Back pressure regulators

Used after pressure reduction to maintain constant upstream pressure, surplus sample pressure is blown off in the drain, equalizing fluctuations in the sample supply pressure. This will result in a constant flow through the chemical sensors’ flow cells. Again we are free to choose 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 characteristics?
