Important notes at the end of this document.
Pressure sensors
Barometric pressure transmitters for SMT (voltage output)
Storage temperature range T
A storage of the pressure sensor within the temperature range T
and without applied pressure and supply voltage will not affect the performance of the pressure sensor.
Operating temperature range T
An operation of the pressure sensor within the temperature range T
will not affect the performance of the pressure sensor.
Compensated temperature range T
While operating the pressure sensor within the temperature range T
the deviation of the output signal from the values at 25 ° C will not exceed the temperature coefficients.
Out of the compensated temperature range, the deviations may increase.
Rated pressure p
Within the rated pressure range p
Overpressure p
Pressure cycles within the pressure range 0 up to p

I
Exceeding (e.g. short circuit) may cause irreparable damages.
Start up time t
Time between the start up of the normal operation after power on and the first valid output signal.
Offset V
The offset V
Signal span (Full Scale)
V
Nonlinearity L (including pressure hysteresis)
The nonlinearity is the deviation of the real sensor characteristic V
It can be approximated by a polynomial of second order, with the maximum at p
The equation to calculate the nonlinearity is:
Response time t
Delay between a pressure change (10 ... 90% p
Resolution r
The resolution of the output DAC (digital/analog converter). For ratiometric output only 80% of DAC range is used.
Temperature hysteresis
The temperature hysteresis is the change of offset, starting from the value at 25 ° C after a temperature change
and return to 25 ° C. Determined during temperature cycles in operating temperature range (cycles with 1 K/min).
Temperature coefficient of offset TCV
Offset at temperature T
Values are valid within the compensated temperature range T
Out of the compensated temperature range, the deviation may increase.
Temperature coefficient of span TCV
Span at temperature T
Values are valid within the compensated temperature range T
Out of the compensated temperature range, the deviation may increase.
