Series 1640 Floating Contact Null Switch for High and Low Actuation Visual Set Point Adjustment...Adjustable Null Zone The unique electric switch design in the 1640 is another Dwyer Instruments, Inc. innovation. The Dwyer Model 1640 Differential Pressure Switch resembles the Series 1630 switches described on the previous page. The Model 1640, however, is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch. 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. SPECIFICATIONS Service: Air and non-combustible, compatible gases. Wetted Materials: Consult factory. Temperature Limits: -30 to 110°F (- 34.4 to 43.3°C). Pressure Limits: 10 psig (68.95 kPa) continuous, 25 psig (172.4 kPa) surge. Switch Type: Single-pole double-throw (SPDT) floating contact (not snap action). Electrical Rating: Non-inductive — 2.5 A @ 110 VAC; 1.5 A @ 220 VAC; 1 A @ 24 VDC; 0.5 A @ 110 VAC; Inductive — 1 A @ 110 VAC; 0.5 A @ 220 VAC; 0.5 A @ 24 VDC (De-rate 70-80% for very slow pressure changes). Electrical Connections: 3 screw type, common, normally open and normally closed. Process Connections: 1/8? female NPT. Mounting Orientation: Diaphragm in vertical position. Consult factory for other position orientations. Set Point Adjustment: Screw type. Weight: 4 Ib, 13 oz (2.18 kg). Agency Approvals: CE. BIN F14-5 KAR
