snippet<p><strong>Dwyer, 1640-3KPA, Series 1640 Floating Contact Null Switch For High And Low Actuation 1.0 - 3.0 kPa </strong> </p> <p>VisualSet Point Adjustment, Adjustable Null Zone </p> <p><strong>The unique electric switch design in the 1640 is another Dwyer Instrument, Inc. innovation. </strong> The Dwyer&#174; Model 1640 Differential Pressure Switch resembles the Series 1630 switches. However, the Model 1640 is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch. </p> <p>Drawing shows the switching action schematically. As the diaphragm moves in response to pressure changes, it moves the floating contact to cause switching action at two preset points with no switching action between these points. The "high" circuit will be closed when rising pressure differential reaches the preset level. The "low" circuit will be closed when falling pressure differential reaches the preset level. </p> <p>A typical example of usage is to position motorized dampers when static pressure in a duct system reaches a desired maximum and reposition the dampers when the static pressure falls to a pre-established minimum. By using a Pitot tube sensing element the Model 1640 switch can serve in the same way to control air velocity and maintain a constant volume of air in a supply duct. </p> <p><strong>Approvals </strong> CE Approval. </p> <p><strong>Caution: For Use Only With Air Or Compatible Gases. </strong> </p>
