Back pressure regulators
Used after pressure reduction to maintain a constant upstream pressure, surplus sample pressure is blown off in the drain, equilizing fluctuations in the sample supply pressure. This will result in a constant flow through the chemical sensors flow cells. Again we are free to chose the best solution on the market, the best price/performance ratio for the application with high or low capacity and a fixed pressure or adjustable. Important for selecting the right type,
- Fluctuation range of sample pressure,
- Sample cooler capacity as the (blow off) flow could get (too) high.
- Debris to be expected?
- Maximum allowable pressure analyzing equipment?
- Suitable for pressure reducer caracteristics?
