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.
Compensated temperature range T c
While operating the pressure sensor within the temperature range T c,min up to T c,max ,
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 r
Within the rated pressure range 0 up to p r (symmetrical output: –p r 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 CC
V CC,max is the maximum permissible supply voltage, which can be applied without damages.
V CC,min is the minimum required supply voltage, which has to be applied for normal operation.
Signal output current I A
I A.max is the maximum permissible sink current of the signal output.
Exceeding (e.g. short circuit) may cause irreparable damages.
DC break down voltage V is
The pressure sensor withstands a high voltage between the stainless steel casing and the electrical connection
V CC , V A and GND (all short circuited) without damage.
Offset V A0
The offset V A0 is the signal output V A (p = 0) at zero pressure.
Signal span (Full Scale)
Simple output:
V FS = FS = V A (p r ) – V A0
Symmetrical output: V FS = FS = V A (+p r ) – V A (–p r )
11)
Nonlinearity L (including pressure hysteresis)
The nonlinearity is the deviation of the real sensor characteristic V A = 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:

Supply voltage rejection SVR
While varying the supply voltage within the range V CC,min up to V CC,max at constant pressure and temperature,
the signal output change will not exceed SVR max .
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 A0
Offset at temperature T x : V A0 (T x ) = V A0 (25 °C) + V FS (25 °C) · (T x – 25 °C) · TCV A0
Values are valid within the compensated temperature range T c,min up to T c,max
Out of the compensated temperature range, the deviation may increase.
Temperature coefficient of span TCV FS
Span at temperature T x : V FS (T x ) = V FS (25 °C) · [ 1 + (T x – 25 °C) · TCV FS ]
Values are valid within the compensated temperature range T c,min up to T c,max
Out of the compensated temperature range, the deviation may increase.
