality test
• Calibration data
• Calibration report
• Certificate of calibration

At times, our technician might discover an instrument issue, which might not be covered by the Lifecycle Care Program or by our product warranty. In such case we will reach out to you with a service & repair estimate to allow you to provide us with the next steps of action.
