Fast and Consistent Turnaround Times for your Serviced Equipment


The ASI Model DP-049 Series In-Situ Dilution Probe is designed to function as a sample conditioning and transport system, the Dilution Probe performs four critical functions to prepare the sample from the stack (duct or process) so that it can be measured accurately and precisely by the analyzer (typically an "ambient level" analyzer). The system uses an air driven aspirator which extracts a continuous and precise low-flow sample from the source gas stream. It is then passed consecutively through coarse and fine particulate filters, a preselected glass or metal orifice, and diluted with the motive air within the probe aspirator. This process has now reduced the dew point of the source gas sample to below that of the ambient air. It prepared the often warm, wet, sticky and particulate laden sample, so that it can be transported (at a positive pressure) via an unheated umbilical line to the analyzer, up to 300FT (100M) away.

 


The internal diluting aspirators we utilize in our Dilution Probes are manufactured and calibrated to meet the highest performance efficiencies on the market. This translates into stability and lower dilution air consumption.

Reach a minimum vacuum of .47 bar (13.87"Hg) at a low 2.5 bar (36.25psi) dilution air pressure.
Maintain vacuum levels above the .47 bar through dilution air pressures up to 6 bar.
Diluted sample flow rates in range of 4.5 to 12 l/min (dependent on dilution air pressure setting).
Operating temperatures up to 750°F (400°C), or High Temp versions to 1000°F (540°C)

Filters particulate using both coarse and fine filtering methods
Reduces moisture content to levels below the dew point
Dilutes sample to more accurately measured concentrations (dilution ratios from 12:1 to 350:1)
Precise low-flow sample flow rates (standard orifice sizes from 20ml/min to 500ml/min)

Wetted parts from corrosion resistant Inconel-600®
Many critical orifice types available (Standard Glass, Quartz, Monel-400, or Stainless-316)

Our dilution probes require no changes to dilution probe controller configurations and settings or analyzer settings (aside from any typical adjustments required during your normal diluting probe/CEMS calibrations) when retrofitting from an old EPM dilution probe. We also offer a variety support flange options. This will make the probe compatible with any existing probe extension pipe assembly, and compatible with new or old model probe heaters (using one of two types of coarse inlet filters we offer).
