This component is used in the following industrial products
The Automated Chemical Filtration and Separation System is an integrated industrial system designed for continuous, automated filtration and separation of chemical process streams.
A combined unit that removes oxygen from beverage containers by first evacuating air and then flushing with inert gas to prevent oxidation and extend shelf life.
A system that creates and maintains controlled vacuum or pressure conditions within a crystallization vessel to facilitate chemical crystallization processes.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
10 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Pressure sensors monitor differential pressure across filters. When pressure exceeds setpoints (indicating clogging), they trigger alarms or automatic backwash cycles, preventing rupture, reduced efficiency, or chemical bypass.
For highly corrosive media (acids, chlorides), use sensors with Hastelloy C-276 or Tantalum diaphragms and PTFE seals. 316L stainless steel suffices for moderate chemicals. Always verify chemical compatibility charts.
Calibration involves applying known pressures (deadweight tester or precision calibrator) and adjusting zero and span via HART communicator or control system. ISO 9001 requires periodic calibration (typically annually) with traceable standards.
