19 mm Series Notes: 1. Reference conditions (unless otherwise noted): TA = 25 °C [77 °F]; 19C Supply VS = 10 Vdc ±0.01 Vdc or IS = 1.5 mA ±0.0015 mA; 19U Supply VS = 5 Vdc ±0.01 Vdc or I = 1.0 mA ±0.0015 mA. 2. Full-scale span (FSS) is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure. FSS is ratiometric to supply voltage. 3. Pressure non-linearity is based on best-fit straight line from zero to the full-scale pressure. Pressure hysteresis is the maximum output difference at any point within the operation pressure range for increasing and decreasing pressure. 4. Maximum error band of the offset voltage or span over the compensated temperature range, relative to the 25 °C [77 °F] reading. 5. Long-term stability over a six-month period. 6. Response time for a 0 psi to FSS pressure step change, 10% to 90% rise time. 7. The maximum pressure that can be applied without changing the transducer’s performance or accuracy. 8. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer 9. Common mode voltage as measured from output to ground. For higher levels of common mode voltage, contact factory. 10. The error band resulting from a maximum deviation of a transducer’s output parameter (offset, span, or resistance) as temperature is varied 25 °C [77 °F] to any other temperature within the specified range (0 °C to 82 °C [32 °F to 180 °F]). This parameter is not 100% tested and is guaranteed by process design and tested on a sample basis only. Temperature coefficient of span is evaluated using a 1 mA constant current excitation source. 11. Vacuum gage products may be affected by changes in environmental humidity levels. The specifications shown exclude these effects. PHYSICAL DIMENSIONS (For reference only: mm [in].)
