The ASI Model ESP-050 Series Direct Extraction (“ESP”) sampling probe is designed to function as an instrument for filtering and measuring low-flow samples. This is a variation of the Straight Extractive Sample Tip (aka “SEST”). The ESP probe prepares the sample from the stack (conduit or process) so that it can be accurately and accurately measured by the analyzer (usually a “source level” analyzer). The ESP-050 probe, connected to an external suction pump (built into your analyzer or other mechanical or pneumatic educational pump), extracts a continuous sample from the source gas stream. The gas sample is then passed consecutively through coarse and fine particulate filters (mesh screen, quartz wool and sintered frit), a critical orifice of preselected glass or metal, and then is transported to the analyzer. The critical orifice (sonic orifice) serves as a flow measurement component to ensure a constant and precise flow rate for gas extraction. A secondary line, called a “service line”, is also located at the rear of the probe. This line can be used for calibration gas, purging (purging), and monitoring sample pressure.
