proportional to the differential pressure applied. side relative to the pressure side. Table 1. Maximum Ratings
- Exposure beyond the specified limits may caus e permanent damage or degradation to the device.
Table 2. Operating Characteristics (VS = 10 Vdc, TA = 25°C.)
- 1.0 kPa (kiloPascal) equals 0.145 psi.
- Device is ratiometric within this sp ecified excitation range. Operating the device above the specified excitation range may induce additional
error due to device self-heating.
- Full Scale Span (V FSS) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the
- Offset (V off) is defined as the output voltage at the minimum rated pressure.
- Accuracy (error budget) consists of the following:
and from the minimum or maximum operating temperature points, with zero differential pressure applied. minimum or maximum rated pressure, at 25°C. TcSpan: Output deviation at full rated pressure over the temperature range of 0 to 85 °C, relative to 25°C.
- Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to
a specified step change in pressure.
- Offset stability is the product's output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test.
