Symbols and terms

1)

and without applied pressure and supply voltage will not affect the performance of the pressure sensor.

2)

will not affect the performance of the pressure sensor.

3)

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.

4)

to this specification.

8)

The pressure sensor withstands a high voltage between the stainless steel casing and the electrical connection

I+ and I– (short circuited) without damage.

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).

CC0

Out of the compensated temperature range, the deviation may increase.

FS

Out of the compensated temperature range, the deviation may increase.
