Figure 1.

What''s a Better Sampling Methodology for a Toxic …

2019-5-6 · Definitions. There are two prominent sampling methods used in gas detection: Sample draw and passive diffusion. A sample draw system uses a pump to draw sample back into the instrument, where it enters the sensor for analysis, and is then exhausted to the atmosphere or vent line.. Gas detection instruments with passive diffusion sensors do not use a pump to pull the sample to the sensor.

Operating principle ‐Electrochemical-type gas sensor

In order to measure the sensor’s output current, it must be connected to an external circuit. By controlling gas flowing toward the wong electrode with diffusion film, output current flowing across the external circuit will be proportional to gas concentration (see Equation 4 and the chart at the right).
