Particle Measuring Systems High Pressure Gas Probe System, HPGP-101-C, monitors contaminants in process gases at line pressure. This HPGP-101-C system includes the probe along with a PDS-PA data system, which collects and reports data in various formats.
Process gases are used regularly in manufacturing environments. Monitoring the
particulate level in gases is best achieved at line pressure. The High
Pressure Gas Probe, Model HPGP, operates at pressures from 40 to 150 psig.
Sizing sensitivity is available at 0.1 micron with a flow rate of 0.1 SCFM. The
probe is contained in a cylindrical pressure vessel, which serves as a safety
containment housing. During operation, the contaminant vessel is pressurized
with dry nitrogen. If the pressure vessel leaks to ambient or if there is an
internal gas leak into the vessel, power is disabled. The metal inlet fitting
surfaces are electro-polished stainless steel providing compatibility with many
non-toxic gases and aerosols.
Each system includes a HPGP and a PDS-PA data acquisition system. Up to eight
sizing channels are displayed on a 5-inch CRT for the operator to view. The
information is presented in a tabular format or as a histogram. Data can be
displayed representing differential or cumulative counts.
