The minimum supply voltage is directly proportional to the load resistance seen by the transmitter. For more details see the
load limitation diagram.
Proof pressure is the maximum pressure which may be applied without causing damage to the sensing element.
The output signal of all 141SC...-PCB devices is proportional to the vacuum applied to port B, relative to port A, e. g. the output
signal increases when pressure is applied to port A relative to port B.
The output signal of all 142SC...D-PCB and 143SC...D-PCB devices is proportional to the pressure applied to port B, relative to
port A, e.g. the output signal increases when vacuum is applied to port A relative to port B.
The output signal of all 142SC...A-PCB is proportional to the pressure applied to port A.
Full scale span is the algebraic difference between the positive full scale output and the zero pressure offset.
Non-linearity refers to the Best Straight Line fit measured for offset pressure, full scale pressure and 1/2 full scale pressure.
Thermal effects tested and guaranteed from 0 - 70°C relative to 25°C. All specifications shown are relative to 25°C.
Change in output after one year or 1 million pressure cycles.
