Proof pressure is the maximum pressure which may be applied without causing damage to the sensing element.
The output signal of all 144S...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 144S...A-PCB and 144SC...BARO devices 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 to 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.
These devices are factory calibrated at sea level. When used at other altitudes the output signal differs from the reading
expected when comparing to the pressure given from your local weather station. The weather station always reports the pressure
compared to sea level. On that the output signal of the transducer will change 65mV/0.052 psi per 100 feet e.g. 19.7mV/1.18
mbar per 10 m change in altitude. The output signal can be adjusted to sea level reading by turning the offset trimmer.
Thermal effects refer to the combined effects of offset and sensitivity shifts, this is true from -10 to 60°C relative to 25°C.
