1 DW Pressure Wave Switches

2 Pressure Wave Switches Series D1 Well-proven Technology Robust design All-purpose Pressure Wave Switch The compressed volume of air inside the signal sensor is transfered via a connecting hose to the pressure wave switch. The diaphragm in the switch is deflected by the rise in pressure thus closing (or opening) the electrical contact. Series D1 The D1 series pressure wave switches are: available in 5 different versions Switching Possibilities Converting the function to one of the four possible methods is accomplished by: exchanging the connecting hose regulation of the contact screw Operating position Neutral position Pressure closes Pressure opens Suction closes Suction opens Electrical Durability is dependent largely on the contact loading. for pressures < 3 mbar it is recommended that contact protection relays (DWR) are installed The contact should not be loaded below 24 V/20 ma Bircher Reglomat AG, Wiesengasse 20, CH-8222 Beringen, Switzerland, Phone +41 (0) , Fax +41 (0)

3 Length of Connections The optimal length of hose between the signal sensor and the switch should not exceed a length of 10 metres. The internal diameter should be 2 mm and the outside diameter at least 4 mm. DW10s Plug type DW-Switch connection on the side Factory settings 46,5 Activating Pressure The airwave switches are adjusted to an activating pressure of 2 mbar, pressure closes. Switches with different settings (normally closed, pressure etc.) on request Valve Orifice An equalisation of atmospheric or temperature fluctuations is provided by a valve orifice for our profiles (up to 3500 cm 3 ).
