Characteristics
■ Operating characteristics
Positive pressure (at rated pressure 0 to 50 kPa)
Negative pressure (at rated pressure 0 to -50 kPa)
Note: 1. The above values are initial values.
Note: 2. Ambient temperature condition: 23°C without Temperature property.
Note: 3. The above values are operated at 100 µADC
Note: 4. The above values are operated at 0 to 50 kPa, and 0 to -50 kPa.
Note: 5. Offset voltage is defined as the output voltage at 0 kPa rated pressure.
Note: 6. Positive span voltage is defined as the algebraic difference between the output voltage at 50 kPa rated pressure and the output voltage at 0 kPa rated pressure.
Note: 7. Negative span voltage is defined as the algebraic difference between the output voltage at -50 kPa rated pressure and the output voltage at 0 kPa rated pres-
sure.
Note: 8. Hysteresis is defined as follows,
In case of positive pressure:
{The output voltage difference at 0 kPa before and after a pressure cycle (0 to 50 to 0 kPa)} / (span voltage) × 100 [%FS].
In case of negative pressure:
{The output voltage difference at 0 kPa before and after a pressure cycle (0 to -50 to 0 kPa)} / (span voltage) × 100 [%FS].
Note: 9. Temperature influence of span voltage is defined as follows,
{Span voltage at 0°C. - span voltage at 25°C. } / span voltage at 25°C. × 100 [%FS]
{Span voltage at 50°C. - span voltage at 25°C. } / span voltage at 25°C. × 100 [%FS]
{Span voltage at 85°C. - span voltage at 25°C. } / span voltage at 25°C. × 100 [%FS]
Note: 10.Temperature influence of offset voltage is defined as follows,
{Offset voltage at 0°C. - offset voltage at 25°C. } / span voltage at 25°C. × 100 [%FS]
{Offset voltage at 50°C. - offset voltage at 25°C. } / span voltage at 25°C. × 100 [%FS]
{Offset voltage at 85°C. - offset voltage at 25°C. } / span voltage at 25°C. × 100 [%FS]
