Proof pressure is the maximum pressure which may be applied without causing damage to the sensing element. The output signal of all BSW...D-PCB is proportional to the pressure applied to port P2, relative to port P1, e.g. the output signal increases when vacuum is applied to port P1 relative to port P2. The output signal of all BSW...A-PCB is proportional to the absolute pressure applied to port P1. Span is the algebraic difference between the output at full scale pressure and offset. Non-linearity refers to the Best Straight Line fit measured for offset, full scale and 1/2 full scale pressure. Temperature shift tested and guaranteed at 70°C relative to 25°C. All specs are shown relative to 25°C. Difference in output/switch point at any pressure within the operating pressure range and temperature within 0 - 70°C after: a) 1000 temperature cycles, 0 - 70°C b) 1 million pressure cycles 0 bar to full scale pressure switching Hysteresis setting has a direct influence on the switching points output when the pressure increases or decreases. The switching points can be calculated as follows: Output going active (LED on) when pressure exceeds SET POINT + hysteresis/2 Output going inactive (LED off) when pressure falls below SET POINT - hysteresis/2 pressure setpoint 1/2 1/2 hyst. hyst. 2/4 March 2001 / 016 www.sensortechnics.com BSW Series Solid state pressure switch with analog output PHYSICAL DIMENSIONS BSW...V-PCB 2 x 3.5 diam. 10.3 3.1 6.7 P1 46.9 P2 Switchpoint adjustment Hysteresis adjustment 1.6 18.0 dimensions in mm 19.8 13.5 2 x 4.8 diam. 59.7 52.3 53.3 4 x 2.54 1 2 3 4 5 12.7 39.3 LED 30.0 44.0 mass: 18 g LED BSW...H-PCB 6.3 6.7 19.8 7.8 P2 39.3 2 x 3.5 diam. 46.9 P1 59.7 52.3 53.3 4 x 2.54 Switching adjustment Hysteresis adjustment 1 2 3 4 5 12.7 LED 30.0 1.6 33.5 mass: 21 g dimensions in mm Pin connection Pin 1 2 3 4 5 Connection +Vs Vout (analog) -Vs (GND) Switch 1 (out) Switch 2 (out) March 2001 / 016 22.8 3/4 www.sensortechnics.com 22.8 BSW Series Solid state pressure switch with analog output HYSTERESIS AND SWITCH POINT SETTING Function Hysteresis Switching point Change per scale unit ≈ 0.9 %FS ≈ 7.3 %FS ORDERING INFORMATION Part number Package version Pressure range Differential/Gage devices 0 - 70 mbar 0 - 350 mbar 0 - 1 bar 0 - 2 bar 0 - 5 bar 0 - 10 bar Absolute devices 0 - 1 bar 0 - 2 bar 0 - 5 bar Side facing ports BSWM070DV-PCB BSWM350DV-PCB BSW001DV-PCB BSW002DV-PCB BSW005DV-PCB BSW010DV-PCB BSW001AV-PCB BSW002AV-PCB BSW005AV-PCB Top facing ports BSWM070DH-PCB BSWM350DH-PCB BSW001DH-PCB BSW002DH-PCB BSW005DH-PCB BSW010DH-PCB BSW001AH-PCB BSW002AH-PCB BSW005AH-PCB Sensortechnics reserves the right to make changes to any products herein.
