Principle of Operation
All IBR laser diode sensors from 1.3 µm to 800 µm
use the extinction (blockage) technique to capture particle size
and quantity. Additionally, they view the full sample flowing through
the sensor cell, resulting in excellent resolution exceeding all
industry standards.
Uses:
- Municipal water system
- Filter testing
- Hydraulic fluid monitoring
- Particle contamination detection
- Manufacturing process monitoring
- System clean-up alarm
- Replace microscope particle counts

Benefits
- Interchangeable in critical locations with reproducible results
- Long life
- Rugged construction
- Over 2,000 units in field and not one defective cell yet
- Easily cleanable
- On-line monitoring saves time and effort and prevents errors
Features
- Approximately 7.5 year MTBF laser life
- Capable of field calibration
- Insensitive to color of fluid
- Stain/quartz wetted surfaces
- Repeatable and reliable
Calibration
Can be done on site or at our facility. IBR can
calibrate to:
- ASTM F-658-87 Polystyrene spheres
- ISO 4402 ACFTD in oil
- ANSI-B93.28-1973 ACFTD in 5606 oil

Higher concentration of particles
If counting higher concentrations is required,
IBR makes diluters to cover every need. In addition, IBR offers the
D series of sensors, designed with a larger orifice that resists
clogging.
Temperature
32º F to 150º F
Aggressive Chemicals
All of the above sensors use Viton seals, optional Kalrez seals are available.
Flow Path Materials
Stainless steel and quartz, as well as appropriate seals
Pressure Limits
Typical sensor cell is 1,000 psig, however, inlet and outlet fittings are the determining factor for the pressure limit.
†Coincidence Loss
Coincidence loss occurs as a result of some particles preventing
the
sensor
from recording the presence other particles behind them. Loss due to coincidence
varies according to particle concentration, particle distribution and size. For
more information on coincidence loss, please contact us. |
