Important notes at the end of this document.
Pressure sensors
Absolute pressure transducers
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.
Rated pressure p
Within the rated pressure range 0 up to p
Overpressure p
Pressure cycles within the pressure range 0 up to p
Supply voltage V
V
The output voltage V
DC break down voltage V
The pressure sensor withstands a high voltage between the stainless steel pressure connection and the electrical
connection V
Offset V
The offset V
Sensitivity S
Within the pressure range 0 up to p
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:
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).
(Full Scale): FS = V
Temperature coefficients of the bridge resistance
Bridge resistance at temperature T
Values are valid within the operating temperature range T
Out of the operating temperature range, the deviation may increase.
Temperature coefficients of the sensitivity
Sensitivity at temperature T
Values are valid within the operating temperature range T
Out of the operating temperature range, the deviation may increase.
Temperature coefficient of offset TCV
Offset at temperature T
Values are valid within the operating temperature range T
Out of the operating temperature range, the deviation may increase.
