Storage temperature range T st
A storage of the pressure sensor within the temperature range T st,min up to T st,max
and without applied pressure and supply voltage will not affect the performance of the pressure sensor.
Operating temperature range T a
An operation of the pressure sensor within the temperature range T a,min up to T a,max
will not affect the performance of the pressure sensor.
Rated pressure p r
Within the rated pressure range 0 up to p r the signal output characteristic corresponds to this specification.
Overpressure p OV
Pressure cycles within the pressure range 0 up to p ov will not affect the performance of the pressure sensor.
Supply voltage V DD
V DD,max is the maximum permissible supply voltage, which can be applied without damages.
The output voltage V out is ratiometric (V out ~ V DD ).
Offset V 0
The offset V 0 is the signal output V out (p = 0) at zero pressure.
Sensitivity S
Within the pressure range 0 up to p r the output voltage is V out (p x ) = V 0 + S · p x
Nonlinearity L (including pressure hysteresis)
The nonlinearity is the deviation of the real sensor characteristic V out = f(p) from the ideal straight line.
It can be approximated by a polynomial of second order, with the maximum at p x = p r / 2 .
The equation to calculate the nonlinearity is:
? x

Temperature hysteresis
L =
V out (p x ) ? V 0
V out ( p r ) ? V 0
p
p r
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).
(Full Scale): FS = V FS = S · p r
Bridge resistance at temperature T x : R S (T x ) = R S (25 °C) · [ 1 + α RS · (T x – 25 °C) + β RS · (T x – 25 °C) ]
Sensitivity at temperature T x : S(T x ) = S(25 °C) · [ 1 + α S · (T x – 25 °C) + β S · (T x – 25 °C) ]

Temperature coefficients of the bridge resistance α RS , β RS
Values are valid within the operating temperature range T a,min up to T a,max
Out of the operating temperature range, the deviation may increase.
Temperature coefficients of the sensitivity α S , β S
Values are valid within the operating temperature range T a,min up to T a,max
Out of the operating temperature range, the deviation may increase.
Temperature coefficient of offset TCV 0
Offset at temperature T x : V 0 (T x ) = V 0 (25 °C) + TCV 0 · (T x – 25 °C) · V DD
Values are valid within the operating temperature range T a,min up to T a,max
Out of the operating temperature range, the deviation may increase.
