Excerpt from A Prototype Semi-Automated System for Measuring Air Infiltration in Buildings Using Sulfur Hexafluoride as a Tracer
Small modifications have been made in the system since it was originally designed. For example, stepping switch (2) and sample injection solenoid (12) are Operated with rectified current as shown in Figure 2. This permits use of lower voltage and reduces electrical noise. Other modifications include padding of the plunger of solenoid (12) to reduce mechanical im pact and introduction of screens in the sampling lines to keep large particles of dirt out of the sampling solenoids and the pump. Also, a 2 - port atomizer bulb with check valves was placed in the output of pump because it was found that otherwise samples were contaminated with ambient air at the pump output during the return stroke of the pump.
