Combined offset and span
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:
Hysteresis setting has a direct influence on the switching points
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
