configurations
APPLICATIONS
• Medical equipment
• Respiration
• HVAC
• Level detection
• Flow measurement
• Industrial control

Notes:
1. Positive Pressure is defined as entry on the bottom side of the die; gain, during factory calibration, is set using negative pressure
2. For the SM5652, 0.15 PSI range, span is 23.75 (min) to 26.25 (max).
3. Measured over a temperature range of 0 to 60 oC.
For 0.15 PSI, TC Span=±2.0%FS; TC Offset=±2.0%FS; For 0.3 PSI, TC Span==±0.75%FS
4. For 0.30 PSI, Hysteresis=±0.45%FS;
For 0.15 PSI, Hysteresis=±0.65%FS
5. Best fit straight line; measured from top-side of die
For 0.30 PSI, Linearity=±0.5%FS;
For 0.15 PSI, Linearity=±2.5%FS
6. Sensitivity matching relates to part-to-part matching
For 0.15 PSI, Sensitivity Matching=5.0%FS
